They can only study links to populations in the past, when they dig up the bodies of the past, take their DNA and see if they Share the same traits.

They can not study the HISTORY of any population, UNLESS they dig up bodies from the PAST and examine them !

They can NOT compare the physical data of present humans with past humans, If they don't dig up the bodies of the past, then have NOTHING to test or compare !

You can not compare any thing unless you have both things to compare. Do they claim to have the bodies of any 3,500 people to compare modern men with?
