The Chicken And Egg Problem, this problem refers to all species

Well, considering that sexual reproduction is a later adaptation, I think it would be safe to assume that "the chicken" came first.Before the egg/chicken cycle started, the ancestor of the chicken was a simple single celled organisim that likely divided like bacteria or amoeba. As evolution progressed simple multi-cellular life which reproduced asexualy evolved. As time went on it became advantageous to have a wider variety of genes in the pool and sexual reproduction began to develop, this inevitable lead to the development of genders.Eggs didn't come about till much later in the picture, but I think you can get the idea from here.

I dunno... I would speculate that the apearance of eggs was a gradual process. I would hypothesize that there were intermediate stages to the evolution of eggs.Furthermore, as the OT asks, what came first for all the species? It is pretty clear that genders, eggs, and reproduction in general, was a parallel evolutionary development. So the answer is not the same for all species.Like the evolution of the eye, nature has solved the problem in a large variety of ways for all the different species. Just think about the way crabs lay eggs and compare that to frogs, or snails.So I don't think even if there was an absolute "first", it would be the same answer for every species.This message has been edited by Yaro, 05-11-2005 10:29 AM

Huh?What does this have to do with anything?If I told you that modern wrist watches have less parts than older watches does that mean they didn't "evolve" from the older time pieces?Furthermore, what do you think a chromasom is that the amount of them has to do with evolutionary descent? I have never read anything that suggests evolution predicts chromasom count to increase as aspecies change over time.

1) What do you think a chromasome is?2) What is the importance of the amount of genes in a creature versus another?3) Why does gene quantity matter vs. Active/usefull genes?
