Sheep are any of various ruminant animals related to the goats but stockier and lacking a beard in the male.
The sheep species Ovis aries has long been domesticated, and valued for its flesh and wool.
Wool is the soft wavy hypertrophied undercoat of various hairy mammals, especially sheep, made up of
a matrix of keratin fibers and covered with minute scales. Wool is also the product of wool, especially
a woven fabric or garment made of such fabric.
