New studies have shown that Caesarean births have a significant impact on human evolution. Nowadays, more women with narrow pelvises need C-sections to be able to deliver their babies. Researchers have proved that the number of Caesarean births has increased from the 1960s where 30 out of 1,000 births per day were to 36 out of 1,000 births nowadays.
- Nowadays, C-sections became a trend rather then a necessity.
- Some specialists argued that during human evolution the pelvis seems to not have developed enough.
Historians argued that these particular genes could not have been transmitted from mother to child because both of them would have died during labor. Some scientists from Austria have claimed that this unhealthy trend of delivering babies through C-sections will most likely continue. What is more, caesarean surgeries will not become that popular to determine natural births to completely vanish.
Dr. Philipp Mitteroecker, who is responsible for the department of theoretical biology at the University of Vienna, has argued that there were some questions regarding the understanding of human evolution which remained to be answered. He asserted that experts could not establish yet the cause of fetopelvic disproportion which has been lately increasing in numbers.
All these cases where babies cannot fit through their mother birth canal are becoming more frequent, without doctors having a proper explanation for it. If people do not benefit from modern medical intervention, this type of disproportions can cause major problems for both the mother and the baby, even becoming lethal.
A hundred years ago, women with a narrow pelvis would not have been able to survive birth. Nowadays, women manage to give birth by using the new technology, having the advantage of a C-section. Unfortunately, these women usually pass on their genes to their daughters who will also be born to develop a narrow pelvis later.
Specialists have explained that the head of a human newborn is larger than the head of any other baby of other primates. For example, it is relatively easy for chimps to give birth. Researchers have gathered data from the World Health Organization and previous birth studies to find out why human pelvis did not become wider over the years.
One study has revealed that there is a trend in the larger newborns which are more robust and healthy but are also too large to be born in a natural way. They can get stuck during labor. Another side of this selective method is that many women who are carrying smaller babies are also tempted to use a C-section. This trend is not considered to be healthy. If they can give birth in a natural way, specialists argued that these women do not need the help of technology.
