out of africa
gregladen | December 10, 2012Chris Stringer's new book, Lone Survivors: How We Came to Be the Only Humans on Earth, attempts to reconcile the age-old conflict between the "Multiregional" and "Out of Africa" hypotheses of Modern Human origins. Stringer has long been identified with the "Out of Africa" hypothesis, and his criticism of the Multiregional model pretty much still hold. In the Multiregional model, different groups of a human ancestor, i.e., Homo erectus (and friends) existed over a large region of the earth (Africa and Eurasia) and different populations of that ancestral populations evolved in parallel to…
razib | November 30, 2009Wet phases in the Sahara/Sahel region and human migration patterns in North Africa:
The carbon isotopic composition of individual plant leaf waxes (a proxy for C3 vs. C4 vegetation) in a marine sediment core collected from beneath the plume of Sahara-derived dust in northwest Africa reveals three periods during the past 192,000 years when the central Sahara/Sahel contained C3 plants (likely trees), indicating substantially wetter conditions than at present. Our data suggest that variability in the strength of Atlantic meridional overturning circulation (AMOC) is a main control on vegetation…

In our words... oh Jesus... this place is a disaster waiting to happen. In particular, we would like to introduce you to the comedically-dangerous "Tiger Splash Park," where you'll discover how tigers "instincts, intellect and feelings interact to form spontaneous, natural behavior." If that description isn't foreshadowing for the inevitable human mauling, I don't…
