Fossils of human ancestors are rare. You could pile all the ones that scientists have found in the back of a pickup truck.

But a remarkable site in Georgia, in the former Soviet Union, has produced a rich group of bones dating back almost 2 million years — and the discovery is shaking the family tree of human evolution.

The fossil hunters found the cache of bones more than a decade ago in a place called Dmanisi, but kept most of the find under wraps.

Now, they've lifted the veil, revealing the fossilized remains of five creatures who lived 1.8 million years ago.

RENEE MONTAGNE, HOST:

Wednesday is World Food Day, an occasion food activists like to use to call attention to world hunger. With 842 million chronically undernourished people on Earth, it's a problem that hasn't gone away.
