Horse domestication revolutionized transportation, accelerated communication, and transformed warfare in prehistory. Yet the identification of early domestication processes has been problematic.
In a paper published in the journal Science on March 6, 2009 archaeologist Alan K. Outram and seven co-authors published "three independent lines of evidence demonstrating domestication in the Eneolithic Botai Culture of Kazakhstan, dating to about 3500 B.C.E. Metrical analysis of horse metacarpals shows that Botai horses resemble Bronze Age domestic horses rather than Paleolithic wild horses from the same region. Pathological characteristics indicate that some Botai horses were bridled, perhaps ridden. Organic residue analysis, using δ13C and δD values of fatty acids, reveals processing of mare's milk and carcass products in ceramics, indicating a developed domestic economy encompassing secondary products" (http://www.sciencemag.org/cgi/content/abstract/323/5919/1332, accessed 03-06-2009).
Prior to discovery of this evidence horse domestication was thought to have occurred around 2500 BCE.
♦ Before horses were domesticated it appears that prehistoric people mainly killed horses for food. One of the most celebrated collections of horse and reindeer bones was found beneath the precipice at the paleolithic site of Solutré in France. Though prehistoric people primarily hunted the reindeer for food and other necessities of life, an explanation for the immense deposit of bones at Solutré is that prehistoric people stampeded reindeer and horses over the cliff as a means of killing them.
