This interdisciplinary book interprets early human evolution in the context of the local ecology and specific habitats. It assesses carefully the possible role of climate change in driving early human evolution. Bringing an ecological and biogeographic perspective to recent fossil finds, the book provides a new synthesis of ideas on hominid evolution. It will be a valuable resource for researchers in physical, biological, or paleoanthropology, evolutionary biology or biogeography.
