A forgotten fossil discovered in a museum drawer after more than 60 years is challenging assumptions about animal evolution.

Phylogenomic analysis harnesses genome-scale data sets to reconstruct the deep branches of the animal tree of life, resolving longstanding debates about the relationships among major lineages such as ...

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a study in Nature Communications. It is the first time ...

A huge and beautifully preserved suite of fossils discovered in China has cast doubt on the idea that complex life flourished dramatically during a rapid burst of evolution known as the Cambrian ...

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, ...

The dinosaur changing how scientists think about evolution is not a towering predator or a massive long-necked giant. It’s a creature barely half a meter long, light enough to tuck under one arm.

People typically think about evolution as a linear process where, within a species, the classic adage of “survival of the fittest” is constantly at play. New DNA mutations arise and get passed from ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...

Researchers from the Canadian Museum of Nature (CMN) have identified a new species of rhino that once roamed Canada's High Arctic 23 million years ago. The extinct rhinoceros, described in the journal ...
