Female mosquito fish grow bigger brains to help avoid the rough attentions of over-endowed males (17/24/31 December 2016, p 12). A few pages later you report brainy female wild red deer living longer and producing more offspring (p 15). Could there be a connection here? Time for the cervidologists to get out their measuring tapes, but not during the rut, I think.
