Sex, sexiness, viruses, nematodes, and horses

Haploinsufficiency and the sex chromosomes from yeasts to humans
"orthologues of S. cerevisiae HI genes (those for which a reduction in copy number in a diploid from two to one results in significantly reduced fitness) are significantly under-represented on the X chromosomes of mammals... accumulation of HI genes on the sex chromosomes would compromise fitness in both sexes, given X chromosome inactivation in females"

Natural selection stops the evolution of male attractiveness
"lack of genetic variation that would allow an increase in sexual fitness while simultaneously maintaining nonsexual fitness"

A Virophage at the Origin of Large DNA Transposons

Computational and phylogenetic validation of nematode horizontal gene transfer

Dietary Change and Evolution of Horses in North America
