The East African rift region contains some of the world' s best known hominid fossils and span a time frame which is of major interest for paleoanthropologists. According to several workers the period between 4.5 and 1.0 million years ago was a period of major climatic change. It is not yet sure if these changes in the climate resulted in the diversity of our human ancestors and the origin of the oldest known tools. New research in a wide variety of fields related to the study of human evolution is trying to shed light on this possible relation between climatic change and increased diversity of African fauna.
The  project's main goals:

Date the sediments using all possible tools at hand (magnetostratigraphy, radio-isotopic dating and stratigraphic and geochemical correlation through detailed mapping).

This project with the aims at collecting new data from various locations reported to span the 4.5-1.0 Ma period. The lacustrine sediments from these areas offer ideal distal settings to study climate evolution.

Reconstruct the paleoenvironments.

Collect and correlate fossils to the dated paleoenvironment reconstruction.
What is the age range of the stratigraphy?

Can the climate and tectonic signals be recognised and deciphered in the stratigraphy? 
Furthermore a variety of proxies will be measured for getting a grip on the climatic signal in the sampled sediments.
