Hair of Domestic Sheep
Unlike their wild cousins the domestic sheep doesn’t have long and fluffy wool on their body instead they have short hairs, these hairs are tightly packed and varies color from white, brown and black. Some breeds are capable of producing wool but, they do not produce wool at the same volume as other fiber sheep, but their hair more valuable The formation of the hairs comes as a result of the domestication. Sheep were domesticated by humans around 10,000 BC. They were among the first animals domesticated. As sheep were raised under tamed conditions, they went through several changes. They began to develop more wool than hair and vise versa..
