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.

Now a University of Michigan-led study of interbreeding between two species of modern-day howler monkeys in Mexico is shedding light on why it’s so difficult to confirm instances of hybridization among primates—including early humans—by relying on fossil remains. (more…)

1200 Howler Monkeys on Panama’s Barro Colorado Island

The fifth Howler Monkey census at the Smithsonian’s Barro Colorado Island research station in Panama, organized by Katie Milton, professor in the department of Environmental Science, Policy & Management at the University of California, Berkeley, revealed that monkey numbers have not changed significantly since the first census 33 years ago.
