Scientists believe the Caudipteryx may hold the secret to explaining how animals first learned how to fly. The running gait of this early dinosaur caused its wings to involuntarily flap, which may have been a precursor to flight.

A new study has revealed marvelous insights on the skull of the ancient coelacanth fish, which is known as the 'oldest living fossil.' The findings offer a deeper understanding on skull evolution of vertebrates and other animals.

Scientists in the United States may have found an explanation as to how mammals ended up with diverse sets of arms. They believe the animals already had this trait some 30 million years before the earliest dinosaurs even existed.

Two different lineages of common ravens that have separated and evolved from each other millions of years ago merged again as one. This evolutionary process is known as speciation reversal or lineage fusion.

Among the 20,000 fossils uncovered at Burgess Shale, one was found to contain soft tissue belonging to a 2-centimeter worm. It gave scientists strong evidence that in their early evolutionary stages, worms had a far different appearance.

Scientists have discovered the remains of a massive crocodile-like creature with T-rex-sized teeth in Madagascar. The new discovery may help uncover the mystery behind the 74-million-year-long gap in the evolutionary history of crocodiles.

Using genome sequencing, scientists have identified various genetic factors that give seahorses their unique body structure. These include genes that allow males to carry and give birth to their offspring in their brood pouch.

The atlantic killifish has evolved to be 8,000 times more resilient to toxic waste than other species of fish. High levels of genetic variation allow the fish to adapt to industrial pollutants that would normally kill them.

Evolutionary biologists have long wondered whether mammalian hair, avian feathers and reptilian scales have some sort of evolutionary link. A new study in Switzerland may shed light on the matter.

Garter snakes and some snake species today are only able to eat toxic newts because their ancestors evolved. What did ancient snakes develop to survive?

Why the long neck? Because of unique evolutionary adaptations, giraffes have reached such great heights. Researchers determine the genes responsible for this development.

A group of European and Brazilian paleontologists achieved two feats. They did not only uncover the first-ever fossilized heart in a marine vertebrate, but they may also help fill the gap of the species’ evolution.

Although most species were wiped out by an extreme extinction event millions of years ago, the therapsid Lystrosaurus survived. How did they do it? By changing their breeding behavior.

A new study hypothesized that sperm whales may be capable of ramming, making 'Moby-Dick' less fictitious. However, is their unique head truly designed for ramming?

An international team of scientists has discovered the remains of a new tyrannosaur that could help provide more insights as to how these dinosaurs were able to become such massive creatures. The Timurlengia euotica showed traits that were similar to both the smaller tyrannosauroid and the larger tyrannosaurus rex.

Researchers from Australia and the United States have discovered four new species of purple sock-like creatures that belong to the genus Xenoturbella. This allowed them to identify the placement of the creatures in animal tree of life.

The smaller the chameleon, the mightier its tongue, study finds. To capture an insect meal, a chameleon's tongue out-accelerates and out-powers that of any other reptile, bird or mammal based on body size and muscle mass.

A new study revealed that the Myxozoa are actually tiny jellyfish that went through degeneration. Scientists said the discovery could change the way we understand the evolution of animals.

A team of scientists in Australia have found that crocodiles engage in a sleeping behavior known as unihemispheric sleep wherein they keep a watchful eye open during rest. Other members of the animal kingdom are also known to carry out unusual sleep behaviors that may have evolved out of necessity.

The reason behind the giraffe's long neck baffled the scientific community for years. In a new study, scientists found that the giraffe's vertebrae stretched in several stages a few million years apart.

Whether an animal is hunter or the hunted is reflected in the evolution of its eyes, researchers find. Pupil shape identifies a creature's ecological niche, they say.

Scientists at the University of Glasgow have found that pressure from intensive fishing could potentially lead to evolutionary changes within wild fish populations, making them more adept at avoiding capture through conventional fish catching techniques such as trawling.

Scientists from the University of Cambridge and the University of Leicester have studied the development of the razor-sharp teeth of penis worms in order to create a better system of identifying fossils using dental structures.

Chicks of a tropical bird species make themselves safe in their nests by mimicking the color and movement of a poisonous caterpillar, naturalists find. It's an evolutionary trick that lets a vulnerable species appear to be a protected one, they explain.

Weird "zombie worms" of the deep ocean get even weirder with discovery of new species. Males of the new species have experienced "reverse" evolution, researchers say.

When opportunity knocks, non-human primates take advantage of it and learn tool use, researchers say. The local environment provides both the opportunity and the reason for tool use, they suggest.

Hummingbirds may have evolved long, sharp beaks as weapons, rather than just for getting at nectar in flowers, study find. Males competing for mates use their sharp beaks as swords, researchers say.
