Another point that is worth mentioning - there was a post-Mongol invasion wave of resettlement into Central Ukraine from Galych and Volyn territories in the 14-16C. And another wave in the 18th C. after the Great Northern War. It might explain why ethnic Ukrainians in general are West shifted and so different from Russians genetically.
