Amusing....

[Minimalist]

The modern humans who came out of Africa to originally settle Europe about 40,000 years are presumed to have had dark skin, which is advantageous in sunny latitudes.

And yet, even today in the Congo rain forest...which could be described in many ways but "sunny" would not be one of them... we get this:



those people should have evolved to lighter skin to better absorb what vitamin D gets in through the sunlight which penetrates the tree canopy.

Similarly in New Guinea....



I suspect it is a little more complicated that just sunlight.
