"More than wool"

• Sheep are often underestimated as passive animals, but they are actually an excellent example of early human-driven evolution. They were domesticated 11,000 years ago in the Fertile Crescent (pictured above) and were the first animals to be selectively bred by humans which lead to changes in behavior and appearance. Beyond agriculture, sheep are also known for their strong spatial memory and are able to recognize over 50 individual faces. Studies also suggest that they are capable of experiencing empathy and emotions.The evolution of sheep reflects a long-standing and co-dependent relationship with humans.
