>Comfortably warm temperature throughout the year(22 to 31°C) (can live naked)
>Abundant water and flora and fauna.

Primitive roots of all humans go back to Subsaharan Africa. When early humans left subsaharan africa to colonise rest of the world, they found themselves in a very challenging environment that they had not evolved biological mechanisms due to being a tropical species. The survival was especially harder given the last glacial maximum or ice age which meant even more lethal winters and scarcity than today. Moreover, crossing the barrier of Sahara or Arabian desert was a huge challenge in itself due to harsh desert conditions. So, evolutionary tradeoff was made. Neoteny evolved as a result of natural selection weeding out the unfit resulting in physical abilities being traded off for rise in iq points enabling this more intelligent human species to make clothes, protective houses, tools, to evolve delayed gratification and plan ahead to stockpile wood and food. Eurasians descend from that one tribe of colonisers who left behind their bantu bretheren and safety and comfort of the world they knew.

Bantus represent the most primitive state of early man. They are a time capsule to see what our ancestors and their societies were like. Afro asiatics like afars are not so close to our primal roots and are a result of back migration of Levantine farmers into africa and mixing with Nilotes.
