Greg Mayer, who blogs at Jerry Coyne’s place, Why Evolution Is True, explains that fish didn’t start sex, regardless what the headlines say (what do copy editors know, anyway?).
Bacteria started sex, Mayer says. Probably about 7th grade, but it got worse in high school.
Mayer also discusses the Neanderthal genome study.
Now we know why creationists don’t study these areas of evolution: Too much sex.
You probably should bookmark that blog. I’ve added it to the science blogroll here.
