Relatively little is known about the inhabitants of pre-Indo-European "Old Europe". The Basque language remains from that era, as do the indigenous languages of the Caucasus. The Sami are genetically distinct among the peoples of Europe, but the Sami languages, as part of the Uralic languages, spread into Europe about the same time as the Indo-European languages. However, since that period speakers of other Uralic languages such as the Finns and the Estonians have had more contact with other Europeans, thus today sharing more genes with them than the Sami.
