That entire premise falls apart when you let a person with a different skin color enter the room of children that have never seen that skin color before. There are even videos of it where children scream in horror.
And humans didn't just evolve from one central location. They evolved in parallel on an entire continent. They then also mixed with different subspecies.

Are those children babies or older? Children are taught to fear the other at an extremely young age. I’d like to see a similar study of newborns seeing a newborn of color for the first time.
