Texas FFA Livestock Judging Practice Test

The correct answer is Aurochs because modern domestic cattle (Bos taurus) are descendants of this wild ancestor. Aurochs were large, powerful wild cattle that once roamed across Europe, Asia, and North Africa. They were domesticated by early humans around 10,000 years ago and selectively bred for desirable traits, leading to the various breeds of cattle we have today. Understanding this lineage is essential in livestock judging, where recognizing the genetic background and evolutionary history of animals plays a significant role in assessing their qualities and potential for breeding.

Other options refer to specific breeds or species that do not directly represent the single early ancestor of modern cattle. Himalayan Yaks are a distinct species adapted to high altitudes, while Chianina and Jersey are specific breeds of domestic cattle developed for particular agricultural purposes, rather than being the common ancestor from which all modern cattle evolved.
