New research suggests Homo naledi's brain was one-third the size of humans but smarter.

A remarkable finding about an early hominin suggests that larger brains may not necessarily indicate greater intelligence after all.

Despite having hands and feet that resembled those of modern humans, Homo naledi, a hominin discovered.

In the Rising Star cave system in Africa's Cradle of Humankind in 2013, had a brain that.

Was only one-third the size of a modern human, a trait that researchers had previously attributed to .

A sign of the species' lower intelligence than its Homo sapien relatives.

But now that researchers have made the perilous journey into the Rising Star cave and found that the species.

Which lived between 335,000 and 236,000 years ago, buried its dead and marked the graves.

The idea that smarter species tend to have larger brains may have been disproved.
