Oh man. One thing in life i hate is those close minded religious types. Humans may have just appeared as humans from being created by god with the adam and eve story, or we may have have evolved from single celled organisms. One thing is certain though, evolution does exist, and does happen. It's part of life adapting and changing wherever it lives getting rid of what it doesn't need, and adding in maturing features for what it does need.
Human life on planet earth has had some obvious evolutionary changes as well. Humans on average are getting a lot taller and lankier, back in medieval times and before that humans were a lot shorter like 5ft or something, but they were also a lot more muscular all waving around heavy ass swords, and shields and stuff. Back then before bow and arrows humans could throw a spear a football stadiums length, probably more. Another thing about human evolution is that everyone these days just has wisdom teeth that don't come in correctly at all. Hell, some people don't even come with wisdoms anymore, or they just have some of them (i only had 3 wisdoms...the 4th just wasn't there). With teeth not coming in correctly you could say eating habits have changed or something.
Besides evolution about ourselves around here. Evolution has been proven on the galapogos islands. Scientists went there and noticed that the birds would have smaller beaks when the seeds they eat weren't hard to break into. And then when the next generation of birds comes along and the seeds need to be cracked open the same species of bird by then will have bigger beaks to do so, of course the smaller beaked birds pretty die out about this time because they don't have the big beak to break **** open with.
Anyway my point being, for all of those religious zealots, despite the creationism theory or the evolution from single celled organisms theory, evolution does exist and happens. Even if we humans were just plain old created like adam and eve, evolution is here yes and necessary. Even if we humans came from single celled organisms millions of years ago, well of course evolution is here especially. Doesn't matter which theory you use to try to figure out how we got here, it can't be proven by today's methods. But, we can explain why were are the way we are today, and why we were the way we were in any other point in the past as long as you're talking strictly about homo sapiens and not neanderthals.
In the meantime for us humans researching where we came from, it's cool as **** to study what species are related to us, i mean chimpanzees, orangutangs, and gorillas are the ****!
Anyway all of this is blurted out the mouth of a missionary anyway. I went to ukraine, turkey, and hungary for god (i'm not mormon or catholic..just your average christian). I like to keep an open mind because one philosopher said "the bible tells us how to get to heaven, not how the heavens work" (from the dark ages when people were arguing whether the earth orbitted the sun or the sun orbitted the earth from back in the days of early telescopes). Of course one further thing i hate is when people are too sheltered by their religion to not actually see in detail anything that's going on around them (bullheaded ****s).
In reality it doesn't matter if creation happened or if we evolved from other animals, we don't know, and it ultimately doesn't matter. So why do other religious people need to get defensive (i have no clue, people don't think sometimes)? This stuff is fascinating, and the more you look into both theories the more you learn.
In my head i haven't the slightest idea what vasudans may have evolved from. But, one thing is for certain they are not insectoid, and they don't really seem reptilian either.
