I think that is a valid question, Karma2Grace. The span of time in which evolutionists assert that man developed from the first primate is very small, at least in terms of the history of Earth. Yet there are many many species which supposedly developed between that time and when the first humans appeared. The human evolution chain is much more complicated than that which has been found in most species.(Just one of many examples of how man is an anomaly within the multiple theories of evolution) This means there must have been at least some significant changes in thousand year periods. Therefore I would expect something significant to have changed in recorded history, at least one alteration. Especially considering that humans have remained isolated from other humans in different climates for many years. In other species we see significant differences in species in different areas. This is not so with humans. Other than skin color, facial structure, or build there are no significant differences among humans.
