Same DNA, Different Horse?
Selective breeding is rather common nowadays, getting characteristics that the breeder desires. It also results in harmful genetic mutations, often resulting in unhealthy animals, such as with dog breeding . There has also been discussion of bringing back extinct animals (which would be an exciting possibility when usable dinosaur DNA is found). One such case is a "prehistoric" horse, such as those seen in cave paintings. Mongolian Wild Horse (Przewalski’s horse) Credit: Wikimedia Commons / Ltshears / CC BY-SA 3.0 There is an extinct breed called the Tarpan, which had a resemblance to the critter pictured above as well as the cave paintings. People began breeding from wild mustangs that had some of the characteristics. Interesting that they did it without crossbreeding with the Przewalski's horse. This gives some insight not only into DNA, but also into the created biblical kinds. This is not evolution, since it involves variation and no added genetic material.
