Mammals, including man, have a much better chance to seduce the opposite sex if their teeth look healthy and beautiful. These are not modern aesthetic ideas, a mechanism developed by evolution hundreds of millions of years ago, says an international team of paleontologists.

the Interest of scientists was the fact that in ancient times some herbivores (for example, lived during the Triassic period decendancy) had sharp fangs. If the need for pointed teeth obvious to predators, herbivores are much more profitable to have flat teeth well suited for chewing plant food. Experts have rejected the theory that herbivorous fangs were needed for protection from predators, and suggested that they were needed in order to attract individuals of the opposite sex.

Scientists from the University of Witwatersrand in South Africa and the European research facility ESRF in France, came to the conclusion that the teeth as an element of sexual attraction more than 250 million years ago began to “use” ancient pangolins, presumably consisting of modern mammals in close relationship — Choerosaurus dejageri. The shape of the jaw and teeth of these animals has allowed professionals to assume that their fangs they showed in the first place, while “significant,” battles with competitors for mates — for use in a real battle they would be too weak.

Sexual selection is a special case of natural selection and its role in evolution for a long time largely underestimated. We are talking about that certain external features of males, or (much rarer) females attract animals of the opposite sex and are perceived by them as a sign of health. Because these traits increase the chance individuals to leave offspring, with each generation they are more and more explicitly fixed in the population.

experts suggest that they published in the journal PloS ONE, the work suggests that the role of sexual selection in the evolution was even more significant, SEM is considered to be today.
