A hairy, naked male and a hairy, naked female crouch over the body of an antelope they’ve just killed. They’re looking up with fear and fight in their faces as a huge bird of prey swoops down to try to steal their kill. A jackal lurks in the background, biding its time. It’s a frozen moment from 100,000 years ago, a flash in the life of a Neanderthal couple, reconstructed by scientists for a diorama at the Museum of Natural History.
