West Australian fossil find rewrites land mammal evolution

...history than previously thought," Mr Fitzgerald, a researcher in the School of Geosciences, said. "This means that humans can trace their evolutionary roots, and adaptations for life on land, further back in time, to more than 380 million years ago. "This little fossil fish, Gogonasus, is therefore the ultim...
