why is it that many people in Central Asia and Iran,Afghanistan,Pakistan have white features?

Answer 1

I am no expert but it may be something to do with the migration patterns of the earliest humans. Moderm man originated in the Rift Valley of east Africa and spread from there to North Africa, what is now the middle east, the Indus Valley, India and then to the far east, across the Baring Strait and into modern Canada, the USA and down into Central and South America.

From the migrations to the Middle East a sub-branch made its way to Europe, as these people were identical in genetic make up and faced somewhat similar climatic and environmental conditions their facial features became similar.

But again I may be completely wrong.

Answer 2

In Indian history there is a theory that the whole culture is based on the immigration into India of a race from the west known as the Arian's. MOF: History is broken up into the pre-Arian and post-Arian eras.

Another possible explanation is that you are talking about areas that are located on the famous Silk Route. Traders traveled back and forth from Asia Minor to China. Some might have settled somewhere along the way...
And you know what they say about "traveling salesmen!"

A third possible explanation is that since Europe and the countries you mention are on about the same latitude, have about the same climate and have about the same vegetation, the natives who live in these regions (including Europe) would develop the same type of physical features.
