Based on the reconstructed Proto-Indo-European language, some things about their culture can be determined with confidence:
* they used a kinship system based on relationships between men[1]
* they worshiped a sky god,[2] *dyeus ph2tēr (lit. "sky father"; > Gr. Ζευς (πατηρ) / Zeus (patēr); *dieu-ph2tēr > Lat. Jupiter)[3]
* they knew transportation by or across water[1]
* they practiced agriculture and cultivated cereals, and attested a technology commonly ascribed to early farming communities[2]
* they composed and recited heroic poetry or song lyrics that used stock phrases like imperishable fame[1]
* the climate they lived in had snow[4]
* Stockbreeding and animal husbandry were important to their economy, and their animals included domesticated cattle and horses[1].
They had domesticated the horse - *eḱwos (cf. Latin equus). The cow - *gwous - played a central role, in religion and mythology as well as in daily life. A man's wealth would have been measured by the number of his animals (small livestock) - *peḱus (cf. English fee, Latin pecunia).
* they had knowledge of the domestic dog[1]
* they knew the wheel,[1] and had carts with solid wheels, but not yet chariots with spoked wheels
