Changes

==Summary==

Invasions have shifted human history in many ways. The genetic shifts represent a physical manifestation of how populations shifted or changed as new migrants arrived or were displaced and moved around. The shifts that occurred in the Mongol period are a clear indication of large-scale expansion of a limited number of groups, namely Mongols and Turks, across much of Eurasia. The expansion of Turkish and Turkish successor states are one evident result of this; however, the cultural changes were more minimal, as the new populations often adopted the cultures and religions of the groups they integrated with. Population makeup did shift, as new genetics were introduced into the older population genetic makeup.
