It is, of course, the case that all animals are continuously evolving, even if some of them don't change much visibly over protracted periods of time. So we can't really point to a modern species and say that this is the kind of thing that everything else in its group evolved from. But some have, at least on visible examination, changed far less from their ancestors than others. They have found some suitable niche in which to live, and, because they're environment hasn't changed much, they've been able to stay more or less the same. It's not that they haven't changed, of course, but just that the changes are relatively subtle.
In the case of the goats, the species that have probably changed the least from the ancestral form are the
serows and gorals of eastern Asia. Both kinds of animal have retained a "resource defender" lifestyle, where they find patches of lush food in the otherwise rocky wastes of precipitous cliffs and mountainsides, and defend them from all comers.
