The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the ...

Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are ...

Insects, the most diverse group of animals on Earth, trace their origins to the late Silurian or early Devonian, around 400 million years ago. Early lineages acquired powered flight and, later, ...

The largest analysis of bat genomes and fossils suggests that the first bats emerged in Europe roughly 65 million years ago and that echolocation evolved early.
