The New York Times reported that David L Reed of the University of Florida has been poking around with the DNA of human lice and the lice of other primates and monkeys, and has found some intriguing clues to human development. He has specialized in using the clues in the DNA of host specific parasites to mark the changes in the host behavior or development. (more…)
