Complex behaviour such as regional accents and cultural food preferences in whales and dolphins seems to be linked to brain size.
Animals that evolved in cold parts of the world usually have lighter skin. If a light-skinned animal has blood vessels close to the surface of their ear skin, this will make the ears look pink.
The assisted dying bill in Victoria – complex and significant – is engendering less heated debate than marriage equality although both tap into some of our most fundamental fears and motivations.
Australia was once home to giant fightless birds - much bigger than today's emus and cassawories. But where did they come from, and where did they go?
Evolutionary biologists ask very similar questions about species to those asked by linguists about languages.
Younus, age 9, wants to know how people become allergic to food.
New research shows how dinosaurs suppressed their teeth and grew beaks, and then back-shifted this process from adult to embryo stage.
Two fossils found in South Africa provide direct evidence of parental care in extinct pre-mammalian ancestors.
Rather than castigate those who deny evolution, it is more useful to consider their arguments to help science explain it better
Comparing genomes of more than 200,000 people, researchers identified genetic variants that are less common in older people, suggesting natural selection continues to weed out disadvantageous traits.
Ancient whales were neither gentle, nor giants: they were smaller than those of today and judging from their teeth, a lot meaner.
Some animals seem to have missing genes – but the reality is a lot more intriguing.
Snowshoe hares in warmer zones have thinner fur, and some are not turning white in winter. As climate change warms the Northeast, will this species adapt?
Bees and home security cameras use the same complex techniques to monitor their environments.
Australia was a different place 275 million years ago - wild storms surged through icy seas, and marine animals lived a tenuous existence. But brittle stars had a survival strategy.
Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
The closest relative of Kangaroo Island's trapdoor spider lives in South Africa - and the arachnid could have arrived in Australia by oceanic migration.
Playing to the intelligent design mob, Mike Pence is simply spinning words in his war on evolutionary biology
A group of lizards in Brazil have evolved bigger heads in just 15 years thanks to their new environment.
A new evolutionary perspective on what's been a medical paradox: Why does the body use inflammation to regulate aspects of pregnancy when inflammation is also a big threat to pregnancy?
