Bufoceratias wedli, a deep-sea anglerfish

Bizarre Sex Helped Anglerfish Diversify and Dominate the Deep Sea, Study Suggests

Some of these fish perform obligate parasitism, in which males attach to—and then fuse bodies with—the much-larger females

The sympathetic nervous system was thought to have evolved with jawed vertebrates. But lampreys—jawless, parasitic fish that suck out the blood of their hosts—have a simple one, per recent research.

Eerie Lampreys Hint at the Origins of Our 'Fight-or-Flight' Response and Sympathetic Nervous System

The jawless, parasitic fish largely haven't changed over the last 340 million years, but they might be better sources for studying our own evolution than thought, a recent study suggests

Scientists trained three carrion crows to produce one, two, three or four vocalizations based on various visual or auditory cues.

Crows Can 'Count' Up to Four Like Human Toddlers, Study Suggests

Three carrion crows engaged in a simplified version of counting when prompted, and the birds showed signs of planning out their responses

African wild dogs might use facial expressions to communicate with each other as they hunt in packs on the savanna.

Wild Dogs Have Muscles for 'Puppy Eyes,' Suggesting the Cute Expression Did Not Evolve Just for Humans

African wild dogs have the same well-developed eye muscles that domestic dogs use to make their signature pleading faces, a recent study finds

German cockroaches took advantage of human globalization to spread all over the world.

DNA Reveals How German Cockroaches Came to Dominate the World

A new paper looks at the genes of the most common cockroach species, tracing its historical journey alongside humans, from Asia to the Middle East, Europe and beyond

Baobab trees can reach 100 feet tall, and they support entire ecosystems and communities with their large structures and natural resources.

Scientists Uncover the Ancient Origins of Baobab Trees in Genetic Study

The trees originated in Madagascar 21 million years ago but later traveled long distances by way of ocean currents, according to new research

Latyr Sy, a Senegalese percussionist and singer, was one of 75 researchers who played music for the study.

Why Do Humans Sing? Traditional Music in 55 Languages Reveals Patterns and Telling Similarities

In a global study, scientists recorded themselves singing and playing music from their own cultures to examine the evolution of song

An artist's rendering of a feathered dinosuar in the snow. Feathers would have allowed dinosaurs, ancestors of birds, to trap their body heat in cold climates.

Some Dinosaurs Evolved to Be Warm-Blooded 180 Million Years Ago, Study Suggests

Researchers studied the geographic distribution of dinosaurs to draw conclusions about whether they could regulate their internal temperatures

An illustration of some of the underwater creatures that lived during the Ediacaran Period, roughly 635 million to 541 million years ago.

Earth's Magnetic Field Nearly Collapsed 600 Million Years Ago. Then, Weird and Complex Life Evolved

A new study suggests more solar radiation reached Earth while the magnetic field weakened, leading to a rise in oxygen that drove an explosion of multicellular organisms during the Ediacaran Period

Dice snakes feigned their own deaths with a variety of mechanisms, including filling their mouths with blood (shown right).

Dice Snakes Fake Their Own Deaths With Gory, Poop-Filled Theatrics

When attacked by a predator, the reptiles can play dead with convincing detail, employing blood and feces for the show

Close-up showing the Archaeopteryx fossil’s skull, neck, spine, rib cage and wing bones. The fossil will go on view at Chicago's Field Museum on May 7.

Chicago Museum Unveils the 'Most Important Fossil Ever Discovered': the Feathered Dinosaur Archaeopteryx

Archaeopteryx provided the missing link between dinosaurs and the avians of today, serving as critical evidence for Charles Darwin’s theory of evolution

In more than 20 years of field research, Rakus is the first orangutan to be observed using a medicinal plant to treat wounds.

In a First, an Orangutan Healed His Own Wound Using a Known Medicinal Plant

The primate named Rakus chewed up yellow root and applied it to an open facial wound, closing the sore within days

Scientists are at odds about how intelligent T. rex was.

How Intelligent Was T. Rex? Scientists Suggest the Dinosaurs Were Like 'Smart, Giant Crocodiles'

A new paper refutes the idea that T. rex was as brainy as a baboon, furthering the debate on the extinct reptile's intellect

An artist's illustration of two Ptychodus sharks eating sea turtles and ammonites in open water.

Paleontologists Unravel Secrets of 'Enigmatic' 33-Foot Prehistoric Shark After Fossil Discovery
