Evolution

These Male Hummingbirds Evolved Straighter, Sharper Bills So They Could Better Joust for Mates

While female green hermit hummingbirds have curved bills, males’ straighter mouthparts are built for stabbing one another, a new study suggests

For the study, the researchers worked with two adult male macaques that had previously been trained to tap in time with a metronome.

These Monkeys Learned to Tap to the Beat of the Backstreet Boys. Can They Teach Researchers About the Origins of Human Musicality?

Two macaques learned to keep time with various songs, which might point to how humans got their sense of rhythm. But some scientists doubt that the primates’ feat, which required extensive instruction, can give evolutionary clues

The Altamura Man was discovered in a cave in southern Italy in 1993.

Stunningly Well-Preserved Neanderthal Skull Suggests the Species’ Large Noses Weren’t Adapted for the Cold

A new study analyzes the nasal cavity of the “Altamura Man,” a Neanderthal who died between 130,000 and 172,000 years ago

A raccoon peers out from a tree. New research suggests urban raccoons in the United States have shorter snouts than rural raccoons do, a sign of potential domestication.

Urban Raccoons Are Showing Signs of Early Domestication, With Shorter Snouts Than Their Rural Cousins

The shorter faces of these city-dwelling trash bandits offer a telltale sign of domestication and line up with a leading hypothesis about animals that adapt to human-dominated environments, according to a new study

Hyper-realistic reconstructions of Australopithecus afarensis (Lucy foreground, Selam background) by Élisabeth Daynès in the National Museum’s “People and Their Ancestors” exhibition, Prague

Meeting Lucy: How a World-First European Exhibition Brought Visitors Face to Face With the Fossil That ‘Shrinks Time’

Two Australopithecus fossils named Lucy and Selam made a rare trip out of Ethiopia for a 60-day display at the National Museum in Prague

Scientists have identified a new species of non-biting midge—a type of small fly—from 151-million-year-old specimens discovered by an amateur fossil hunter.

This Amateur Fossil Hunter Discovered a 151-Million-Year-Old Insect—and It’s a New Species

Retired teacher Robert Beattie, now 82, has been digging up remnants of the past ever since he was a child

A bee buzzes by a hybrid magenta-and-yellow snapdragon.

Colorful Snapdragons in the Valleys of the Pyrenees Offer a Rare Window Into How Evolution Happens

Studying the ways that magenta and yellow flowers intermingle paints a vibrant picture of how the plants exchange genetic information—and what keeps each color variety unique

An artist's rendition of a group of Nanotyrannus dinosaurs attacking a juvenile T. rex

This Tiny Tyrannosaur Could Settle a Huge Scientific Debate

A new analysis of a fossil unearthed in 2006 provides a fresh line of evidence that a separate tyrannosaur lineage called Nanotyrannus lived alongside the famous T. rex

For two days at the start of monsoon season on the Indian subcontinent, male Asian common toads (right) turn bright yellow, while females (left) stay brown.

For Two Days Each Year, These Drab Brown Toads Turn a Dazzling Neon Yellow—and Scientists Finally Know Why

When monsoon rains begin to fall on the Indian subcontinent, Asian common toads congregate at temporary puddles for a frenzied, two-day mating spree

Psilocybe cubensis, a mushroom that produces the psychoactive compound psilocybin.

Magic Mushrooms Evolved Psilocybin Not Once, but Twice

Two different types of mushroom evolved the same psychedelic compound in completely unrelated ways, a recent study finds

To capture snake strikes on video, scientists put medical gel on a stick and warmed it to mimic the body temperature of a mammal. Then, they waited for the snakes to attack.

Slow-Motion Videos Reveal What Really Happens When Snakes Bite

Different snakes put their own spin on striking their prey. Scientists captured the powerful attacks on camera

Cameras captured nematodes attaching themselves to electrically charged fruit flies. 

These Parasitic Worms Use Static Electricity to Hitch a Ride on Flies

The tiny experiment yielded big results, showing how nematodes hop onto fruit fly hosts

Researchers collected images of lizards with missing limbs from experts around the world. Pictured here: an American green anole.

These ‘Pirate Lizards’ Thrive With Three Legs

A new study finds that many lizards with missing limbs fare surprisingly well despite their impairment

The first hand and foot fossils clearly linked to Paranthropus boisei reveal the human relative could have handled stone tools.

Cool Finds

Discovery of First Fossil Hand Linked to P. Boisei Suggests the Bygone Human Relative Could Have Used Tools

A new study sheds light on the enduring mystery of whether our ancient cousins were toolmakers, too

Camels evolved into a range of shapes and sizes, including small forms like these Stenomylus on display at the American Museum of Natural History.

Meet the Extinct Camels of North America, From Ice Age Giants to Sheep-Size Runners

Largely outshone by fossils of horses, the earliest camels are getting another look from scientists determined to sort out the relationships and adaptations of these “absolutely bonkers” herbivores

A superb fairy-wren calls to a Horsfield's bronze-cuckoo. Brood parasites like cuckoos lay eggs in other birds' nests and leave them behind for the host birds to raise.

Birds Make an Alarm Call That Spans Species and Continents—and May Offer Insight Into the Evolution of Human Language

More than 20 species make a nearly identical noise to warn nearby birds of brood parasites, a behavior that bridges the “sharp division between animal communication systems and human language”

Artist's reconstruction of the ancient Macromyzon siluricus leech

Leeches May Be 200 Million Years Older Than We Thought—and Haven’t Always Sucked Blood

A Wisconsin fossil find suggests leeches once ate their prey whole or simply sucked up their innards

New Research

To Hide From Predators, Some Animals Camouflage Into Their Surroundings, While Others Display Bright Colors as a Warning. What Keeps Them Safest?

While many circumstances factor into the calculation, researchers found in a new study that local predators, not appearance alone, had the greatest impact on a color strategy’s success

Chimpanzees in Uganda's Kibale National Park love eating figs, which scientists found had the highest level of alcohol at the site.

Chimps Consume the Equivalent of 2.5 Alcoholic Drinks per Day by Eating Fermented Fruit, Study Finds

Scientists report that chimpanzees consume about 14 grams of alcohol daily and suggest the result might help explain humans’ interest in booze

Paleontologists Discover Earliest Known Dome-Headed Dinosaur in Excellent Condition, Shedding Light on Its Mysterious Anatomy

Most of what researchers previously knew about the iconic Cretaceous dinosaurs came from their domed heads, which endured better than the rest of their skeletons
