Very pleased to see our paper published online at Climate of the Past: cp.copernicus.org/articles/21/...

We present model-data comparisons of Late Quaternary climate across the Northern Hemisphere, showing that increasing model resolution has little net effect on coherence with pollen proxies 😊

Around 70,000 years ago, our ancestors in Africa began exploiting different habitats.

Flexibility to survive in deserts to rainforests enabled their successful spread β€˜Out of Africa’.

When Humans Learned to Live Everywhere About 70,000 years ago in Africa, humans expanded into more extreme environments, a new study finds, setting the stage for our global migration.

About 70,000 years ago, a new study suggests, our species learned to live just about anywhere. Later, that ability helped our ancestors expand from Africa across the world. Here’s my story on the human niche [Gift link] nyti.ms/3ZBc7ID
