Our paleogenetic study of pre- and protohistoric horses in Anatolia and the Caucasus, based on a diachronic sample from the early Neolithic to the Iron Age (~8000 to ~1000 BCE) that encompasses the presumed transition from wild to domestic horses (4000 to 3000 BCE), shows the rapid and large-scale introduction of domestic horses at the end of the third millennium BCE. Thus, our results argue strongly against autochthonous independent domestication of horses in Anatolia.
...
Because northern Eurasia, and in particular the Pontic-Caspian steppe, is currently the most likely origin for the domestic horses brought into Anatolia, there are two possible introductory routes, one via southeastern Europe and one via the Caucasus.
...
our identification of several allochthonous mitochondrial lineages and coat color mutations appearing broadly contemporaneously in the southern Caucasus and in central Anatolia argues in favor of a dispersal route via the Caucasus.
...
Although the cultural processes initiating the dispersal of horse husbandry south of the Caucasus are currently difficult to address, it may relate to human population movements into the Caucasus and subsequently into Anatolia beginning in the late third millennium BCE.

Guess who?

De-Turanization should include phasing out equestrian sports.

Horse racing is a popular equestrian sport which is practiced in many nations around the world. It is inextricably associated with gambling, where in certain events, stakes can become very high. Despite its illegality in most competitions, these conditions of extreme competitiveness can lead to the use of performing-enhancing drugs and extreme training techniques, which can result in negative side effects for the horses' well-being. The races themselves have also proved dangerous to the horses – especially steeplechasing, which requires the horse to jump hurdles whilst galloping at full speed. This can result in injury or death to the horse, as well as the jockey.[48] A study by animal welfare group Animal Aid revealed that approximately 375 racehorses die yearly, with 30% of these either during or as a result of injuries from a race.[49] The report also highlighted the increasing frequency of race-related illnesses, including bleeding lungs (exercise-induced pulmonary hemorrhage) and gastric ulcers.[49]

Animal rights groups are also primarily concerned that certain sports or training exercises may cause unnecessary pain or injuries to horse athletes. Some specific training or showing practices are so widely condemned that they have been made illegal at the national level and violations can incur criminal penalties. The most well-known is soring, a practice of applying a caustic ointment just above the hooves of a Tennessee Walking Horse to make it pick up its feet higher. However, in spite of a federal law in the United States prohibiting this practice and routine inspections of horse shows by inspectors from the United States Department of Agriculture, soring is still widespread and difficult to eliminate.[50] Some events themselves are also considered so abusive that they are banned in many countries. Among these are horse-tripping, a sport where riders chase and rope a loose-running horse by its front legs, throwing it to the ground.[51]
