Bees' Evolution from Ancient Supercontinent Quicker Than Thought

Washington State University

PULLMAN, Wash. -The first bees evolved on an ancient supercontinent more than 120 million years ago, diversifying faster and spreading wider than previously suspected, a new study shows.

Led by Washington State University researchers, the study provides a new best estimate for when and where bees first evolved. Newly published in the journal Current Biology, the project reconstructed the evolutionary history of bees, estimated their antiquity, and identified their likely geographical expansion around the world.

The results indicate their point of origin was in western Gondwana, an ancient supercontinent that at that time included today's continents of Africa and South America.
