over at Foreign Dispatches. An important point that I make there concerns the often misunderstood meaning of sexual selection, which is not choosing (selection) individuals to have sex with, but the selection of alleles which produce an attractive individual.
Of course, in human terms, we think of "attractive" as someone who elicits a sexual response, i.e., someone we want to have sex with. But, that is not what is important for sexual selection, i.e., for an evolutionary process. It doesn't make one iota of difference if you sleep with 100 women who have the "green hair" allele, as long as you choose to procreate with 1 woman who has the "blue hair" allele: it is the "blue hair" allele that gets selected in this case.
