2 million years of climate shaped human evolution

A large-scale climate simulation combined with fossil evidence shows how shifts in temperature and rainfall guided human migration and evolution. Changes driven by Earth’s orbital cycles altered ...
Scientists have uncovered a surprising mechanism that may explain how Earth cooled dramatically after the age of dinosaurs.
The cycling of water within Earth's interior regulates plate tectonics, volcanism, ocean volume, and climate stability, ...
“The closer it is to the sun, the more a planet becomes dominated by the sun’s gravity,” Kane said. “Because Mars is farther ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. An international team of researchers investigated how Earth’s ...
Our species likes it cold. Homo sapiens evolved in — and still inhabits — one of Earth’s rare and fragile ice ages, periods distinguished not by an abundance of saber-toothed cats and woolly mammoths ...
The Cambrian Explosion in which life on Earth underwent massive diversification was likely triggered by eccentricities in Earth’s orbit around our Sun. Or so say the authors of a new paper just ...
