About the cover
The age of Homo erectus, known familiarly as Peking Man, has been hotly debated. This week Shen et al. use a recently developed dating technique that computes deposits to be about 770,000 years old — about 300,000 years earlier than usually thought. The cover shows a replica skull reconstructed from several H. erectus fossils from Zhoukoudian. [Image: Skulls Unlimited International, Inc.]
