A new study suggests the platypus and echidna — the only egg-laying mammals — had a water-dwelling ancestor. The finding ...

This helps the species to be more successful in its habitat. It’s natural selection at work. In some examples of convergent evolution, species evolve the same solution to a problem but take a ...

While the concept of evolving evolution is still contentious, there are some new examples arising from studies in bacteria.

Yet, there are many examples of macroevolutionary phenomena found in the order Primates, including stasis, adaptive radiations, extinctions of entire lineages, co-evolution, and convergent evolution.

This is evidence that quite separate, independent episodes of molecular evolution occurred, with the same functional results. This is a dramatic example of convergent evolution, when organisms ...

For example, giraffes developed their elongated ... Unlike Darwin, Lamarck held that evolution was a constant process of striving toward greater complexity and perfection. Even though this belief ...

The study found that bird species who nest in tree cavities have independently evolved heightened aggression across lineages, particularly in females.

Two fossils named Ardi and Lucy provide evidence for human evolution. Both were found in Africa. Ardi is a female human-like fossilised skeleton that dates from 4.4 million years ago. Ardi's bones ...
