Two-Million-Year-Old Skull of Human ‘Cousin’ Unearthed

Australian researchers say the discovery of a two-million-year-old skull in South Africa throws more light on human evolution.

The skull was a male Paranthropus robustus, a “cousin species” to Homo erectus—a species thought to be direct ancestors of modern humans.

The two species lived around the same time, but Paranthropus robustus died out earlier.
