Science is so oriented that there is more research on Europeans than any other human group.
The first modern peoples of Europe may have had dark skin and blue eyes. Cheddar man from about 10,000 years found in Somerset. Cheddar Man's remains had been unearthed 115 years ago in Gough's Cave, located in Somerset's Cheddar Gorge. DNA analysis allows them to predict skin and eye pigmentation. Pictures are artistic representations.
It is believed immigrants came from perhaps the middle east that brought in farming and lighter skin and then later Indo-Europeans speakers brought in a genetic mutation that allows people to drink milk and as adults to digest the milk sugar lactose. There are claims also that brain size got smaller too.
Scientists have done a lot of work on this lactose gene mutation.
What they are finding is the European mutated gene say 10,000 yr ago was not present, but 'Lactase persistence is a common genetic trait in Europeans and other pastoralists. New ancient DNA evidence from a Bronze Age battlefield indicates that selection for lactase persistence was strong and on-going in the last 3,000 years.'
In Europe this gene is most common in the Nordic areas of Europe.
While 65% or more of the total human population are lactose intolerant, in some human populations lactase activity commonly persists into adulthood. Lactose tolerance is exceptionally widespread in Northern European countries such as Sweden and Finland, with tolerance levels of 74% and 82%, respectively.
Below is a map that shows that lactose intolerance decrease in the nordic area of europe. In england it is very low. What is now the UK and also Ireland were hit by two huge waves of Indo-European speaking peoples. first the celts and then various Germanic tribes such and Saxons and then Vikings that all may have carried the mutated gene. Allowing milk to be consumed by adults gives a very strong selection for people with this gene and so they survive to procreate this gene.
