The occupations of the Botai people were connected to their horses. Some researchers state that horses were domesticated locally by the Botai. It was once thought that most of the horses in evidence were probably the wild species, Equus ferus, hunted with bows, arrows, and spears. However, evidence reported in 2009 for pottery containing mare's milk and of horse bones with telltale signs of being bred after domestication have demonstrated a much stronger case for the Botai culture as a major user of domestic horses by about 3,500 BC, close to 1,000 years earlier than the previous scientific consensus. Botai horses were primarily ancestors of Przewalski's horses, and contributed 2.7% ancestry to modern domestic horses. Thus, modern horses may have been domesticated in other centers of origin. The pottery of the culture had simple shapes, most examples being gray in color and unglazed. The decorations are geometric, including hatched triangles and rhombi as well as step motifs. Punctates and circles were also used as decorative motifs. Current research is being conducted by Alan Outram of Exeter University in association with other institutes, the Bristol, Winchester, and Kokshetau universities, and the Carnegie Museum. Along with students, Outram conducted a magnetometer survey of the Botai site in 2008, and is looking into conducting further research into the Botai culture's role into the development of horse domestication.
Language reconstruction
believes that the language of the Botai culture cannot be conclusively identified with any known language or language family. He speculatively suggests that the Proto-Ugricword*lox for "horse" is a borrowing from the language of the Botai culture.
Archaeogenetics
A 2018 paleogenetic study took samples from three different Botai individuals for DNA extraction and analysis. Two of them turned out to be genetically male, and another one is genetically female. Two of the samples were taken from crania curated in Petropavlovsk Museum, denoted as "Botai Excavation 14, 1983" and "Botai excavation 15". Autosomally, Botai population turned out to be closer to the Ancient North Eurasian component than the Yamnaya population. No significant gene flow between Botai and Yamnaya was observed. Botai 14 has a calibrated radiocarbon date range from 3108–3517 cal BC, and Botai 15 from 3026–3343 cal BC. Regarding Y-DNA, Botai 14 was determined to carry a derived allele at R1b1a1-M478, and Botai 15 belonged to the basal haplogroup N*-M231. Regarding mitochondrial DNA, the Copper Age Botai sample BOT2016 belonged to the haplogroup Z1a, Botai 15 - to R1b1, and Botai 14 - to K1b2.
