Actually, it's the variation that promotes evolution.
There's typically far less genetic deviation between two random people selected on opposite sides of the world than there'd be between 2 chimps in the same tribe.
The common reasoning for that is because of multiple genetic bottlenecks in humanity's past via natural disasters that brought us to the edge of extinction and, thus, limited the resulting gene pool that matriculated from the survivors.
I think if medicine would be said to do anything, it'd be to promote evolution because it'd keep the gene pool even more varied for the next bottleneck by keeping more individuals alive, thus giving our species greater genetic variation.
