Brain folding

The neocortex is the part of the brain that enables us to speak, dream, or think. The underlying mechanism that led to the expansion of this brain region during evolution, however, is not yet understood. A research team headed ...

Grasses, mammals, and their co-evolution

After millions of years of amphibians, dinosaurs, and early mammals ruling the forests and swamps of the hot, humid Mesozoic and early Cenozoic, a new habitat emerged. Small patches of grasslands sprang up and spread as the ...

Early mammal varieties declined as flowering plants radiated

The dramatic explosion of flowering plant species that occurred about 100 million years ago was thought to have been good news for evolving mammals, providing them with new options for food and habitat. But research by geologists ...

Gut microbes' role in mammals' evolution starts to become clearer

An international collaboration led by Oregon State University scientists has made a key advance toward understanding which of the trillions of gut microbes may play important roles in how humans and other mammals evolve.

Mesozoic mammals—what do we know from China?

The most exciting findings covering Mesozoic mammals over the last two decades have come from the Jurassic and Cretaceous periods of China. Remarkably preserved fossils across nearly all major groups of Mesozoic mammals have ...

The co-evolution of plants and mammals examined

A report at the 2012 Annual Meeting of the Society of Vertebrate Paleontology in Raleigh, North Carolina, explores the idea that the evolution of flowering plants (angiosperms) during the Cretaceous Period had a profound ...
