No, I just happened to remember reading about Slavey Lake. But it is my impression that some Native American groups did engage in slavery. As did many in Africa, even before they started dealing with Arabs and Europeans. So it's arguably not a stretch that early humans engaged in slavery. Indeed, I recall reading that the male breeding population was substantially smaller than the female breeding population for a while. I can't find the source, but it was maybe 10-50 kyr BP.
