Conventional archaeological understanding tended to date at around 2000–2500 BC. However radiocarbon gave dates as early as 3705 BC on wooden tools and 2874 BC on human remains. The earliest of these dates have now been rejected, giving a date of around 3300 BC for the start of the culture.
The culture is mainly known from its inhumations, with the deceased buried in conic or rectangular enclosures, often in a supine position, reminiscent of burials of the Yamna culture, believed to be Indo-European. Settlements have also been discovered. The Afanasevo people became the first food-producers in the area by breeding cattle, horses, and sheep. Metal objects and the presence of wheeled vehicles are documented. These resemblances to the Yamna culture make the Afanasevo culture is a strong candidate to represent the earliest cultural form of a people later called the Tocharians.
The culture became known from excavations in the Minusinsk area of the Krasnoyarsk Krai, southern Siberia, but the culture was also widespread in western Mongolia, northern Xinjiang, and eastern and central Kazakhstan, with connections or extensions in Tajikistan and the Aral area.
