There is no need for a large vairiety of outward physical variation in humans. We all survive, particularly in todays world, even the most unhealthy least fit humans survive and reproduce.
That's only true in the industrialized, tehchnologically-advanced parts of the world.
The majority of the world doesn't have access to state of the art health care.
Many, many humans still die, before reproducing, from starvation and preventable illnesses.
