The founder of Brazil 's Miss BumBum competition has called on women to stop trying to copy Kim Kardashian , claiming the trend towards ever bigger bottoms is 'a cause for national concern'. Cacau Oliver, owner of the hugely successful best butt competition franchise, claims Brazilian women have become 'so obsessed' by the American reality star that most 'style their own bum on hers'. And he appealed for them to be more 'patriotic' and avert a crisis by preserving the natural beauty of the iconic Brazilian bottom famous around the world. Cacau Oliver, the found of the Miss BumBum contest has said Brazil is facing a 'national crisis' over the size of women's bottoms, with constant pressure to make them bigger. Mr Oliver urged Brazilian women to be 'patriotic' and keep their natural curves, rather than using surgery to enhance their features. The annual 'best bottom' contest is now in its eighth year and is Brazil's most popular beauty pageant, with women who are crowned Miss Bumbum becoming overnight celebrities. But last year the competition changed its rules to ban contestants whose backsides exceeded 43 inches in diameter - the same as Kim Kardashian's famous asset.

Butts are definitely having a moment , and now science might actually have an answer to why we're all about that bass. Researchers at Bilkent University in Turkey showed men silhouettes of women's bodies and asked to rank them in order of preference. They found that the men were most attracted to women whose spines curved exactly 45 degrees above the top of their butts, but that the men were actually more attracted to the spinal curve — known as vertebral wedging — than the butts themselves. The researchers say that having "extra mass around the buttocks" enhanced the appearance of the curvature. David Lewis, one of the researchers on the study, told Daily Mail that vertebral wedging developed out of necessity. Subsequently, women who developed this vertebral wedging were able to "forage longer" for food during pregnancy and carry multiple pregnancies with a lower risk of injury, which Dr. Lewis says would have been "sexually attractive" to men because of the evolutionary advantage it provided. However, the researchers noted that the study isn't conclusive and that more research is needed to really understand the preferences for either a big butt or a pronounced spinal curve. I think this is the more important takeaway: The next time a guy tells you he's an ass man, you can go ahead and tell him he's actually a spine man.

You already know that some men love a big butt, but it looks like science is breaking down the infatuation might have more to do with the curve of a woman's spine. A study at Bilkent University showed women different silhouettes of women with different degrees of curvature in their spines. They then rated which they found most attractive. In the end, majority of men were attracted to a woman who has a spine with a curve of You may think this is a weird thing for men to notice - and it is, more on that later - but the attraction is actually tied into a woman's fertility: women with curvier spines are more fertile. So does the attraction of the curve of her backside have anything to do with the size of her butt?
