Interest in the origins of human populations and their migration routes has increased greatly in recent years. A critical aspect of tracing migration events is dating them. Inspired by the Geographic Population Structure model that can track mutations in DNA that are associated with geography, researchers have developed a new analytic method, the Time Population Structure TPS , that uses mutations to predict time in order to date the ancient DNA. At this point, in its embryonic state, TPS has already shown that its results are very similar to those obtained with traditional radiocarbon dating.

It now seems feasible to reliably date bones up to 55, years. New developments in laser ablation mass spectrometry permit the in situ analysis of U-series isotopes, thus providing a rapid and virtually non-destructive dating method back to about , years. This is of particular importance when used in conjunction with non-destructive ESR analysis.

Fossils are the remains of animals or plants that lived a long time ago. When we think of fossils, the first things that come to mind are the bones of dinosaurs; but a fossil can be anything. Footprints, flowers, even droppings; all of these things can be turned into fossils under the right conditions. A fossil only becomes a fossil when it has reached a certain age. Though there is no one age, a good rule is anything over 10, years old can be considered a fossil.
Lake Turkana has a geologic history that favored the preservation of fossils. Scientists suggest that the lake as it appears today has only been around for the past , years. The current environment around Lake Turkana is very dry.
