Why did Europeans evolve with blond, red, brown, black hair when it should have just been one lighter color hair they evolved with?Why did Europeans evolve with different shades of hair color?
Places like England, Norway and Sweden were more isolated that the rest of the world (due to the sea and land barriers). Through natural selection people with blonde/red hair survived and went on to breed (maybe they were considered more attractive). Since they lived in isolated places these genes spread across a large area without being effected by other genes. So now it is more common to have blonde/red hair if you live in the UK and Northern Europe.Why did Europeans evolve with different shades of hair color?
Most likely genetic drift or sexual selection
Scandanavians developed in relative isolation, which is why blond hair is so prevelant with them
Same for the celts
