yuiami 2010/11/05
Battle of the sexes - the same trait is beneficial for one sex but not the other. Believed that this is resolved only when the trait does not develop in the other trait (e.g., peacocks' tale). But this is not the case.

Phylogenetic analysis of Mexican cave scorpions suggests adaptation to caves is reversable
yuiami 2010/03/17
Phylogenetic analysis reveals that blind scorpions evolved into a cave but out of it again. They got eyes again too when they came back to the earth. This suggests that evolution could produce more general traits, pace what some say about it.

Lizard moms choose the right genes for the right gender offspring
yuiami 2010/03/06
Lizards females produce a male offspring from a larger father, and a female offspring from a smaller father. The body size affects the fitness of a male lizard, but not a female lizard.

Study reveals potential evolutionary role for same-sex attraction
Study reveals potential evolutionary role for same-sex attraction Peer-Reviewed Publication Association for Psychological Science Male homosexuality doesn't make complete sense from an evolutionary point of view. It appears that the trait is heritable, but because homosexual men are much less likely to produce offspring than heterosexual men, shouldn't the genes for this trait have been extinguish
yuiami 2010/02/19
A support for kin selection hypo on homosexuals. Homosexuals in Samor help their kins' kids more than kids in general. But one should be cautious when she applies this to the Western culture, because Samor is more closed society. The western culture evolved into a unfriendly place for gays.
