Environmental theories of African evolution suggest that important evolutionary changes in African mammalian lineages over the last five million years were mediated by changes in African climate. The deep-sea sediment record contains a rich history of these climate changes which, when linked to the fossil record of African faunal evolution (including the emergence of our own genus Homo), allows us to test African climate-evolution ideas.
