Click on the links below to see videos of the three phases of learning from Mesoudi & O'Brien's virtual projectile point experiment.

One hunt from Phase 1 (oblique cultural transmission: a participant copies the arrowhead design of a player from a previous group)

One hunt from Phase 2 (individual learning/guided variation: a participant modifies the attributes of their arrowhead, with no access to anyone else's point design)

One hunt from Phase 3 (horizontal cultural transmission: a participant copies the point design of another member of their own group)
