Study Signals Change in How Scientists Calculate Ancient Diets
Scientists have long determined what extinct animals ate by analyzing carbon isotopes locked inside their fossil teeth. But a new study shows that in many cases, they may be plugging the wrong numbers into their equations. The findings may change some views of how mammals, including us, evolved.

Ancient Humans Left Africa to Escape Drying Climate, Says Study
Ancient humans migrated out of Africa to escape a drying climate, says a new study—a finding that contradicts previous suggestions that ancient people were able to leave because a then-wet climate allowed them to cross the generally arid Horn of Africa and Middle East.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
