Hominids - Prehistoric Hunters from the Dawn of Time


Robert D. Morritt




          Radiometric dating indicates that the Earth is about 4.570 billion years old. Earth's past has been organized into various units according to events which took place in each period. Different spans of time on the time scale are usually delimited by major geological or paleontological events, such as mass extinctions. For example, the boundary between the Cretaceous period and the Paleocene period is defined by the Cretaceous-Tertiary extinction event, which marked the demise of the dinosaurs and of many marine species. Older periods that predate the reliable fossil record are defined by absolute age. Innovations in nuclear technology have revised opinions drastically over the last two decades with the interesting concept (in the Mediterranean) of Neolithic peoples co-existing with modern man. Within these pages we consider different opinions of geographic 'genesis' the location of 'missing links' and follow the path of mankind from the cradle of civilization.
