Analysis of differences between these genomes indicated that the last common ancestor of modern horses, donkeys, and zebras existed 4 to 4.5 million years ago. [40] The results also indicated that Przewalski's horse diverged from other modern types of horse about 43,000 years ago, and had never in its evolutionary history been domesticated. [27]
Equidae (commonly known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, asses, and zebras, and many other species known only from fossils. The family evolved more than 50 million years ago, in the Eocene epoch, from a small, multi-toed ungulate into larger, single-toed animals.
The horse (Equus ferus caballus) [2] [3] 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
Around 4,200 years ago, one particular lineage of horse quickly became dominant across Eurasia, ... then sauntered across the Bering Strait into Asia around a million years ago. They flourished in ...
Think in New York or Washington 200 years ago, with carriages pulled by horses in the streets," Librado said. The genomic evidence showed that horses were first domesticated in Central Asia ...
End Ordovician: 440 million years ago, 86% of all species lost, including graptolites; Late Devonian: 375 million years ago, 75% of species lost, including most trilobites; End Permian, The Great Dying: 251 million years ago, 96% of species lost, including tabulate corals, and most trees and synapsids
Merychippus is an extinct proto-horse of the family Equidae that was endemic to North America during the Miocene, 15.97–5.33 million years ago. [2] It had three toes on each foot and is the first horse known to have grazed .
The split between Przewalskii's horse and E. caballus is estimated to have occurred 120,000–240,000 years ago, long before domestication. Of the caballine equines of E. ferus, E. f. ferus, also known as the European wild horse or "tarpan", shares ancestry with the modern domestic horse. [ 58 ]
