The transformation of wild animals into domestic ones available for
human nutrition was a key prerequisite for modern human societies.
However, no other domestic species has had such a substantial impact
on the warfare, transportation, and communication capabilities of
human societies as the horse. Here, we show that the analysis of
ancient DNA targeting nuclear genes responsible for coat coloration
allows us to shed light on the timing and place of horse
domestication. We conclude that it is unlikely that horse
domestication substantially predates the occurrence of coat color
variation, which was found to begin around the third millennium before
the common era.

Mystery Of Horse Domestication Solved?

ScienceDaily (Apr. 24, 2009) — Wild horses were domesticated in the
Ponto-Caspian steppe region (today Russia, Kazakhstan, Ukraine,
Romania) in the 3rd millennium B.C. Despite the pivotal role horses
have played in the history of human societies, the process of their
domestication is not well understood.

In a new study published in the scientific journal Science, an
analysis by German researchers from the Leibniz Institute for Zoo and
Wildlife Research, Berlin, the German Archaeological Institute, the
Humboldt University Berlin, the Max Planck Institute of Evolutionary
Anthropology, Leipzig, in cooperation with American and Spanish
scientists, has unravelled the mystery about the domestication of the
horse.

Based on ancient DNA spanning the time between the Late Pleistocene
and the Middle Ages, targeting nuclear genes responsible for coat
colorations allows to shed light on the timing and place of horse
domestication. Furthermore the study demonstrates how rapid the number
of colorations increased as one result of the domestication. As well,
it shows very clearly that the huge variability of coloration in
domestic horses which can be observed today is a result of selective
breeding by ancient farmers.

Our modern human societies were founded on the Neolithic revolution,
which was the transformation of wild plants and animals into domestic
ones available for human nutrition. Within all domestic animals, no
other species has had such a significant impact on the warfare,
transportation and communication capabilities of human societies as
the horse.

For many millennia, horses were linked to human history changing
societies on a continent-wide scale, be it with Alexander the Great’s
or Genghis Khan’s armies invading most of Asia and Eastern Europe or
Francis Pizarro destroying the Inca Empire with about 30 mounted
warriors. The horse was a costly and prestigious animal in all times,
featured in gifts from one sovereign to another as a nobleman’s mark.
