A study has found evidence that the evolution of tree roots over 300 million years ago triggered mass extinction events through the same chemical processes created by pollution in modern oceans and ...

Birds are the only dinosaur lineage that survived until today. About 66 million years ago at the Cretaceous–Paleogene (K–Pg) boundary, a mass extinction event destroyed all non-avian dinosaurs, ...

Properly deciphering the branching pathways of evolution could unlock the history of every component of natural biology.

Human-induced climate change and environmental degradation is causing entire genera to go extinct at rates 35 times higher than what’s been estimated to have occurred in the past one million years. A ...

The publication of An Intimate History of Evolution: The Story of the Huxley Family by Alison Bashford in October 2022 highlights the history of two pivotal figures in the development of modern ...
