Scientists have shown that anatomically modern humans spread from Africa to Asia and Europe in several migratory movements. The first ancestors of today’s non-African peoples probably took a southern route through the Arabian Peninsula as early as 130,000 years ago, the researchers found."

A Michigan boy exploring a creek finds what looks like a really big, really old tooth
The tooth is 8 inches in length, brown, and has six peaks

Mastodons were elephant-like beasts that roamed North America 10,000 years ago
It is from Darwin that we inherit the ideas that domestication involved isolation of captive animals from wild species and total human control over breeding and animal care.
But animal management in this industrial setting has been applied too broadly in time and space, said Fiona Marshall, PhD, professor of anthropology at Washington University in St. Louis. It is not representative of the practices of the Neolithic herders who first domesticated animals nor — for that matter — of contemporary herders in nonindustrial societies.
Together with Keith Dobney, PhD, of the University of Aberdeen in Scotland; Tim Denham, PhD, of the Australian National University; and José Capriles, PhD, of the Universidad de Tarapacá in Chile, Marshall wrote a review article that summarizes recent research on the domestication of large herbivores for “The Modern View of Domestication,” a special feature of The Proceedings of the National Academy of Sciences published April 29.
Recent research on the domestication of donkeys, camelids (which includes dromedaries, Bactrian camels, llamas and alpacas) pigs, cattle, sheep and goats suggests that neither intentional breeding nor genetic isolation were as significant as traditionally thought, the scientists said.
“Our findings show little control of breeding, particularly of domestic females, and indicate long-term gene flow, or interbreeding, between managed and wild animal populations,” Marshall said.
Why is it important to get domestication right? “Our livestock is losing genetic diversity even faster than some wild animals, because of management practices like artificial insemination,” Marshall said. “We took only a bit of the diversity from the wild for domestication, and what we’re looking at now is lopping it off really fast so we’ll be left with little diversity to survive all the climate and disease issues we’re facing. It really is a crisis situation.
“If we don’t understand what it is we might be about to lose, then we don’t count the cost of loss accurately or know how to plan for the future,” she said".
