University of Utah paleoecologist Kendra Chritz was first author of a new study debunking the idea that early human herders, moving from northern Africa to southern Africa, could not have traveled just east of Lake Victoria in Kenya some 2,000 years ago because the area was bushy, moist and filled with tsetse flies that cause deadly sleeping sickness in livestock and people. Her analysis of 86 teeth of ancient wildlife and livestock show the animals were eating a largely grassy diet in the area.
