The modern house cat reached China in the 8th century. Before that, another cat — the leopard cat — hunted the rodents in ancient Chinese settlements.
An ancient, shared set of human-specific genes underwent changes in a geographically isolated population after around 300,000 years ago, scientists say.
Ancient collagen preserved in the bones of extinct Australian mammals is revealing their evolutionary relationships, leading to some surprises.
Colorful lichen living on dinosaur bones reflect infrared light that can be detected by drones, which might lead to finds in remote areas.
The grisly infrared camera footage records a never-before-seen hunting tactic. It may have implications for bat conservation.
The American Museum of Natural History’s “Impact: The End of the Age of the Dinosaurs” examines how an asteroid impact shaped life as we know it.
Simple chemistry could give the reindeer his famously bright snout. But physics would make it look different colors from the ground.
