Therefore, the domestic horse today is classified as Equus ferus caballus. No genetic originals of native wild horses currently exist. The Przewalski diverged from the modern horse before domestication. It has 66 chromosomes, as opposed to 64 among modern domesticated horses, and their Mitochondrial DNA (mtDNA) forms a distinct cluster. [15]
The history of horse domestication has been subject to much debate, with various competing hypotheses over time about how domestication of the horse occurred. The main point of contention was whether the domestication of the horse occurred once in a single domestication event, or that the horse was domesticated independently multiple times.
Extinct equids restored to scale. Left to right: Mesohippus, Neohipparion, Eohippus, Equus scotti and Hypohippus. Wild horses have been known since prehistory from central Asia to Europe, with domestic horses and other equids being distributed more widely in the Old World, but no horses or equids of any type were found in the New World when European explorers reached the Americas.
But the timing of equine domestication and the subsequent broad use of horse power has been a matter of contention. An analysis of genome data from 475 ancient horses and 77 modern ones is ...
Around 4,200 years ago, one particular lineage of horse quickly became dominant across Eurasia, suggesting that’s when humans started to spread domesticated horses around the world, according to ...

The horse (Equus ferus caballus) is a domesticated, one-toed, hoofed mammal.It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus.The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today.
[153] [154] [155] However the horses domesticated at the Botai culture in Kazakhstan were Przewalski's horses and not the ancestors of modern horses. [ 156 ] [ 157 ] By 3000 BCE, the horse was completely domesticated and by 2000 BCE there was a sharp increase in the number of horse bones found in human settlements in northwestern Europe ...
