According to the latest research, Sir Mixalot's passion and penchant for large posteriors would also have been of benefit to his progeny.
Professors William Lassek and Steven Gaulin from the University of Pittsburgh have been professionally studying bums (and not in the way that those guys who were arrested in the bushes outside our office were either) and believe that they've figured out the reason that women are naturally curvier than men.
It seems that, according to their research, a baby's brain development is aided by the fat stored in the hips and buttocks of their mother, as a result of the fact that these areas are used during breastfeeding. Speaking to The Sunday Times, Lassek said "You need lots of fat to make a nervous system and the fats in these areas are also enriched in DHA [docosahexaenoic acid] which is a particularly important component in the human brain."
He added that in most mammals, body fat is quite low and ranges between 5-10%, but in women that is typically closer to 30%, as the body has adapted and evolved to hold on to the fat in those areas to aid in the development of their child. He added that this has also meant that men have evolved to be attracted to women with curvier hips, as they "are likely to give birth to healthier and more intelligent babies", although he does admit that there are other factors that come in to it apart from that.
