Bonobos may have entered the Stone Age. For the first time ever, scientists have seen bonobos making sophisticated use of pre-agricultural tools in a way that's similar to what archaic pre-humans once did.
It turns out that bonobos may have "speech" that similar to humans.
Chimps and bonobos are closely related, but one may be better at using tools than the other. Scientists have found that chimpanzees innately know how to use tools while bonobos don't.
Are humans the only creatures that can feel empathy? It's a question that's still under debate.
Some animals, like humans, can sense and respond to a musical beat, a finding that has implications for understanding how the skill evolved, scientists said on Saturday.
While bonobos and chimpanzees are similar at birth, they very quickly develop different behavioral patterns later in life. Now, scientists may have found out why. They've discovered that bonobos retain an elevated hormone level which changes their behavior for years to come.
