Re: More proof of evolution
Thanks for the heads up Bob. Bet you that mimivirus gets a fair few mentions next time we're debating abiogenesis :)

Re: More proof of evolution
I was not able to check and keep up on the topic, from after i posted my report, to  page 12. 6 pages of hellish-longly pages like this one. Add on another 3-4 from last night till tonight. I have alot to read and you all dont realize how much time i have spent trying to keep up reading from page 6-  here. Be more conciterite. And FFS stop pressing me. Give me time to keep up before you demand quick answers now to your recent questions. I am trying my best. I dont have infinite time. I have to work soon and im still reading this ****. Give me some credit.
I guess I will make just a few responses, just to get into the discussion a little.  My replies are given in blue.


Man was made by God to live forever and never die. But sin came and our lifes keep getting shorter. Sin affects our gentics over the generations and causes us to live less. It has greater and greater toll on our lifes.  --> So why have life spans been growing longer for the past several thousand years, and explosively so during the past few hundred?  Less sin?:rolleyes:
Also, do you have any _empirical_ evidence to support this theory?  Have sinners been found to get more genetic mutations?

I think the last limit God set for man was ~ 120 years. We are just getting better health conditions and pills and **** to live around 100. Before we didnt have those and only lived to 55-60.

Please explain the correct meaning of ‘Natural Selection’, then.  -->  "Natural Selection" is where a species undergoes changes due to random mutations causing certain members of a population to have increased odds of surviving certain environmental pressures.  The individuals that do not get these mutations are less likely to survive, so over time, the "beneficial" mutation will become more common, and thus the species changes.  Hence the name "natural selection", meaning that "natural" environmental pressures "select" the individuals of a population that are most capable of surviving and reproducing. (This is a very simple and watered-down explanation, but I'm sure someone else can describe it in more detail.)
Thanks for explaining.

Wasent Radiocarbon dateing said to have been a flawd way of dateing things?  --> Read what was posted on the previous page about carbon dating.

Shade: God created the universe basicaly how it is. He created earth in its middle stages already. He made it as if it was there for that long- made the light already be reaching earth. This is a belief based on reasoning, not exactly facts.
How do Evolutionitsts believe the universe began?  --> Evolution doesn't discuss how the universe came to be, or has come to be the way it is now.  That discussion lies in astrophysics.  Therefore your question is (and I'm sorry for saying this), meaningless.  Some evolutionists beleive that God created the universe.  Others (like myself) go by the Big Bang Theory (though that theory can't explain what happened before the Big Bang).  But heck, a few even go by the Flying Spaghetti Monster Theory.:p
Evolutionists beleive (some do) that God created the universe? That seems like irony right there.

There were animals that died before the flood. Mostlikely a good deal of time before the flood. That explains why their older.  --> So why are there fossils dated back to before you believe the Earth was created?  If you are going to respond to this by saying that there is a flaw in the dating techniques, then you must say what that flaw is, and the evidence to support it.  Otherwise, you're statement is not a valid arguement, and instead only conjecture.
As i said, il look it up when i have the chance. Sorry but i do not have time to check in the wiki yet.

Their skincolor is unknown and extremely irrevelant. When they had enough decendents, they split up (After the tower of babel, and the newly developed different languages) and went different ways. They form then, in their respective area, over the thousands of years, their physical appearance changed to the respects of their surrondings ect. Skin color, and probably bone structures changed alittle, as iv stated before. -->  Ahem.  THAT... IS... EVOLUTION.
And here's why:  You're saying that their physical appearance changed due to the enviroment.  For example, the population that recieves greater exposure to sunlight gets darker skin over time.  This would be due to individuals in the population who have more skin pigment to have higher survival rates in those climates.  This is precisely what evolution is, so, if I understand your above statment correctly, you have just admitted that evolution is plausible, which is in direct contradiction to your entire arguement.  If I have made a misunderstanding about what you meant there, then by all means tell us how what you stated is different from evolution.
 
Well, you missed what i said, apparently. I said on a smaller scale. Its 'changing' not really 'evolving\evolution'.

Ok, that's all.  It's 3:00 AM here and I reeeaaally require sleep.

ugh, so much...
one thing that's irking me a bit, intelegent design, it is on your side. it says an intelegent designer made the universe, it doesn't come out and say it is God but it's implied, you need to understand ID is creationists trying to use what they see as a loophole in the law to get as much creationism into schools as posable, ID does not contradict creationism, it is simply a simplified version of it, crafted to get around laws saying to can't teach religion as science.
Well i gues your right. Never really saw it taht way before.

also you say that ages of people are getting shorter and shorter, but humans can live to be 100 years easaly today, 100 years ago you were consitered lucky to reach 60, is the world of today a less sinful place? or is that a bunch of BS that someone told you and you never bothered to look up?
See my reply to the blue.

if fossilisation only took a few thousand years, and there have been humans alive all that time then why are all the remains we have found not fossilised? why can we dig up bones from graves in cities mentioned early in the bible (so we know these bodies have been in the ground for the better part of the creationist view of the age of th earth) and they don't show the slightest hint of fossilisation, nor do any animals found in these places? if it didn't take millions of years then logicaly we should be able to dig up an egyptian grave and find fossilised bone, why don't we?
I have no reply other then: As you said youself, you need certian conditions to be perfect before thigns can fossilize. Peoples bones in graves is not the correct condition.

and it sounds like your starting to move to the "God made the earth with all sorts of fake evedence built into it" (like light from distant stars and isotope ratios) idea, if your going to go down such an intelectualy dishonest rout your beleifes must truely have no foundation in reality and you know it. it's like saying God framed us. realy, this is some hard number math stuff here, you must be willing to consiter the posability that the Bible is not a totaly relyable directory of physical knowlage, it says PI=3 (1 kings, chaper 7, vs 23, it says a circular shape that is 10 cubits wide had a circomference of 30), it IS wrong about certan facts, so you can't just blindly accept what it says, and you certanly can't go down the road of 'God made the fossils... to trik you or something'.
Im not saying that.
The exact measurements of the Arc may be not completely correct due to imperfect transilation of measurements.

Where exactly in the bible does it say that?
I said its based on reasoning, not from a direct quote in the bible.
EDIT: Also, please have some basic courtsey and quote your quotes or at least color your responses differently from the quotations.
Sorry.
Kindly quote what you are responding to next time. I've done you the service of doing this, even going so far as to make sure that every time I've quoted you I've kept your colour.

He took every species that was avalible that day and age. Maby not stuff like plankton or fish tho. The simpler versions. Like before dogs interbreeded to make the vast majority of types of dogs there are today.

So you admit that selected breeding can result in the accumulation of large changes then? You admit that in the 4000 years since your supposed flood humans have been able to breed everything from the great dane to the chihuahua? Well at least that's an improvement on the last person I argued with who claimed that chihuahuas weren't selectively bred and had been around since biblical times :rolleyes:
Thanks for the compliment.

The ‘clean’ animals were taken 7 male and 7 female of each species. The ‘unclean’ were by 3’s. IIRC. Someone mentioned that the bible contradicted itself there. I don’t know what they are talking about, as it is clear of the numbers of each.

Oh for ****'s sake do I now have to correct you about your own religion too? :lol:
Did i not say i didnt have my bible around to be correct on quote scripture?
Quote
6:18 But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee.
6:19 And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.
6:20 Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive.

which is somewhat contradicted by

Quote
7:1 And the LORD said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.
7:2 Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.
7:3 Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.
7:4 For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth.


Now I'm sure that there is some stock christian argument to explain that discrepancy, spare me it. I don't particularly care. I mearly quoted it seeing as how you were wondering what the contradiction was. What's important is the the belief that the animals went onto the ark two by two is such a well known part of the whole Noah myth that I'm forced to conclude that you can't know much about the bible either.
Well thi sis interesting. Il find out about it and get back to you.
Quote
As for finding every species; he had plenty of time, and its very likely God caused the animals to come to him, or the like, so he could complete his task of captureing every species.

I think you miss the point. You simply could not fit two every single creature onto the Ark. Remember that we know exactly how big the Ark is. It's 450 feet long. You're expecting this to carry not only all the animals but also food to feed them for at least 7 months! It simply wouldn't all fit.
See above (one of the last replys of mine before your reply)

The Canopy theory explains this. The canopy served as a shiled, and let only a few of the UV and Gamma rays of the sun, to hit the earth. Light was able to come to the earth, but the bad rays were stopped. This caused people to live near 1000 years. Plants were hudge. Trees were giant also.

So if we were to move into lead lined bunkers underground we'd live for 1,000 years then? :lol: Sorry but that is ludicrous
There is more that goes into it then simply less radiation. There is a way less amount of nutrients in plants and the soil (the earth basicaly) nowadays, then there was back then. The canopy caused the rapid and large growth of animals humans and plants. The great amounts of nutrients is the factor that helped with prolonging life and maintianing ones body. Took longer to break the body down (age) ect.

Kara: I must prove a designer is needed before I can claim that? What? Must the pot prove it needs a clay(pot)maker before it can say it was made\designed? Your argument is fallacious.

No it isn't. I pointed to a snowflake as an example of a complex design that occurs due to natural processes and you completely ignored me and simply restated your original answer with barely any changes. If you look at a snowflake under a microscope it looks like it was designed as it has a beautiful pattern to it. Now someone without knowledge of how a crystal forms would look at that snowflake and say "That must have been designed. There is no way something that complex could have happened on its own."
 Anyone who said that would be wrong. We understand how and why ice crystals form in patterns like that due to the interactions between the water molecules that make it up.
 It is the same with other forms of complexity. You cannot simply state "There must be a designer" while there is an alternative scientific theory that explains the same facts without using one. You may not believe that complexity like this could exist without a designer but that doesn't make you right. I already explained elsewhere using the example of how the world being round that just because something seems unbelieveable doesn't mean it is impossible.
 Before you can say that there must be a designer you need to prove it.
I have no responce to this. (About the snowflake thing.)

How does a simple cell one day decide, ‘im going to get more complex’? Take this for example. The beginning cells, when a baby is created, have all the info for ‘what every other cell I make will do’. Each cell has its own job, function, wether to make an ear or eye etc. They do what their programmed to do. The origional cell(s) have all the ‘blueprints’, and it does not simply change them.

There's an attempt at a question here which I am not grasping. Are you asking why single celled organisms evolved into multi-cellular ones or asking some kind of question about development or something else? If you're going to ask me a question you need to state it more clearly. You ramble on about inconsequencial matters so much that it's hard to pick the signal out from the noise.
Did you get what i said about the few beginning cells, when creating a baby? They have the 'blueprints' of what each cell they duplicate from that point- what they will do. They all have functions. Cant change them. So, how can they decide to become more complex or change from their planned purpose?
Quote
Please explain the correct meaning of ‘Natural Selection’, then.

Natural Selection means that animals whose genes express benificial adaptations will tend to have more offspring who will also possess those genes. As a result those genes will become more widespread within the population.
Natural Selection does not require catastrophies to work as you claimed.

Radiocarbon dating is not flawed. Its accuracy is limited to around 50,000 years or so but that is not a flaw any more than the fact a car can't fly is a flaw. When used for the task it is good for radiocarbon dating is pretty accurate.

FFS. What I said about ID was not wrong. Prove your soruces. Mine said, well, what I said. There is an intellegent force, not god. They fight christianity and evolution at the same time. Some may be ‘predominately’ christian, but they sure as heck don’t claim they are. They say some being is doing it. Not god. They mean god but they don’t say its ‘god’.

You have fundementally misunderstood what ID is and have simply assumed that it is a belief that disagrees with evolution and creationism. This is wrong.

The Supreme Court of America has ruled that the teaching of creationism in schools contravenes the constitution. Namely the seperation of church and state (I'm not getting into an argument as to whether this is fair. I'm simply stating it as a fact so save your breath). Some people (mainly christians) disliked this. They wanted to be able to teach creationism in schools but now they couldn't do so. Instead they took several of the arrguments you've tried to use, scribbled out the word God in them and presented them again calling it Intelligent Design and then petitioned to get this taught in schools.
ID is basically creationism like yours but with no mention of God. God is not mentioned not because they don't believe in him but because the second they actually mention God the supreme court will come down on them like a ton of bricks.
 So your claim that IDers denounce christianity is completely incorrect. IDers are very strongly christian. They simply don't talk about God when arguing about ID because they know it would instantly torpedo their entire argument.

How do Evolutionitsts believe the universe began?

In a variety of ways. Roman Catholics believe that God created it. As do many Christians who agree with it. Other people think that the Big Bang was the start. Others favoured other theories or beliefs. You are still failing to see that how the universe started is completely irrelevant to this thread.
Just trying to understnad the different aspects of Evolution etc, as you repeditely claim i misunderstand.

Re: More proof of evolution
[q]I think the last limit God set for man was ~ 120 years. We are just getting better health conditions and pills and **** to live around 100. Before we didnt have those and only lived to 55-60.[/q]

The worlds oldest (verified) person was 122 years old; Jeanne Calmert who died in 1997.  There have of course been claims of older people (such as 128 in the Phillipines), but the lack of documentation makes it harder to verify.

[q]
Evolutionists beleive (some do) that God created the universe? That seems like irony right there.[/q]

Um, no, not irony.  Irony would imply 'a contrast or an incongruity between what is stated and what is really meant', and evolution doesn't state anything about the creation of the universe (or creation of life for that matter).

There is no connection between how the universe was created and the theory of evolution.  Both are disparate theories and actually in different fields; evolution is biology and (for example the big bang theory) the creation of the universe is more related to physics.   i.e. evolution has nothing to do with the creation of the universe.

It's worth noting.  Evolution doesn't deny or even address the existence of (a) God; it just gives the best explanation fitting the observable world and evidence.

[q]Well, you missed what i said, apparently. I said on a smaller scale. Its 'changing' not really 'evolving\evolution'.[/q]

Evolution is change.  you've made the mistake of confusing the cumulative action of evolution to being evolution itself; evolution is a process of gradual, selected very small steps that build up into larger morphological-type changes, speciation, etc.  This is one of the reasons transitional evidence is so important.

EDIT; to be precise, evolution involves a process of continuous incremental changes.  Selected by sexual or fitness advantage, etc.

[q]I have no reply other then: As you said youself, you need certian conditions to be perfect before thigns can fossilize. Peoples bones in graves is not the correct condition.[/q]

What makes you think the conditions for fossilization are not present?  We have egyptian commoners from the time of Moses who were found in the correct conditions; we can measure the known date of their burial (approx date), correlate it with carbon dating (it's within the realms of that method to do so) and known history, and compare the progress of mineralization (remember how fossils are made?) in those remains. 

I think Bob made a slight omission or mistake in the use of fossilization, because it might not be clear here; a fossil is a bone/hard tissue (or sometimes soft tissue - rapid burial is required for these) that has had its molecules completely replaced by minerals and thus become stone.  This is by no means an instantaneous process, and as said above we can check the rate of progress in relatively 'modern' remains (modern in geological terms).

[q]Im not saying that.
The exact measurements of the Arc may be not completely correct due to imperfect transilation of measurements.[/q]

Um, even to have the minimal size of ark for the lowest possible estimate of animals, bearing in mind you'd need a survivable number of animals (which would contradict both by pairs or even in 7s, because you need about 20+ for any hope of survival of a species and predators need a high prey ratio for both to survive), you'd still be looking at a truly vast ship, probably larger than anything we can build today.  You'd also need for even the specified size to have different building methods from that described in the bible (namely steel/iron reinforcements).  But I think I've covered this anyways in the earlier pages.

[q]

The canopy caused the rapid and large growth of animals humans and plants. The great amounts of nutrients is the factor that helped with prolonging life and maintianing ones body. Took longer to break the body down (age) ect.[/q]

Do you have any supporting evidence or a source for that?  I've never heard anything like that suggested anywhere.

[q]Did you get what i said about the few beginning cells, when creating a baby? They have the 'blueprints' of what each cell they duplicate from that point- what they will do. They all have functions. Cant change them. So, how can they decide to become more complex or change from their planned purpose?[/q]

They don't 'decide'. They mutate.  You'll have, on average, about 7 mutations within your genetic code.  Most will be neutral, so they don't have any observable effect and don't propagate across the species.  Sometimes, you will have some mutation that makes you live longer, more sexually attractive, etc.  (this is more applicable to animals and small populations due to the effects of human society making it both quite easy to survive and people likely to be monogamous)  You live longer or get more attractive, and thus can produce more children.  They gain your advantage through genetic inheritance of the advantageous mutation, and live longer and have more kids, and over time that mutation spreads to the majority of the species.  These mutations accumulate, until we get a new distinct species.  At no point is there a 'decision' made.

Essentially, a mutation changes that blueprint.  There is no conscious 'act' to mutate in a certain way; the mutation is chance.  The selection, of course, isn't; it's based on an environmental or reproductive advantage.  It's a bit like brainstorming ideas for a project, and reusing those that work for other projects.

EDIT; to be more specific.

Mutations generally happen as a result of copying DNA.  The general rate is 10^-10 to 10^-12 per base pair (a base pair is either a Thymine-Adenine or Guanine-Cytosine pair - the TA / GC letters you'll see in DNA samples; T only maps to A and G to C, which is why DNA can so efficiently replicate by splitting).  Mutations include insertion of base-pair strands, the changing of one of these 'letters' (i.e. T becomes A and we end up with AT instead of TA), or the deletion of strands.

These mutations can, for example, change the coding for a created protein.  This in turn has a biochemical effect upon the formation of the body, neutral (i.e. we can't detect it unless doing a genetic level examination), negative or positive.

You'll note there's no control mechanism to weed out negative but recessive mutations, such as a propensity for cancer or similar.  Essentially, a recessive mutation is one where the positive/normal characteristic is dominant over it; i.e. when you have 2 parents and one contributes the negative and the other the 'normal' chromosome, the normal will be asserted in the child.  It takes 2 recessive parental contributions to actually cause the characteristic to crop up.  This kind of emphasises that we have no control over this; it's really just down to chemistry, and we can't pick and choose what genes we get other than by excercising mate choice (which would lead us onto sexual selection and its implications on things like the peacocks tail or human mind, but that's something for later).

Also, it's worth noting that most positive mutations are generally lost due to things like dominance/recession; it's been estimated a mutation conferring a 1% increase in fitness is 2% likely to 'fix'; although recurring mutations obviously have an increased frequency.  Also, neutral mutations can 'fix' too.  What is key to remember here, is that natural selection means that organisms with a negative mutation as part of their DNA (i.e. affecting the organisms makeup) are more likely to die, and those with a positive mutation are more likely to live; so the relative constants of the chemical DNA action is mediated by the effects upon survival and that organism having the opportunity to reproduce.

(sorry, that might be a bit muddled sounding.  Basically, the chemical likelihood of any mutation being propagated is the same, but the likelihood of that organism surviving and reproducing affects a likelihood effect upon that chemical likelihood).

[q]Just trying to understnad the different aspects of Evolution etc, as you repeditely claim i misunderstand.[/q]

To re-emphasise; the creation of the universe is not an aspect of evolution.  It is an aspect of science, but not the specific biological theory of evolution.

The main reason, I think, that the creation of the universe has cropped in this thread as a topic is because it relates to the follies of reading the bible as a literal rather than allegorical or mythological history.

Well, you missed what we have been saying, apparently. That sort of 'changing' _IS_ an example of evolution. the only thing is the theory doesn't just explain that it happens, but how and why.
namely peole with darker skin in more equatorial environments will on average have more kids than fairer skined people, because darker skin is more adapted to that environment, these kids will on average have more darker skined genes than the population in general and also have the advantage there parent had, and thus have more kids themselves, eventualy the trait exsists in the entier population. this is the process of evolution in action.

Re: More proof of evolution
Thinking about it.... a skin colour and facial structure change is a pretty bloody big morphological change.

NB: Bob, one of the specific theories relating to skin colour is vitamin D absorption.  Vitamin D is toxic in large doses, but vital for the body, and darker skins are good for blocking excess vitamin D in tropical climates ala Africa, whereas lighter skins increase the rate of absorption for colder i.e. european climates.  Mentioned this earlier, but it seems to have been ingored.

As long as it means you'll stop saying that a designer MUST be present to explain complexity that's fine.

Cant change them. So, how can they decide to become more complex or change from their planned purpose?

First lets get this straight cause it's actually a pretty important distinction. DNA is not a blueprint. DNA is more like a recipe. Where as with a blue print you need to make very large changes to have a difference with a recipe you can have a huge effect with only a tiny one. If I gave you a recipe for trifle and you mistook the word jello for jelly you'd end up with something pretty different as an end product even though you've only made a 1 letter substitution.
 The effect of a mutation can be similarly far reaching (it isn't always but the point is that it has the potential to be). Let me give you an example of how a single celled organism can mutate to become a multi-celled one. This change has actually been observed under laboratory conditions mind you. (I'm simplfying the story but and example of how it actually did happen can be found here).

Suppose you take a form of single celled life form an alga. This cell reproduces by division. A second cell is formed from the first within the cell membrane and then it breaks free and wanders off on its own. Now suppose you have a small mutation that makes it so that the new cell doesn't break out of the membrane. A simple change in the phospholipid structure could do that. (note I'm not saying that is what happened. It's just an example). You'll find that after cell division you'd end up with two cells sharing the same membrane. In essence a multi-cellular life form.
 The story doesn't end there though. This mutation is rare and generally not passed on. The alga hasn't evolved yet. It's simply displayed an interesting mutation.
 You now introduce a predator to the alga. This is another single celled organism that envelops and eats algae. The predator quite happily munches its way through the population until it comes the the mutant. Then it has a problem. The mutant is too big to be enveloped. It can't eat it. So it swims off in favour of easier prey. What we now have is a selection pressure. Whereas before the mutation no longer had any particular value it's suddenly  give the alga 100% resistance to a predator that kills its non-mutated kin. It is now that we see natural selection go into action. When the mutant has offspring they too will be immune to the effect of the predator. So you have a situation where the single celled organisms are being eaten up but the dual celled ones aren't. It shouldn't be too hard to see that as the single celled become less numerous they won't be having as many descendants. The dual celled variant however will continue spitting out kids as if nothing had ever happened. Eventually all the single celled organisms will be eaten and only the multicellular version exists. And that's evolution. We've seen a single celled life form evolve into a multicellular one.

Remember this isn't just an example. This has been shown to happen under laboratory conditions!

Re: More proof of evolution
Am I the only one who has seen this thread go literally in a complete circle from about page 13-14? I mean, i've kept up with this topic - interesting reading and all - and Charis made a long list of assertions about 10 pages ago, after which Kara, Aldo & the rest of you lads responded with clear & concise explanations/corrections. And yet, around page 13-14, Charis made the exact same assertions as if he didn't even bother to read the explanations/corrections laid out so carefully for him. Forgive me if this might  be the wrong conclusion to come to, but doesn't that imply that Charis is either not reading half the responses - thereby invalidating half the entire arguement - or simply being so close-minded as to render any attempt at correction or persuasion utterly futile?

Again, forgive me for coming to such a bleak conclusion, but the past 5 pages have effectively been a complete repeat of the 5 or so before that [excluding the spam], so either we should just give up on Charis [and the ever-so-elusive ZmaN], or we should 'pause' the discussion for a few days to give the poor blighter a respite to catch up on reading the rest of the thread, thereby giving him the opertunity to compose a much more coherent arguement that doesn't repeat the same old crap again and again and again. Seriously, i'm going to start beating my head on my Computer desk if he keeps on with his misinterpretations of practically every field of evolution [& beyond], like his baffling belief that the Big Bang theory and Abiogenesis somehow enters into the general Theory of Evolution!

On another note, i'm thinking he feels as if Evolution [Charis, could you please stop referring to proponents of Evolution as 'evolutionists' as if it were some religion] is in some way an attack on his God, which would explain his fervor at defending Creationism...

Evolution is not an attack on Faith or God. It is a theory based on collected observations, and in no way invalidates or attempts to disprove the existance of a Divine Being such as your God.

I get derided as a whacko nutjob racist fascist in some places for saying such things and putting the proper name to it: eugenics.


I would like to thank certain asshats in history who have abused and misapplied that concept.

I guess that depends quite a bit whether you latch onto the older usage in Greece by the likes of Plato, or Francis Galtons more recent (1800s) adoption of the idea which suggested financial incentives for marriage between upper class families (to fair, Galton opposed the idea of state compulsion).

To be honest, though, we already practice eugenics in the sense of mate choice, so it's hard to see what the term (as it's usually applied) adds beyond the concept of some societal (re?) enforcement of class divisions.

it would be some (government) organised program to make better people.

I don't like the idea of eugenics, I prefer direct manipulation of the genome, rather than breeding programs.

It bugs me when people call DNA a blueprint because that implies a 1 to 1 mapping between sections of DNA and sections of the body. This mistake is the basis of a large amount of crappy sci-fi that assumes that if you re-write the DNA you can re-write the rest of the body.

Far better to call it a recipe and end the misconception. Especially as the term blueprint invoked the idea of an architect to create it.

You know what I see wrong about scifi like Star Trek is that they have not only have 2 different species successfully procreating, but species from 2 different planets!

Calling it a recipe does not end the misconception. The english language itself causes the misconception. IMO there is no difference between what the word recipe or blueprint means. It is only what you perceive the word as. Example. "I have a recipe for success", "I have a blueprint for success", or "I have a guide for success". All three phrases mean the exact same thing to me, but only one word has been changed in each. But lets move back to your other example and pretend every person on earth perceives the word recipe as when one small change is made it has huge impact. If someone was to say mistake meter for foot within a blueprint for something, wouldnt that also have a huge impact?

I'm not saying you are wrong in the point you were making. I am just pointing out how the english language is what will cause the misconception. :p

Ok, for one i have been keeping up as best i can (see my last reply). A gap from page 7 to, what was it, 12(?) i havent read yet. Im workin on it. The reason i have been regurgetating answers is because, its all i can do for my defence agiesnst some topic. Then everyone yells at me about it and picks it (and me) apart. Then i learn alittle more. Im getting there. You guys have actually made me think about some of these things, which i havent thought about before.
I have readed this page. I actually think i understand Mutation and Natural Selection in its generalities now, thanks to Aldo and Kara.

Im workin on reading page 7 now. I hope this thread dont spurt another 3-4 pages sence i post this. Lol. (Yet)

The reason for annoyance is because we quite often have already addressed it and, whilst i understand it's rather a large thread to pick through, it's rather frustrating to have to restate the same things several times.
