Recreating 130,000 years of mammal food webs with machine learning reveals the scope of the biodiversity crisis.

Scientists have viewed marsupial reproduction as more "primitive" than that of placental mammals. Fossils complicate that view.

The extinction of large mammals like wooly mammoths between 50,000 and 6,000 years ago led to more wildfires across the globe's grasslands.

An asteroid that struck Earth 66 million years ago killed nearly all dinosaurs, plants, and animals. So how did some creatures survive the mass extinction?

"We were able to show that the first tusks belonged to animals that came before modern mammals, called dicynodonts," researchers report.

Data scientists analyzed camera trap photos from 15 tropical rainforests to uncover a previously unknown relationship between the biodiversity of mammals and forests.

The earliest evidence of mammal social behavior goes back to the age of dinosaurs, fossils of a rodent-like creature indicate.

In addition to providing homes for endangered and threatened species, national parks can protect the trait diversity of mammals, new research finds.

New evidence suggests that the way brains work across the animal kingdom goes back to a common source, researchers report.

"Our study shows that mammal biodiversity in the tropics and subtropics today is still being shaped by ancient human events and climate changes."
