“Desert Formation and the Emergence of Civilization” Peter B. deMenocal, PhD, Professor and Chair of the Department of Earth and Environmental Sciences and Editor of Earth and Planetary Science Letters at Lamont-Doherty Earth Observatory of Columbia University, will discuss how the natural formation of deserts in East Africa may have been the impetus for human evolution.
The modern-day Sahara was once verdant and lush during the so-called African Humid Period (10,000-5,000 years ago), with abundant wildlife and human settlements. Find out why this “Green Sahara” disappeared 5,000 years ago and how this climate change event led to the first appearance of urban, stratified cultures in Egypt.
