You’re not wrong but there isn’t a domesticated animal or plant that we haven’t selectively breed so the traits we want to see more of aren’t expressed more prominately.

While we shouldnt be cruel to animals, just want to point out that Lamarckian evolution was proven false by Darwin already.

Sheep didn’t evolve to require it by the constant shaving, farmers would have likely selected for highly producing animals if anything.

It depends on the variety. Some sheep do need to be sheared, but others shed naturally and their wool can simply be combed out.
