The Laboratory of Paleolimnology at the University of Arizona is leading a $10 million dollar investigation, involving over 50 scientists from 8 countries, using sediment drill cores from lake deposits to understand the paleoenvironmental and paleoclimatic context of human origins. Through the collection of specifically targeted drill cores from ancient lake deposits in Kenya and Ethiopia we hope to transform our understanding of how environmental change and variabilitiy may have impacted the evolution, diversification and extinction of our ancestors and near relatives. Details about this project can be found at our project Facebook page (see Hominin Sites and Paleolakes Drilling Project-HSPDP), the HSPDP project website (http://hspdp.asu.edu) or the International Continental Drilling Program Site (http://www.icdp-online.org/front_content.php?idcat=1225) for more information.
