Scientists say they've discovered a new species of human relative in the Rising Star cave in the Cradle of Humankind world heritage site outside Johannesburg

A composite skeleton of Homo naledi is surrounded by some of the hundreds of other fossil elements recovered from the Dinaledi Chamber of the cave.

"Overall, Homo naledi looks like one of the most primitive members of our genus, but it also has some surprisingly human-like features, enough to warrant placing it in the genus Homo," said John Hawks of the University of Wisconsin-Madison.

Homo naledi's feet are almost identical to ours -- indicating that it was well-suited to long distance walking.

Homo naledi's hands suggest tool-making and climbing capabilities.

The braincase of a composite male skull of Homo naledi measures just 560 cubic centimeters in volume — less than half that of the modern human skull pictured behind it.

Homo naledi's skull protected a brain about the size of an average orange, researchers say.

Homo naledi's teeth are similar to those of the earliest-known members of our genus, scientists say.

The full findings of the expedition will be unveiled in the October issue of National Geographic magazine.

"Underground astronauts" Marina Elliott and Becca Peixotto work inside the cave where fossils of Homo naledi were discovered.

The six women were able to fit through a 7-inch opening in the cave to reach the chamber where the bones were found.

"We have just encountered another species that perhaps thought about its own mortality, and went to great risk and effort to dispose of its dead in a deep, remote, chamber right behind us," Professor Lee Berger, the director of the project, told CNN.
