ELI5: How have sheep existed in the wild without someone to shear them?

I saw a post about a sheep that escaped owners/shearing for years and its wool was out of control. Have sheep ever existed in the wild without someone to shear them?

They don’t.

Domesticated sheep have been bred to never shed their seasonal coat and continue growing wool all year.

In the wild they’d shed this regularly to avoid overheating in the summer months.

Domesticated sheep that do escape will eventually overgrown and die.
