Size doesn't matter for mammals with more complex brains, study finds.
Mammals that have evolved more developed brains tend to have smaller size difference between males and females of that species.
Scientists from the University of Bath in the UK looked at similarities between the genomes of 124 species of mammals.
They found that those species with a big difference in size between the sexes had bigger gene families linked to olfactory functions.
