The team, working in Gabon, say they discovered evidence deep within rocks showing environmental conditions for animal life 2.1 billion years ago.

But they say the organisms were restricted to an inland sea, did not spread globally and eventually died out.

The ideas are a big departure from conventional thinking and not all scientists agree.

Most experts believe animal life began around 635 million years ago.
