Changes in our environment can reveal previously hidden mutations in our DNA with potentially good and bad consequences.
Heracles inexpectatus on the forest floor, with three small wrens foraging at its feet.

The newly discovered Heracles inexpectatus stood nearly a metre tall. And its fossil bones sat undiscovered on a museum shelf for more than a decade before its hefty status was finally appreciated.
En garde!

New evidence boosts the idea that species with males who compete for mates adapt faster to changing circumstances.
It’s OK, I’m a filter feeder: Whale shark off Indonesia.

Media coverage of sharks often exaggerates risks to people, but more than 500 shark species have never been known to attack humans, and there’s lots to learn about them.

The ethnic and religious composition of our societies is increasing rapidly. How will these changes impact our quality of life?

Scrapping the idea of a species is an extreme idea – but perhaps a good one.
The teeth in these Australopithecus africanus skulls contain important evidence about the nutrition of these individuals as they grew up.

A new study shows the enigmatic hominin species Australopithecus africanus may have breastfed young for around 5-6 years – a very costly practice for the mother.
The ancestral population of modern humans appears to have split as it moved across Asia.

New research outlines how the ancestors of modern humans interbred with several archaic human groups on the passage from Africa to Australia.

A shift in climate, along with other environmental disruptions and the invasion of competitors and new predators all likely played an important role in reshaping ancient elephants’ brains.
Jumping spiders, like this one, usually have eight eyes: two very large front eyes to get a clear, colour image and judge distance, and extra side eyes to detect when something is moving.

Human eyes are very complex and are good at doing many jobs at once, while spiders have different sorts of eyes that do different jobs.
Some lizards such as geckos can self-amputate their tails when threatened - these limbs can keep twitching for up to 30 minutes, creating a distraction and allowing the lizard to escape.

Why do some animals amputate their own limbs? Turns out, there’s a whole bunch of reasons why this strategy has evolved.

Researchers were surprised to learn that in 38 countries, lost wallets with higher sums of money were returned more often than those with smaller amounts.
Ladybirds are insects with a hard outer shell, just like beetles.

Ladybirds do not have tails because they have no backbones.

Modern science clashes with the idea that the rise of Homo Sapiens was a fluke.

A large number of young people are reluctant to accept evolution. How we teach the topic might be a key reason why.
Antibiotic resistance can spread between microbes within hours.

Resistance to antibiotics is not a new trait, and it is impossible to prevent. But it is possible to avoid its spread.
Naked mole-rats feel no pain when exposed to acid or capsaicin.

With the opioid crisis there is no doubt that physicians need safer, nonaddictive pain killers. Now new insights on how to create these are coming from an unlikely source: the naked mole rat.
