started by thisso the evolution game, one or more primitive animals (or plants, for simplisity when ever I say animal from now on in this post I mean organism) will be put up and from them we will _very slowly_ imagine them evolveing.
some rules:
1)with the exeption of the first one or two animals you must use an exsisting animal as the template for your animal
1a)in the first round base animals must be reasonably simplistic as to be reasonable to expect to come from a clump of single celled organisms, at a certan point base animals must be closed out because we're assumeing these things are comeing about at about the same time.
2) if you add something to an animal, you have to go into extreem detail as to how that addition came from, you can't just say "it evolved eyes" or "it evolved fingers" you have to say were these apendages came from and what sorts of mutations led to them
3)were starting off on a world populated by single celled organisms of varying biochemistry. to make things interesting there were (at least) two seperate abiogenisis events giveing rise to two diferent lines of life.
first is the Germanium line, organisims princibly made up of Germanium Selenium, and Hydrogen, also utaliseing Arsnic, Antimony, and Tellurium (as well as smaller amounts of most other elements), this line has many members who are sensitive to free Selenium and produce it as a waist product (they use sunlight to make GeSe sugar like molicules out of Germanium Diselenide similar to how plants use the energy of the sun to do the same with carbon and oxygen) while other members are able to use free Selenium as an energy source and produce Germanium Diselenide as waist.
second is the silicon line, principly made of silicon, sulfur and hydrogen, also utaliseing phospherus, arsnic, and selenium (in addition to small amounts most other ellements). like the carbon line there are some members sensitive to free sulfur produceing it as a waist product (the heat of geothermal vents to brake silicon disulfide into something similar to sugars and free sulfer wich they release as waist) and others that use free sulur as an energy source produceing silicon disulfide as waist.
these two lines do not directly compete for resounces generaly (other than space), and there biochemistry is largely incompatable so they don't tend to eat each other (at this point).
4) the planet we'er on is 1.3 times the mass of earth, it's atmosphere consists of mostly Argon with signifigant amounts of Sulfur and Selenium present. it orbits a stable binary system both stars have signifigantly buler spectrums than our sun.
so to start off the game I'm proposeing the following base animal.
comeing from baceria of the germanium line wich developed a survival stratigy of growing into clusters for defence, and later developed specalisation based on there location in the group. this organism is essentaly a giant stomoch. it has a single opening on the top of it wich opens into a large sack lined with three specalised cells. one type removes water and other relitively useless chemicals from the sac pumping it through the lineing of the sac into the main tishues of the sack wich eventualy expell them through the outer lineing. the second type are ensomites, they produce a ensyme that breakes down just about any germanium based organism that ends up in the gut they also produce a protective slime that prevents the ensyme from breakeing down the stomach wall. and the third cell absobs nutrients digested by the ensyme. the three work in a particular order, when the sack is filled the water pumpers remove as much as they can as fast as they can when there job becomes suficently dificult (they've removed most of the water) they stop working and relese a chemical trigger that alerts the ensimites to produce there slime, and then the digestive ensime, similar queues tell them when to stop and the absorbers to start, when the absorbers are done all that is left is mostly unusable/toxic wais wich is expelled when the organism inflates the sac. now the wall of the organism is mostly a specalised cell type, it has a protene structure on it's surface that causes it's membrane to be a partucular ovaliod shape but when exposed to the right chemical triggers can reverse it's shape, with many of these cells linked together it has a primitive musle cell. it has many bands of these cells linked together to form bands around it's body, when in there relaxed state they compress the stomoch cavity, when stimulated they expand the body sucking in the surounding water and the thick slime of single celled organisms and nutrients within it. in addition it has two large lobes of muscle on either side of the stomach opening (the mouth) that in there relaxed state close the mouth, but open it when stimulated.
this organism lives near the surface of the water were there is an extreem abundance of germanium based life forming a thick dark purpleish soup (the algelike organisms specalise more on the blue end of the spectrum makeing there light absorbing chemicals more reddish than the chlorophyll of plants on earth)
it reproduces via spore like buds that float away in the water.
now you only have to go into this much detail if your makeing a base organism
and a piture of the beasty, wich is why it's in the art forum.
I'll try makeing a few variants to get things moveing if no one else does
