The reconstructed vocabulary is compatible with a Mesolithic hunter-gatherer culture and a north Eurasian landscape (spruce, Siberian pine, and various other species found in the Siberian taiga), and contains interesting hints on kinship structure. On the other hand, agricultural terms cannot be reconstructed for Proto-Uralic. Words for ‘sheep’, ‘wheat / barley’ and ‘flour’ are phonologically irregular within Uralic and all have limited distribution. In addition, the word for ‘metal’ or ‘copper’ is actually a Wanderwort (cf. North Saami "veaiki", Finnish "vaski" ‘copper, bronze’, Hungarian "vas", and Nganasan "basa" ‘iron’).
