Of lice and men (and chimps): Study tracks pace of molecular evolution

A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice. The researchers wanted to know whether evolution marches on at a steady pace in all creatures or if subtle changes in genes – substitutions of individual letters of the genetic code – occur more rapidly in some groups than in others.
