A new member of the human family?

Scientists say they have uncovered the remains of a new human-like species in a South African cave.

It is one of the greatest fossil discoveries of our time, a trove of bones hidden deep inside a cave, outside Johannesburg in South Africa.

The team of scientists - from the Rising Star expedition - who made the discovery say the remains are that of 'Homo Naledi'. A new species of our human ancestor.

Homo Naledi is small-brained and primitive - yet revolutionary and complex in behaviour.

Its place in time is uncertain.

It may have lived as far back as three-million-years ago ... or could have roamed the earth as recently as 100,000 years ago.

So, is human evolution more complicated than we thought?

And is this just the beginning of what could be a new era of discoveries.
