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 ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of studies ...

An updated evolutionary model shows that living systems evolve in a split-and-hit-the-gas dynamic, where new lineages appear in sudden bursts rather than during a long marathon of gradual changes.

“Terrible Lizards”—That’s the literal translation of the term Dinosauria, coined by Sir Richard Owen in the 19th century to describe the colossal bones early paleontologists were unearthing. For a ...

New research headed by scientists at the Centre for Genomic Regulation (CRG) has demonstrated how the three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary ...

DNA samples from one of the world’s largest and oldest plants — a quaking aspen tree (Populus tremuloides) in Utah called Pando — have helped researchers to determine its age and revealed clues about ...

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, ...

Sitting in my campsite at Goblin Valley State Park, I saw an antelope ground squirrel standing erect on its back feet, which I found amusing. I soon found that this was a common posture evoked by ...
