August 2018 rolled in with a bang, literally, as explosions rocked Caracas, Venezuela on Saturday during a speech by President Nicolas Maduro—and government officials later said bomb-carrying drones were to blame. If the accounts of an attempted assassination using unmanned aerial vehicles is confirmed, the New York…

More than 500 different shark species roam Earth’s oceans: from zippy little cookie-cutter sharks, to the iconic great white, to nightmarish goblin sharks, to 25-foot-long, filter-feeding basking sharks. And it seems that the current equilibrium of shark species we see today arose after the Cretaceous–Paleogene mass…

The aye-aye is about as ridiculous looking as a primate can get: beady yellow eyes, bat-like ears, and hands like horrible spiders. But perhaps its most interesting feature is its teeth.

In the 1980s, scientists learned that all humans living today are descended from a woman, dubbed “Mitochondrial Eve,” who lived in Africa between 150,000 to 200,000 years ago. This discovery, along with other evidence, suggested humans evolved from a single ancestral population—an interpretation that is not standing…

The evolutionary journey of how dogs came to occupy millions of human living rooms is a complicated one, filled with detours and false starts. A new study out Thursday in Science seems to better illuminate one of these detours. It suggests the first domesticated dogs to come to the Americas were brought by humans…

A re-analysis of a three-million-year-old fossil suggests Australopithecus afarensis, an early hominid, had children who were as capable on two feet as they were in the trees—an important discovery that’s shedding new light on this critical stage in hominid evolution.

Imagine that during our evolutionary history, we could not turn our heads up or down. How might our vision have evolved differently from the two frontal, mobile eyes we have today?

DNA from a 22,000-year-old fossilized panda skull suggests an entirely separate lineage of giant pandas once roamed the area that is now southern China.

Fifty million years after humanity’s extinction, the world has once more grown wild. In the forests of North America, the deer-like descendants of rabbits flee attacks by large predatory rats. Giant antelope and striding baboons more reminiscent of dinosaurs roam Africa’s savannas.

It’s nice to think we’re part of something bigger. And we are, really—in a cosmic, evolutionary sense.

When separates us from the animals? Is it the burden of consciousness, the terror of knowing that one day we will die, along with everyone we’ve ever loved? Or is it our big weird asses?

Modern filter-feeding baleen whales use comb-like structures in their mouths to scoop up large volumes of itsy-bitsy animals and microorganisms. But as new research reveals, their ancestors were remarkably different, featuring sharp teeth that they used to attack prey.

In a scientific first, researchers have used an MRI scanner to study the brains of Nile crocodiles. Sounds weird—and even a bit dangerous—but the experiment is revealing new insights into the evolution of brains and how mammals and birds acquired the capacity to comprehend complex sounds.

Scientists in Israel have observed a strange behavior among brown widow spiders: When given the choice, the males of this species prefer to have sex with older females even though they’re less likely to bear offspring. More problematically, these older females are also more inclined to devour their partners after…

The scientists who discovered the strange feature are calling it a “lachrymal saber,” but for the predators who dare to mess with this type of stonefish, the unique switchblade just means trouble.
