The Genetic Map of Europe The extent of genetic variation is greater north to south than east to west. This may be a result of the way Europe was colonized by modern humans, i.e. from the south, in three successive waves of migration (45,000 years ago, where before there had only been Neanderthals; 17,000 years ago, after the last Ice Age; and 10,000 years ago, with the advent of farming techniques from the Middle East).
