WOW David Attenborough lied to me about all those animals that evolve exagerated traits because they prefer certain traits in mates.

Weirdly it is still listed in wikipedia

http://en.wikipedia.org/wiki/Mate_choice

Quote:

Mate choice, or intersexual selection, is an evolutionary process in which selection of a mate depends on attractiveness of its traits.


Sorry I must have missed the memo when it was overturned by science. I know Darwin included this selection process under natural selection but it generally got shifted out because the evolution it creates is not neccessarily the fitess of survival driven.

WOW again can you cite evidence for those statements.

See again here is wikipedia

Inherited epigenetic effects on phenotypes have been documented in bacteria, protists, fungi, plants, and animals.

You view Biased gene conversion as a form of gene mutation???????

For me mutation is generally defined as a failure to store genetic information faithfully while genetic recombination is exactly that.

I certainly don't equate those two things but I guess it is not my area so it must be me.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
