Abstract: Questions surrounding the origins and development of our species have been the subject of much research and speculation in disciplines ranging from Biology to Archeology. The greatest challenge for studies on origins is probably that of "deep time". For biologists, geologists, physicists and even historians dealing with deep time, the window gets progressively dimmer the further we look back, as data become more sparse and less reliable. The quality and quantity of information emerging from deep time is, however, rapidly improving. This is especially the case for the fossil record where recent scientific discoveries indicate the presence of life on Earth in very early stages of Earth history and a succession of major, even cataclysmic, climatic events that reset the path of geological and biological development on Earth.
