This Bird Mimics an Entire Flock to Woo Females

When mating, male lyrebirds reproduce a cacophony of calls usually reserved for when predator is nearby

Juveniles from species of massive carnivorous dinosaurs, such as Tyrannosaurus rex, may have out-competed species that would have otherwise succeeded as medium-sized adults, according to new research.

New Research

Why Medium-Sized Dinosaurs Are Often Missing From the Fossil Record

Study suggests huge carnivores like T. rex may have occupied the ecological roles of medium-sized predators as juveniles

Slime mold in a petri dish. New research finds that slime molds can store memories by changing the diameter of the branching tubes they use to explore their environment, allowing them to keep track of food sources.

New Research

How the Brainless Slime Mold Stores Memories

New research finds the organism can remember the location of food by altering the diameter of the creeping tendrils it uses to explore its surroundings

A statue of Charles Darwin sits in the Natural History Museum in London. The scientist's book 'Descent of Man' was published in 1871.

A Single Altered Gene Can Make Fish Fins More Like Limbs

Researchers find a mutation that offers clues to the ancient sea-to-land transition of vertebrates

These five skulls, which range from an approximately 2.5-million-year-old Australopithecus africanus on the left to an approximately 4,800-year-old Homo sapiens on the right, show changes in the size of the braincase, slope of the face and shape of the brow ridges over just less than half of human evolutionary history.

New Research

Dire Wolves Weren’t Actually Wolves, DNA Analysis Reveals

Ancient DNA extracted from fossils shows the beast split off from Canis lupus and coyotes nearly 6 million years ago

The Volta’s electric eel, Electrophorus voltai, emits the strongest shocks of any animal on Earth. Although these eels were thought to be loners, the species was recently seen hunting in a group.

Shocking Study Finds Electric Eels Hunt Together

The study challenges what researchers know about eels’ supposed loner behavior

If the platypus looks like a mixture of bird and mammal features, it's because it is.

New Research

Platypus Genes Are Just as Odd as the Creature Itself

These egg-laying, lactating animals have genes in common with mammals as well as birds

Oldest-Ever Python Fossil Found in Europe

The 47-million-year-old snake pushes the evolutionary origins of the group back some 20 million years

The pterosaurs were flying reptiles that lived in the age of the dinosaurs. This is an artist's illustration of a member of the genus Pteranodon, which included some of the largest known flying reptiles. .

New Research

Study Reveals Humble Origins of Flying Pterosaurs

Tiny, flightless reptiles called lagerpetids may have given rise to the largest flying animal ever to have lived on Earth

The spectacled tyrant (Hymenops perspicillatus) inhabits harsh, dry deserts, which new research suggests tend to produce new species at a higher rate than lush, biodiverse places like the Amazon.

New Research

Earth’s Harshest Ecosystems May Birth New Species Fastest

A genetic study of nearly 1,300 different birds suggests places with fewer species spit out new ones more frequently than biodiversity hotspots
