A novel study has unveiled that Asians and Europeans dating 5,000 years ago were light-skinned and lactose intolerant.

The Bronze Age in Europe and Asia is considered to be a dynamic period that involved large-scale human migration throughout region.

Study’s lead researcher Morten Allentoft of the University of Copenhagen’s Natural History Museum was of the view that activities carried out in Bronze Age are considered to be responsible for changes in pre-day demographics in Europe as well as Asia.

The study researchers have sequenced genomes from 101 humans from across European and Asian regions. After studying the data, the researchers affirmed, “That light skin pigmentation in Europeans was already present at high frequency in the Bronze Age. Our results indicate the presence of blue eyes already in Mesolithic hunter-gatherers”.

The researchers affirmed that it has been evident that human inhabitants in the European and Asian regions have adapted to their environments. As per the researchers, the most important discovery was that they were lactose intolerant, which suggests that milk consumption did not happen before 5,000 years ago.

The migration has influenced central European cultures and languages. The migration led to horses and wheel introduction that changed lifestyles of many people. The new study has used a new approach to study ancient humans.

Rather than digging bones or artifacts, the researchers have carried out genome assessment. The researchers have started to sequence ancient DNA of people who wandered Europe centuries ago.

Already, the researchers have been uncovering important details about humans that lived between 3,000 B.C.E and 1,000 B.C.E.
