Wow some of you Guys complain about using "components" from Calculators as evidence but at the same time use pseudo science s.... talk like "The Corded and Kurgan mummies look different from West Asians" because they are Indo-Europinized Hunthers and Gatheres. The Indo European people living in West, Central and South Asia look also different from your Corded Indo Europeans. So what?
And all of you seem to forget or most probably ignore that there is a mutation in R1a which divides the two most common lineages. Almost all of the R1a in Central and South Asia is different from that in the Steppes!
Dont ignore facts and start to use pseudo science thinks like "pigmentation and headshape can change with different forms of diets, living standards and environment.
Look at these Kalash.
They look like your typical "Corded Ware" mummies dont say? Yet they are genetically much more distant to Europeans than most other West Eurasian populations.
