Conformist transmission occurs across many social-learning species.

Evidence

Morgan et. al. (2012) and Muthukrishna et al. (forthcoming) provide the best current evidence of conformist transmission in humans, though also see Efferson et al. 2008, McElreath et al. 2005, 2008, Rendell et al. 2011, and Morgan and Laland 2012. On conformist transmission in fish, see Pike and Laland 2010. For an entry into the theoretical modeling literature, see Nakahashi, Wakano, and Henrich 2012 and Perreault, Moya, and Boyd 2012. This modeling work suggests we should find conformist transmission in many species reliant on social learning. — Joseph Henrich, The Secret of Our Success, 1122

Categorization

• QUESTION: This chapter is a Notes section — no developmental-timeline data on conformist bias emerges here. Confirms conformist transmission is documented in adults, and notes fish evidence, but the specific age-emergence question is not addressed.
