For almost 200 years it has been believed that the placental mammals, and the related marsupials, had originated in the northern hemisphere

The missing link isn’t a not-yet-discovered fossil, after all. It’s a tiny, self-replicating globule called a coacervate droplet.

Humans appear to have the genes for a full coat of body hair, but evolution has disabled them, scientists at University of Utah report.

Diverse microbial life existed on Earth at least 3.75 billion years ago, suggests a new study that challenges the view of when life began.

One question asked frequently by undergraduates to Kevin Padian stuck with him: Why are the arms of Tyrannosaurus rex so ridiculously short.

Researchers have brought the first evidence of nonrandom mutation in human genes, challenging a core assumption at the heart of evolution.

Modern humans evolutionarily split from our chimpanzee ancestors nearly 7 million years ago, yet we are continuing to evolve.

Climate change, rather than competition, played a key role in the rise of dinosaurs through the Late Triassic and Early Jurassic periods.

Australia, home to the most unusual animal species on the planet, can now lay claim to being the wellspring of modern mammal evolution.

Earth is currently in the midst of a mass extinction, losing thousands of species each year, new UC Riverside research suggests.

The use of ancient DNA, including samples of human remains around 45,000 years old, has shed light on a previously unknown aspect of humans

The green world that we live in would not have been possible without hidden changes to the plant body over the last 400 million years.

Chemical evolution was first proposed in the 1920s as the idea that life first originated with the formation of macromolecules.

A fossil discovery from Scotland has provided new information on the early evolution of lizards, during the time of the dinosaurs.

DNA from victims and survivors of the Black Death pandemic has identified key genetic differences that determined who lived and who died.

Ancient genomes of 13 Neandertals provide a rare snapshot of their community and social organization over hundreds of thousands of years.

These types of gases are made when organisms add a carbon and three hydrogen atoms to an undesirable chemical element.
