Single Origin

fossil record shows that from the earliest times, Africa was consistently the center from which new lineages of hom-inids sprang. Clearly, interesting evolutionary developments occurred in both Europe and eastern Asia, but they involved populations that were not only derived from but also eventually supplanted by emigrants from Africa. In Africa our lineage was born, and ever since its hominids were first emancipated from the forest edges, that continent has pumped out successive waves of emigrants to all parts of the Old World. What we see in the human fossil record as it stands today is without doubt a shadowy reflection at best of what must have been a complex sequence of events.
