WASHINGTON: Human hands have changed very little over the past 6 million years, says a new study, while chimps and orangutan hand structures have evolved notably.
When humans think about primate evolution, we tend to picture ourselves at the pinnacle. But could we be overplaying our hands?
New research suggests that human hands may actually be more primitive than the hands of other dexterous primates, like chimpanzees. The study was led by Sergio Almécija, a paleoanthropologist at Stony Brook University, and published Tuesday in Nature Communications.
Paleoanthropological studies tend to lean on the notion that human ancestors were originally monkey-like, slowly losing those traits through evolutionary time. But in some ways, that may not be entirely true.
