This is well-documented in Humankind: A Hopeful History by Rutger Bregman. It's worth a read, as it also dispels other experiments in human behaviour that have subsequently been difficult to replicate (for a variety of reasons).

Yep, great book. Also dispels the Lord of the Lies myth that people have taken as gospel.
