How did they know they were indigenous bones? Was dead person's consent asked for to check if dead person wanted to be identified as ancestor of somebody?

I mean i understand caring for our dead, but anytime it's a matter of consent, its always for the living descendants, HIPPA protects medical records for 50 years, but they're generally protected so the living descendents don't feel impact for anything that maybe damaging.

And talking about laws I know it's a tangent, but the reason copyright exist after death is so that revenue can be enjoyed by living descendents. Laws are not necessarily sensible a lot of times.

oh hey i live in a neighborhood like that. my entire city is on an indian burial ground. every time they develop land, they survey, catalog, and gather the artifacts before placing them on land no one is supposed to know where but it's by the park.
