Studies examining other regions of DNA have revealed a high genetic diversity in horses, which is consistent with mtDNA results; however, pinpointing where domestication events have taken place remains elusive. For example, research at the turn of the 21st century indicated that there appeared to have been an independent domestication event in the Iberian Peninsula (the region containing Spain and Portugal), which served as a refuge for many species, including horses, during the Pleistocene and Holocene glaciations. Some two decades later, genetic studies cast doubt on whether such an event took place in Iberia, since those horse lineages became extinct before leaving significant genetic traces in the genomes of modern horses. In addition, genetic studies of other proposed centres of horse domestication, such as Anatolia and the Caucasus (which have long histories of horse utilization), have not turned up proof of single independent domestication events.Most evidence indicates that humans spread domestic horses from western Eurasia and that domestic populations were supplemented with wild individuals which increased the genetic diversity of domestic horses. Based on modern genetic analyses, the answers to the questions surrounding horse domestication are that the horse has a diverse ancestry, that there was more than one domestication event, and that domestic horses have been widely interbred throughout the history of their domestication.

We’re so used to seeing horses, we often forget just what a bunch of weirdos they are. Let’s start with their feet: can you name another animal with only one hoof? If you said cow, sheep or goat, then you need to take a closer look next time you’re on the farm, because they all have two hooves per foot. Deer – likewise. The next curiousquestion: how did such a powerful animal come to have an upstart ape lead it around by the mouth, and sit on it?The evolutionary history of horses is relatively well understood, but there are still some gaps in our knowledge, and new discoveries continue to be made. So where do these strange animals come from, and how did we end up with the domesticated breeds so familiar to us todayTalking about toe-numbers is not arbitrary. Horses belong to a group called perissodactyls, or odd-toed ungulates. This group includes horses, tapirs, rhinos and a wealth of extinct animals such as the clawed, long-forelimbed chalicotheres and the rhino-like brontotheres. They contrast with even-toed ungulates, or cetartiodactyls. This group include hippos, deer, giraffes, alpacas and most common farm animals such as pigs, sheep and cows. Also included are the cetaceans: the whales and dolphins. Although they may have shed their toes on their journey to a streamlined aquatic life, we know from genetics and the shape of their skeletons that they share an ancestor with the rest of the even-toed ungulates. Cetartiodactyls are by far the most populous of the two ungulate groups today, but it wasn’t always so.
