A study of cuttlefish, deer mice, horses, humans, laboratory mice, meadow voles, pine voles, prairie voles, rats, rhesus macaques, and talas tucu-tucus suggested that males’ superior spatial and navigational skills may be a side effect of testosterone and not an adaptive trait, as there would be no disadvantage if females were better navigators.
