Domestication of the horseとは 意味・読み方・使い方

There are a number of hypotheses on many of the key issues regarding the domestication of the horse. Although horses appeared in Paleolithic cave art as early as 30,000 BCE, these were truly wild horses and were probably hunted for meat. How and when horses became domesticated is disputed. The clearest evidence of early use of the horse as a means of transport is from chariot burials dated c. 2000 BCE. However, an increasing amount of evidence supports the hypothesis that horses were domesticated in the Eurasian Steppes (Dereivka centered in Ukraine) approximately 4000-3500 BCE. Recent discoveries on Botai culture suggest that Botai culture settlements in the Aqmola Province of Kazakhstan are the location of the earliest domestication of the horse.
