It's relatively easy to explore how the fossil evidence points to the evolution of species.

But due to fragmentary fossil evidence, the outlines of this journey are fuzzy.

The researchers were able to piece together this evolutionary puzzle by studying fossil evidence from before and after the atoll was flooded.

Tyrannosaurus rex was not only the most fearsome land predator, but the dinosaur would also have been able to pursue prey across rivers, fossil evidence suggests.

Studies of genetics and embryology had the potential to tease out secrets of evolutionary transformations that palaeontologists knew took place on the basis of fossil evidence.
