Bayesian animals sense ecological constraints to predict fitness and organize individually flexible reproductive decisions

  • Patricia Adair Gowaty (a1) and Stephen P. Hubbell (a1)

Abstract

A quantitative theory of reproductive decisions (Gowaty & Hubbell 2009) says that individuals use updated priors from constantly changing demographic circumstances to predict their futures to adjust actions flexibly and adaptively. Our ecological/evolutionary models of ultimate causes seem consistent with Clark's ideas and thus suggest an opportunity for a unified proximate and ultimate theory of Bayesian animal brains, senses, and actions.
