Scientists have found that periods of high extinction on Earth have been the drivers of the diversification of amniotes, which include today's land vertebrates, such as reptiles, birds, and mammals.
Researchers have sequenced the genomes of two species of small water creatures called acorn worms, and have found that humans may have more in common with them than first thought.
Astronomers may have spotted a baby planet being born around a young star. The new findings may reveal a bit more about planet formation outside of our own galaxy.
Researchers have discovered a 170-million-year-old mouse-sized fossil from the Middle Jurassic, which is revealing new information about the evolution of molar teeth in modern mammals.
Paleontologists have uncovered a new species of duck-billed dinosaur with a surprising crest.
There may be an arms race occurring among venomous animals. Scientists have made new discoveries about how animal venom evolves, and have found that there's a "two-speed" evolution of animal venom.
Scientists have found that about 550 million years ago, tiny marine creatures had complex skeletons, which suggests that the earliest complex animals lived millions of years earlier than previously known.
A fossil sea urchin is actually the oldest ever found. In fact, it pushes back a fork in its family tree by a staggering 10 million years.
A team of researchers have discovered an extinct species of apes known as 'Pliobates cataloniae' which existed 11.6 million years ago. This new finding reveals new information about humans' ancestors, and the evolutionary split between great apes and small apes.
The world's oldest DNA sequences may reveal the most ancient animal ancestors.
After studying individual chickens that were part of a long-term pedigree, researchers found two mutations that had occurred in the mitochondrial genomes of the birds after only 50 years.
Researchers have discovered a dinosaur specimen with well preserved tail feathers and skin tissues. This new study links some modern birds to dinosaurs, since they share similar evolutionary traits, according to researchers.
