Scientists have found a link between heart disease and reproduction

Ученые нашли связь между болезнями сердца и размножением

Some changes that increase the attractiveness to the opposite sex, lead to heart problems in older years.

It is expected that problems with the heart and blood vessels today are the main cause of death. This is stated in the article Australian geneticists in the journal PLoS One.

The researchers found a connection between coronary heart disease and the success of procreation.

The authors recall that the development of most multicellular living beings are governed by two factors – natural and sexual selection.

In the first case, the body evolyutsioniruet under the influence of the environment, and the second evolution depends on intraspecific competition for the opportunity to procreate.

In this fight to win the “bright” individuals that leads to such useless ornaments like peacock tails or scallops roosters, which do not help, but hinder to survive.

The reasons for the existence of sexual selection remain the subject of debate among scientists – the part of biologists believe that it helps the populations to be prepared for sudden changes in conditions, while others believe that such competition protects the species from degeneration and support their competitiveness in the evolutionary “arms race”.

Scientists from the University of Melbourne studied the variations of the DNA of the inhabitants of Europe, Africa, Asia and discovered an unusual connection between these “halves” of evolution that made man genetically and evolutionarily predisposed to developing heart problems and blood vessels in the elderly.

“Mutations that contribute to the development of such health problems in old age, did not disappear from the gene pool, but rather were distributed and accumulated. In other words, the carriers of negative changes in the structure of genes, which lead to the development of coronary disease, left more offspring and more to continue to race”, – quotes RIA Science research.

Scientists believe that some of the changes that increase the attractiveness to the opposite sex lead to heart problems in older years.

In favor of this said the fact that many of these genes were most active in the genital organs or glands, as well as determined the time of puberty, the start time of menstruation, menopause and the likelihood of survival after birth.

All this, say the researchers, suggests that coronary heart disease and other problems of the cardiovascular system prevalent today is not due to the development of civilization and the deterioration of the environment, and for deep evolutionary reasons associated with how our ancestors survived and multiplied in the distant past.

Note, the use of sugar in large quantities increases the risk of cardiovascular disease.
