Markets misinterpreted? A comment on Sánchez-Amaro and Amici (2015)

•We discuss Sánchez-Amaro and Amici (2015)'s review on biological market theory (BMT).•BMT is a functional theory, and thus does not postulate a particular mechanism.•BMT and Seyfarth's model are distinct models with different testable predictions.•We correct some of the cited literature, including our own work, that is misquoted.•We argue that there is more evidence in support of BMT than the authors acknowledge.
