Abstract
How does ecology influence cognitive evolution in lizards? Taking a comparative approach, De Meester et al. (2022) discovered that species living in temporally fluctuating environments tend to perform relatively poorly on cognitive tasks associated with behavioral flexibility compared to species living in more climatically stable environments. The negative association between environmental variability and cognitive performance suggests that stochastic environments can hamper, rather than stimulate, the evolution of cognitive ability.
