    The relative investment of females and males into parental care might depend on the population’s adult sex-ratio. For example, all else being equal, males should be the more caring sex if the sex-ratio is male biased. Whether such outcomes are evolutionary ...

  • Olafsdottir, Steingerdur (University of Gothenburg, 2014-03)
    Several mechanisms have been proposed behind the associations between screens and overweight including sedentary behaviour, eating while viewing, and exposure to commercials. Aspects of this association as underlying social factors and the possible ...
