    One factor that we fail to mention is the role of geography in explaining average IQ differences between the so-called races. Scientist generally agree that modern day humans originate from Africa, and then later gradually migrated to other parts of the world. Geographically speaking, when humans arrived in parts of Europe and Asia, the environment provided them with clear advantages that might have led to these IQ discrepancies. Its not so much the environment, but its the culture cultivated from the environment.
