Our colleagues on the project are from the UK, Ethiopia, Germany and the US. Some are busy working out how old each bit of the sediment core is, e.g. using radiocarbon dating at the top and dating volcanic ash layers towards the bottom. Others are looking at changes in the type of algae found down the sediment core, to look at changes in how fresh or salty the lake water was over time. Some are taking the reconstructed climate changes and relating them to changes in human history. We want to establish what the climate was like when our species, Homo sapiens, evolved and then spread out of Africa. Some people have suggested that when climate changes from more variable to more stable, that can lead to movements of populations, but we want to test that hypothesis.
