Two years ago, a team of researchers excavated the earliest and best-preserved specimen of Paranthropus robustus—our ancient cousins with jutting cheekbones, large teeth and small brains that lived from 1.2 to 2 million years ago—on an archaeological dig in South Africa’s Cradle of Humankind. With it, the team also unearthed the most compelling evidence that species in the human family tree were able to evolve in response to quick changes in the climate, reports Nicholas St. Fleur for the New York Times.
