The Fall 2015 Origins Field School is now more than halfway through! We are currently in our fourth module Human Origins and our last module at TBI Ileret facilities (we will spend another 2 weeks at the Turkwel field station). Starting this week, students are going to learn how we are different from our ape-like ancestors and how we have become who we are. Our instructor of this module is Dr. Jason Lewis currently working at both TBI and Stony Brook University. Dr. Lewis has been working in the Turkana Basin for several years and has taught the Human Origins module several times. He is also the co-director of the West Turkana Archaeological Project (WTAP). Dr. Lewis and collaborators of WTAP announced the discovery of the earliest known stone tools about 3.3 million years ago.
