A new study suggests that volcanic eruptions did not lead to the extinction of the dinosaurs, and also demonstrates that Earth's oceans are capable of absorbing large amounts of carbon dioxide—provided it is released gradually ...

Periods of high extinction on Earth, rather than evolutionary adaptations, may have been a key driver in the diversification of amniotes (today's dominant land vertebrates, including reptiles, birds, and mammals), according ...
