In the north, a similar scenario to Indo-European is thought to have occurred with Uralic languages expanding in from the east. In particular, while the Sami languages of the indigenous Sami people belong in the Uralic family, they show considerable substrate influence, thought to represent one or more extinct original languages. The Sami are estimated to have adopted a Uralic language less than 2,500 years ago. Some traces of indigenous languages of the Baltic area have been suspected in the Finnic languages as well, but these are much more modest. There are early loanwords from unidentified non-IE languages in other Uralic languages of Europe as well.
