Monkey Business: What Howler Monkeys Can Tell us about the Role of Interbreeding in Human Evolution

ANN ARBOR — Did different species of early humans interbreed and produce offspring of mixed ancestry?

Recent genetic studies suggest that Neanderthals may have bred with anatomically modern humans tens of thousands of years ago in the Middle East, contributing to the modern human gene pool. But the findings are not universally accepted, and the fossil record has not helped to clarify the role of interbreeding, which is also known as hybridization. (more…)

Nearly One-Tenth of Hemisphere’s Mammals Unlikely to Outrun Climate Change

A safe haven could be out of reach for 9 percent of the Western Hemisphere’s mammals, and as much as 40 percent in certain regions, because the animals just won’t move swiftly enough to outpace climate change.

For the past decade scientists have outlined new areas suitable for mammals likely to be displaced as climate change first makes their current habitat inhospitable, then unlivable. For the first time a new study considers whether mammals will actually be able to move to those new areas before they are overrun by climate change. Carrie Schloss, University of Washington research analyst in environmental and forest sciences, is lead author of the paper out online the week of May 14 in the Proceedings of the National Academy of Sciences.
