After dogs, goats (and sheep) were among the earliest animals to be domesticated. Evidence from archaeological sites in Iran indicates that sheep and goats were domesticated about 9,000-10,000 years ago. As animals became domesticated, their physical appearances changed. These images show the physical differences between a wild goat (left) and a domesticated goat (right). As just one example, in wild goats the horns sweep backwards like a curved sword, while in domesticated goats the horns are a twisted, corkscrew shape.
