Humans suspected in horse extinction
Humans suspected in horse extinction Scientists at the University of Calgary believe
that humans may have been a factor in the extinction of ancient
horses. The discovery of a horse skeleton with smashed vertebrae
and butcher marks prove that humans were hunting the horses. They
"can't say people cause the extinction but we can say hunting was
effective in those extinctions." MAY 3, 2001
