Fish study links brain size to parental duties

19 agosto 2014

Male stickleback fish that protect their young have bigger brains than counterparts that don’t care for offspring, finds a new study. «This suggests that regular sticklebacks have bigger brains to handle the brain power needed to care for and protect their young,» says the study’s lead author. «This is one of the first studies to link parental care with brain size.»
