Anything can evolve into anything.

Anything can evolve into anything. The statement sounds laughable, but it's worth recognizing that in principal it is a true statement. Pick any two organisms on the evolutionary tree of life (ancestral or modern), and there were always be transitional forms leading from one to the other. Dawkins ex...

single-locus vs multi-locus models?

I am having trouble understanding the following paragraph in The Extended Phenotype. Can someone Please explain what you think Dawkins means by "single-locus models" and "multi-locus models"? My guess is that in the "single-locus model" the gene is defined as a single c...

if i'm not mistaken, a fossil is the remains or impression of an organism. the organism can cast an impression on a rock, but the bones don't turn into rock.

Re:

canalon and skeptic, I know about these general differences you've listed (except for the conjugation between different species) and that is why I said "special unique case of sexual reproduction". Anyway, it is not a argument worth prolonging since we already agree on the differences. My ...

Re: Question about Dawkins' The Selfish Gene

I think (although I have not read it) that that's the point of selfish gene, that genes are actually those, who drive evolution, isn't it? The book argues that genes are the unit of selection and that the organism is its throw-away survival machine. It seems to me that he was referring to the genes...

However, mating is not linked with reproduction, it is just one way to exchange DNA. canalon, I'm a bit confused of why you would accept that bacteria can be sexual, but not sexual reproducers. if we limit ourselves to the actual bacterial cell division , we can consider all instances as mitotic as...

Please rephrase your question, it's hard to understand. Are you asking what the common ancestor at terminal node 99 was a monocot or dicot?

A proper explanation to explain the benefit of sexual reproduction (between 2 partners) would be a gene-centered interpretation of natural selection not a group-centered one. A very simple one would be "the gene for sexual reproduction benefits its own propagation because chances increase of it...

Re: Common ancestor question

If there is a mutation in a particular organism's genome. Couldn't that in the long run lead to a new species and therefore make that single organism the common ancester for at least two species in the future? (the species that started from the mutation and the species without that mutation)? In ac...
