"This is without a doubt the best early example of a
domesticated horse sculpture," Zarins maintains.
When researchers tested their DNA and compared it to the bones of ancient horses, they found the Przewalskis were not wild as previously believed, but feral, meaning they descended from
domesticated horses that later returned to the wild.
Genetic research, published in Science, shows that the Przewalski horse, considered to be the last wild species on Earth, is in fact a descendant of the earliest
domesticated horses.
Colic causes pain in a horse's stomach and is the leading cause of premature death in
domesticated horses.
By 2000 BCE horses were pulling chariots in Eurasia, and by 1500 BCE
domesticated horses were well ensconced in the Levant and Egypt.
Nevertheless, this standpoint was not supported by mtDNA evidence (Ishida et al., 1995; Oakenfull and Ryder, 1998; Oakenfull et al., 2000; Goto et al., 2011) and Y chromosome evidence because two fixed Y chromosome variations were detected in
domesticated horses and Prezewalski's horses (Wallner et al., 2003).
