絶滅
The extinction of large animals by ancient humans triggered profound ecological changes that reshaped global history, according to a new essay series. In its final part, author Ed Stoddard explores how these 'aftershocks' led to denser forests in the Americas and Europe while burdening Africa with dangerous wildlife.

Scientists have reconstructed the genome of a woolly rhinoceros from a fragment of flesh found in the stomach of a wolf pup that died 14,400 years ago in Siberia. The analysis reveals the rhino was genetically healthy, with no signs of inbreeding, challenging theories about the causes of its extinction. This discovery provides the closest genetic insight yet into the species just before it vanished.
