Mohave rattlesnakes and Merriam kangaroo rats are currently embroiled in an evolutionary arms race, pitting wily predator against fast-acting prey. Dramatic high-speed video shows how quick and creative snakes need to be to launch an attack — and how rodents still manage to evade capture.

Although we call erections "boners", anyone who has basic familiarity with human anatomy knows our slang deceives us — for unlike most mammals, men have no penis bones. For decades scientists have wondered, "Why no penis bone?" A new study published in Proceedings of the Royal Society might finally answer the mystery of what killed the penis bone: Monogamy.

A new study from the University of Vienna, Austria, suggests that Cesarean sections are changing the trajectory of human evolution, altering physical characteristics in both mothers and babies. Trouble is, the researchers presented virtually no empirical evidence to support their extraordinary claim, and the credulous media simply took it at face-value.

The Arctic is a stunning 20°C warmer than average for this time of year. This is really bad news for layers of sea ice that regulate Earth's climate, and land-based ice sheets that keep sea levels where they should be. As we stare down a US presidency where the transition leader for the Environmental Protection Agency is a climate denier, it's easy to wonder whether it's too late to prevent climate change from destroying our civilisation.

As Charles Darwin showed nearly 150 years ago, species can adapt to changing environmental conditions through the trial-and-error process of natural selection. A discouraging new study shows that climate change is happening too fast for evolution to keep up, placing countless plant and animal species at risk.

The island of Giraglia is a windswept pile of rocks that sits within eyeshot of the northern tip of Corsica in the Mediterranean sea. Humans never lived here, but two types of geckos do. One runs free; the other's a prisoner — and their story may help unravel a longstanding evolutionary mystery.

Video: The trailer for Lucile Hadzihalilovic's Evolution begins with a young boy discovering a dead body, and that's not even in the top 10 of the creepiest things happening in it. There's the fact that the island seems to be populated solely by other young boys and very stern older women. There's a lot of medical equipment around. And then... there's the starfish. Look, just watch the trailer.

Centuries-old theories surrounding human height as it correlates to evolution have stated two things: Those closer to the equator were more linear and longer, while people who lived closer to the poles were wider and shorter, but generally bigger. This is according to Allen's Rule and Bergmann's Rule, which were both proposed during the 19th century.

Video: The Joker is easily one of the best villains in film and TV (and obviously, comic book) history, but who is the best Joker? Jack Nicholson combined the mischievous campiness of the character with the deranged thirst for violence. Heath Ledger's The Dark Knight Joker is somehow just as iconic as Nicholson and fit Christopher Nolan's Gotham perfectly. And Mark Hamill has basically become the standard-bearer of the Joker through his work in the animated Batman series.
