Edges (outgoing)

• relates → Iterated serial reproduction behaves as a Markov chain whose STATIONAR — cross-domain: iterated transmission of a representation across individuals

Incoming edges (what points here)

• In crows, mobbing is a self-reinforcing recruitment LOOP: 82% of scold — relates → this (recruiting a mob is the horizontal social-learning event itself)
