Research Reveals Chimpanzee’s Stone Tool Choices Mirror How Ancient Human Ancestors Used Them Researchers have noted a stark ...

A study of tool use among chimps, our closest living relatives, has cast light on the human evolutionary journey.

Researchers observed chimpanzees in the forests of Bossou, Guinea, noting that these primates use two tools to crack nuts: a ...

In their paper published in the Journal of Human Evolution, the group describes the way chimpanzees choose rocks to use as ...

But this was no mere snack break—it was a window into the evolutionary roots of tool use. Nutcracking for chimpanzees is a ...

Some chimpanzees appear to be more efficient at using tools to crack nuts than others within their groups. This efficiency could also give them an evolutionary advantage, since better nutcracking ...

The study focused on one of the most complex actions performed by primates: nut cracking using stone tools. In the forests of the village of Bossou in Guinea, chimpanzees form an isolated ...

Observations by Jane Goodall (shown) of wild chimpanzees using twigs to fish for termites and leaves to soak up water shock anthropologists who thought toolmaking was a defining trait of humans.

It was observed that younger chimpanzees often mimicked the tool selections of older individuals, suggesting that knowledge of effective stone tools may be passed down through generations. This ...

“It was really surprising to find no difference in efficiency between male and female chimps, because a female bias in tool use efficiency has been found in the past in chimpanzees and bonobos ...
