Two fossils found in South Africa provide direct evidence of parental care in extinct pre-mammalian ancestors.
Charles Darwin, who first advanced the theory of evolution, to the chagrin of creationists everywhere.
Rather than castigate those who deny evolution, it is more useful to consider their arguments to help science explain it better
As genes are favored or phased out, human evolution continues.
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, such as
Janjucetus illustrated here, used their sharp teeth to capture and process their prey.
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.
Denali National Park, Alaska.
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?
Tiny hairs cover the bodies of honeybees — including this one dusted in pollen — that allow them to detect molecular “fingerprints” similar to how home security sensors work.
Bees and home security cameras use the same complex techniques to monitor their environments.
Fossilised brittle stars found in Western Australia provide clues about evolution of life underwater.
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.
Gene drives aim to deliberately spread bad genes when invasive species such as mice reproduce.

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.
Hang on, is that a spider floating this way?
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.
She must have had a successful pregnancy.
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?

Larger brains lead to a broader social network.
Pied butcherbirds, such as this one, sing solos, duos and trios.

Is birdsong simply a hard-wired, functional, primitive sound – or could we call it 'music'? Australia's pied butcherbirds show there are surprising overlaps between birds' and humans' musical abilities.
Even if alien life is never discovered, all is not lost.
Simple and inexpensive gene-editing technology such as CRISPR has made the creation of genetically modified organisms much easier. But could nature still keep the upper hand?
Step one is not being afraid to reexamine a site that’s been previously excavated.

A team of archaeologists strived to improve the reproducibility of their results, influencing their choices in the field, in the lab and during data analysis.
Is the evolution of human-like intelligence inevitable, or exceptional?
How can life on Earth help us understand life in space? To answer this question, we compare biological clocks and geological rocks and find that they tick uniformly.
It’s the ability of our immune system to remember past infections, and pass this memory on to our kids, that allows us to survive infectious diseases.
With so many microbes capable of hijacking and destroying us, how are we, as a species, still enduring?
