In 2018, genomic comparison of 42 ancient-horse genomes, 20 of which were from Botai, with 46 published ancient and modern-horse genomes yielded surprising results. It was found that modern domestic horses are not closely related to the horses at Botai. Rather, Przewalski’s horses were identified as feral descendants of horses herded at Botai.
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.
Two major sources of information are used to determine where and when the horse was first domesticated and how the domesticated horse spread around the world. The first source is based on palaeological and archaeological discoveries; the second source is a comparison of DNA obtained from modern horses to that from bones and teeth of ancient ...
The genomic evidence showed that horses were first domesticated in Central Asia - northern Kazakhstan to be precise - about 5,500 years ago by people from what is called the Botai culture ...
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 ...
No animal has propelled humans into the modern world quite like horses. First domesticated in around 3500 BCE, horses have spread across the globe and, in the process, helped the spread of ...
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.
Modern horses were first brought to the Americas with the conquistadors, beginning with Columbus, who imported horses from Spain to the West Indies on his second voyage in 1493. [29] Horses came to the mainland with the arrival of Cortés in 1519. [30] By 1525, Cortés had imported enough horses to create a nucleus of horse-breeding in Mexico. [31]
