David Bercovici, Department of Geology & Geophysics, Yale University Impatient person’s summary: To understand how plate tectonics began we have to first figure out why we have plate tectonics at all, and how to identify a plate tectonic planet if it were passing by.

by David Patterson, George Washington University My research focuses on placing Plio-Pleistocene hominin evolution within a high-resolution ecological context. My dissertation focuses on the Turkana Basin of northern Kenya and Ethiopia, which can be an extremely difficult place to work. However, this region documents many of the most important events in hominin evolution. Thus, it is the… Read More Using animal teeth to reconstruct our ancestors’ environment
