The evidence indicates that Homo erectus (essentially man as we now know him), Homo habilis and Zinjanthropus were broadly contemporary. Hence any attempt to derive H. erectus from either of the other forms runs contrary to the paleontological record. Aside from the interesting Olduvai fossils in Africa, the geographical distribution of fossil human remains indicates they are marginal representations of a widespread dispersion of people from a single multiplying population in the Middle East. All were of one basic stock–the Hamitic family of Genesis 10. The most degraded specimens are from the least hospitable areas where they suffered physical degeneration as a consequence of the circumstances in which they were forced to live. The extraordinary physical variability of fossil men results from the fact that they were members of small, isolated inbred populations. Later the Indo-Europeans (Japhethites) displaced or overwhelmed the original Hamitic pioneer stock. All trace back to the three sons of Noah.
