A cool find, but not necessarily surprising: all modern populations have some art in their culture, but modern populations diverged >70 kya. One might imagine that our common ancestors had similar behaviors to all living humans, at least those behaviors which have not been transmitted culturally in recent years (especially when you take long-isolated or unique peoples into account; e.g. Amazonian and Papuan tribes, San hunter-gatherers, etc.).
