The occurrence of a phylogenetic signal for lethal violence in mammals enables the phylogenetic inference of lethal violence in humans. We used ancestral-state estimation methods that infer the ...

Imagine tracing your family tree not just to distant ancestors, but to creatures that once swam in primordial seas and hopped along muddy riverbanks. The connection is more than poetic—it’s written in ...

SARS-CoV-2 is a beta-coronavirus that is thought to be originally bat-borne before jumping to humans to cause the COVID-19 pandemic.

Dogs have been in the Americas for more than 10,000 years. They were already domesticated when they came from Eurasia with ...

The extinction of hundreds of bird species caused by humans over the last 130,000 years has led to substantial reductions in avian functional diversity – a measure of the range of different ...

By sequencing an enormous amount of data, a group of hundreds of researchers has gained new insights into how flowers evolved on Earth.

A new fossil and DNA analysis traces how dozens of sloth species responded to climate shifts and humans. Just two small tree-dwelling sloths remain today.

The researchers found recombination most often shows up on the COVID-19 phylogenetic tree in the form of "long branches," making it appear that several mutations happened sequentially, which is ...

Rings within the trunks of ancient fossilized trees showed evidence for the most powerful solar storm in history, 10 times stonger than the Carrington Event.

Beard left it to Rust to conduct the morphological analysis that tied Ekgmowechashala and its cousin Palaeohodites from China in a phylogenetic tree to establish their evolutionary relationships.
