Around 1.5 million years ago, in what's now Kenya, a human-like figure walked across the savannah.  He was probably quite short by our standards, no taller than Danny DeVito.  But unlike Danny DeVito, this ancient figure was not human. He was a long-extinct relative of ours called Paranthropus boisei.  And now his fossilised hand bones are giving us never-before-seen insights into how he and his species lived.  You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).
