Скачать или смотреть Climate Change and Human Evolution by Dr. Naomi Levin, University of Michigan

a behind the scenes look at using geology and geochemistry to understand our origins:
Linking human evolution to environmental change is nearly as old as the concept of evolution. As soon as fossils of early humans were identified, questions were posed about how they fit into a story of changing vegetation and climate. Did human evolution occur amidst a backdrop of (or in part because of) expanding grasses and the development of hot, arid environments? Answering these questions rigorously requires many different types of data on a range of spatial and temporal scales. The collective communities of paleoanthropologists, paleontologists, archaeologists, geologists, ecologists, and climate scientists have made huge strides in addressing these questions in the past 25 years.
