Fork-tailed drongos have a signature color and pattern on their eggs, which helps them avoid getting duped by African cuckoos.

How These Birds Can Spot Look-Alike 'Imposter' Eggs in Their Nests

Fork-tailed drongos can identify and reject egg forgeries, laid by African cuckoos, with nearly 94 percent accuracy, new research suggests

Male Primate Masturbation May Have Evolved to Prevent STIs

The behavior originated some 40 million years ago to improve breeding success and protect against pathogens, according to a new study

American crocodiles haven't been known to reproduce via parthenogenesis—until now.

Scientists Record the First 'Virgin Birth' in a Crocodile

A female American crocodile living in captivity reproduced without a mate—a finding that suggests dinosaurs might have done the same thing

In an open woodland, Morotopithecus bishopi climbs a tree with an infant on its back and a juvenile below.

Early Apes Lived on Savannas, Not in Forests

Two new studies suggest that 21 million years ago African primates frequented edge habitat and fed on leaves

Hormiphora californensis, also called the California sea gooseberry, is a comb jelly common in California coastal waters.

Comb Jellies May Be the World's Oldest Animal Group

A new study suggests that ancestors of comb jellies, not sponges, were the first to break off from the common ancestor of all animals

Fossils in Wales reveal a glimpse into marine life 462 million years ago. In this illustration based on the new finds, the tall sponge in the foreground is less than one inch in height.

This Trove of Fossils in Wales Is Revealing Secrets of Early Animal Life

Scientists have uncovered 170 species from around 462 million years ago, unveiling surprises about when tiny marine creatures evolved and disappeared

Male California sea lions are polygamous and must fight to defend their territories and their harems.

Why Male California Sea Lions Are Getting Bigger

The “raccoons of the sea” have varied diets, allowing them to grow large to compete for mates

One of the many Edicaran biota fossils within the bounds of Nilpena Ediacara National Park, which is now open in South Australia.

The World's Newest National Park Protects 550-Million-Year-Old Fossils

The 148,000-acre Nilpena Ediacara National Park in South Australia is helping scientists unravel the mysteries of life's evolution on Earth

Lab-raised cockroaches adapted to maintain their glucose-focused sex lives while still avoiding sugary baited traps set by humans.

Zebrafish experience what's known as "emotional contagion" and react when their peers are afraid.

Fish May Sense Each Other's Fear

Zebrafish respond when their peers act afraid, an ability regulated by the same hormone that drives human empathy, a new study shows

A fossil hippo skeleton and associated Oldowan artifacts were exposed at the Nyayanga site.

Who Made the First Stone Tool Kits?

A nearly three-million-year-old butchering site packed with animal bones, stone implements and molars from our early ancestors reignites the debate

A team led by Laurits Skov and Benjamin Peter from the Max Planck Institute for Evolutionary Anthropology sequenced nuclear, mitochondrial and Y-chromosome DNA of 13 Neanderthal individuals. From these sequences, they determined that two of the Neanderthals represent a father-daughter pair and that another two are cousins.
