Mammals, including humans, stand out with their distinctively upright posture, a key trait that fueled their spectacular evolutionary success. Yet, the earliest known ancestors of modern mammals more ...

South American mammals present a fascinating case study in evolutionary biology, shaped by a dynamic interplay of palaeoenvironmental shifts, adaptive radiations and biogeographic isolation. The ...

Modern mammals are the result of millions of years of evolution. This video takes you back to their early forms, showing how different—and sometimes strange—they once were. It’s a reminder that nature ...
