The very existence of kindness and altruism seems to contradict Darwin’s theory of evolution. So how could kind behaviour have evolved?
A group of fewer than 800 orangutans in northern Sumatra has been recognised as a new species - and they are already under threat from deforestation.
What does it mean to be a responsible, mature and wise technological being? Our future lies in seeking real answers to this type of question.
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
One animator combined his skills with paleontological evidence to breathe movement into a dinosaur fossil to eye-catching effect.
Aliens are highly likely to undergo natural selection, shows new research.
Some insects wear gory disguises and macabre masks year round, not just at Halloween.
Recent research suggests that humankind's origins lay outside of Africa. This is the nature of science: a paradigm that cannot be questioned on a regular basis becomes a dogma.
Cladoxylopsid trees were hugely complex and very different to those we have now.
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.
