If lizard mums are anything like mine, when they are cold they will order their son to put on a jumper. Well, turns out, lizards’ mums ARE like mine. Being the mean researcher that I am, I decided to scare a bit lizard mums during gestation, by putting them in presence of snake olfactive cues (yeah, in addition to being scary, snakes also stink). I maintained them like that for one month, and then after the females laid eggs, I investigated offspring phenotype.
