More and more people choose to have a caesarean section and this is causing a strange 'evolutionary' effect.

"Strange" but does not mean not good. Moreover, do our genomes also be more diverse?

When modern science and technology develops, more and more pregnant women choose a caesarean birth solution. Of course, caesarean births offer many benefits - such as less pain and reduced maternal and infant mortality rates - but there are many medical disadvantages for mothers.

Here, we will not discuss these points. The problem is that according to a recent study, it seems that the tendency to choose caesarean section increases has affected human evolution .

The tendency to increase caesarean birth has affected human evolution.

In fact, in the past, caesarean birth methods were often used only when the fetus was abnormal, unable to be born by natural delivery. However, the study shows that the rate of natural birth defects is increasing, from 30/1000 cases in 1960 to 36/1000 cases at the present time. Look at a little, but that's an increase of up to 20%.

According to Dr. Philipp Mitteroecker from the University of Vienna (Austria), the process of evolution has given a generation of babies more . bigger , because it proves that their health is very good, and their ability to survive. higher. However, the same evolutionary pressure has made the number of mothers with narrow pelvis increase.

With narrow pelvis, women can easily stand upright, better balance, so the rate of miscarriage or premature birth will decrease. The thing when combining the two elements is that it is impossible for babies to be born naturally.

If the baby's head is too big or the pelvis of the mother is too narrow, the baby may be stuck with the frame. In the past, giving birth to such cases is very difficult, can kill both mother and child, and the "narrow pelvis" genome will not be able to continue to circulate.

In the past, births where pregnant women have narrow pelvis are difficult to perform.

"100 years ago, women with narrow pelvis often find it difficult to survive birth. Now, they can transfer that narrow pelvic gene to their children," said study co-author Philipp Mitteroecker. know.

Theoretically, it will change the evolution of humans, because "slightly unfavorable" genes will become more and more widespread. However, this study has no official conclusions, because the evidence is still quite vague, based only on data provided by WHO.

There are many reasons for doctors to have a caesarean section, but it is difficult to classify. For example, in the case of elderly women, they were forced to have a caesarean section because the genitalia was not as flexible as before. Pregnant women with obesity and diabetes will also be assigned to caesarean section.
