Horse 3D models may vary a lot, sometimes it’s interesting to know more about the object of 3D modeling.

Zirgi (latīņu Equus) ir vienīgā moderna ģimenes, kas nav sirpjveida.

Sistemātika
Zirgu sistemātika ir pretrunīga. Saskaņā ar visizplatītāko taksonomijas metodi zirgu ģints sastāv no septiņām sugām:

  • Savvaļas zirgs
  • Mājas zirgs
  • Zirgs Przhevalskis
  • Kiang
  • Kulan
  • Savvaļas ass
  • Iekšzemes ass
  • Kalnu Zebra
  • Desert Zebra
  • Burchell’s zebra

There are some divergent views on this classification. Osla and Kulana are sometimes isolated in the separate genus Asinus, arguing that these two species were separated from the rest in the Pliocene. The Przewalski horse and the domestic horse are usually considered to be two different species due to the different amount of chromosomes. Sometimes the first ones are still included in the domestic horse. According to Paleogenetics, Przheval’skii horses are feral descendants of the Botanian horses.

Kulans are divided into a number of subspecies, which some zoologists regard as independent species. Depending on the point of view, there are up to seven types of kulans. Some zoologists prefer to divide the plain zebras on the Bruxelles zebras and quagg. The three above-mentioned species of zebras are sometimes united into a common zebral subgenus, which, however, is conditional, since the relationship between these three species is not more closely related than with other species.

Zirgu evolūcija ir labi dokumentēta ar fosilijām, kas liecina par to, ka 50 miljonu gadu laikā mazs, suņu izmērs, meža dzīvnieku pro-paleota, ar pirkstiem, nevis pirkstiem, ir kļuvis par lielu nemierīgs brīvo telpu iedzīvotājs. Galvenā sugu veidošanās notika Ziemeļamerikas robežās, kur no esošā dabiskā tilta viņu iekļūšana Eurāzijā notika, kad tas bija iespējams bez Beringa šauruma un pirms spēcīga ledus vairoga veidošanās.

The evolution of horses began in the Eocene, about 55 million years ago. At that time, there existed a gyroecortium, the ancestor of all the present horses, a small animal with a height of only 20 cm in shoulders, and the leaves and fruits that had plucked their small teeth. Giracotria did not resemble today’s horses at all. This animal had a curved back, a short neck and a muzzle, short paws and a long tail. It was a stocky fox-sized creature with four-legged limbs. The skull and volume of the brain were relatively small.
