eli5: How did primitive sheep contain/deal with all that wool when modern sheep require sheering yearly?

In: Biology

Answer 1

Earlier sheep would grow less wool, and they shed it like any animal with a summer and winter coat. Modern sheep have been selectively bred to not shed their wool, so the farmers can collect it all at once. Also, most modern sheep breeds are dumber and less agile than their ancestors.
