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

Ceffylau (Latin Equus) yw'r unig deulu modern o garfan geffylau'r rhai nad ydynt yn gryman.

Systematig
Mae systemateg ceffylau yn ddadleuol. Yn ôl y dull tacsonomeg mwyaf cyffredin, mae genws ceffylau yn cynnwys saith rhywogaeth:

  • Ceffyl gwyllt
  • Ceffyl cartref
  • Przhevalsky Ceffylau
  • Kiang
  • Kulan
  • Ass gwyllt
  • Ass domestig
  • Mynydd Sebra
  • Sebra Anialwch
  • 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.

Mae esblygiad y ceffylau wedi'i ddogfennu'n dda gan y ffosilau, sy'n tystio i'r ffaith, am 50 miliwn o flynyddoedd, anifail bach, maint-an-coed, â'i fysedd yn hytrach na charnau, wedi dod yn fawr preswylydd anniben mannau agored. Digwyddodd y prif ffurfiant ar rywogaethau o fewn terfynau Gogledd America, lle o'r bont naturiol bresennol y digwyddodd eu treiddiad i Ewrasia pan oedd hyn yn bosibl yn absenoldeb Afon Bering a chyn ffurfio tarian rewlifol pwerus.

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.
