Scientists do away with Darwinian tradition

Scientists suggest a completely new way of classifying organisms that does away with conventional idea of species.

Cave paintings and bones reveal origins of European bison

Fossil DNA from bison bones reveals that the European bison was a cross between aurochs and bison. Cave painters depicted the species in detail, 15,000 years ago.

Bird study reveals a key assumption in evolution theory is false

A new study of fifty bird species from the Andes now rules out any possibility of predicting evolution on a single genetic mutation.

‘Penis worm’ is the ancestor of almost all living animals

Newly discovered fossils show that the now almost extinct ‘penis worm’ is the answer to understanding the origin of almost 90 per cent of animal life today.

Evolution in real time on Bear Island

Researchers tracked the northern-most freshwater fish over an entire year with surprising results.

Islands make large animals shrink and small animals grow

Grizzly-polar bear hybrids spotted in Canadian Arctic

Call it a 'pizzly' or a 'grolar bear', this new hybrid may be here to stay, say scientists. But is this the end to the polar bear as we know it or the start of a new bear species?

Evolution will make our wisdom teeth disappear

A simple mathematical formula explains why our teeth look the way they do and suggest that our wisdom teeth will eventually disappear.

New evidence that environmental change can outpace genetic adaptation

DNA analyses of a now extinct population of butterflies shows they could not adapt fast enough to habitat loss during the 20th century.

The return of the flatworm

Where does the acoel flatworm belong in the tree of life? Biologists have discussed this question for the last 20 years. Now Norwegian researchers believe they have found the answer.
