Reproduction is a major event for both humans and animals.
Only with childbirth can there be continuation, and with continuation, there is hope. However, based on relevant experience, it seems that it is easier and easier for animals to have offspring than humans. Human beings, on the other hand, need to go through a long and arduous process, especially the pain caused by childbirth, which can even make the mother unforgettable for a lifetime.
The vitalism of human beings
Mammals are generally viviparous, such as humans, tigers, pigs, cats, giant pandas, etc. Viviparity refers to the birth canal after the fertilized egg is fully developed in the uterus.
The fetus obtains nutrients from the mother, mainly through the placenta and umbilical cord. The fetus is warmly wrapped in the mother's womb and amniotic fluid, which receives nutrients from the mother and excretes metabolites directly into the mother's body.
For human beings, the moment a woman becomes pregnant, the great identity of "mother" creeps in. The woman's body provides all the safe and reliable conditions for the growth of the fertilized egg. Throughout pregnancy, the mother works tirelessly to provide nutrients to the embryo. At that time, the embryo was like an "invader", attached to the uterine wall. The mother will have morning sickness reactions such as vomiting and dizziness.
In the late stage of embryonic development, it has developed into a "little person" in the mother's body, and the weight and nutrient consumption at this time are no longer the same, and it is conservatively estimated to weigh 5 to 10 catties. Pregnant women in the third trimester often "support" a "huge belly", and it is very difficult to eat, wear, travel and lie down.
When the fetus matures, it sends signals to the uterus, causing the water to break up and contractions to varying degrees. At this time, the mother will experience intense pain. In ancient times, an experienced midwife was usually arranged to deliver the pregnant woman, instructing the pregnant woman on the rules of exhalation and exhalation, and how to exert force.
In modern times, doctors will also provide scientific and mature delivery guidance and care for women who give birth naturally, and escort the safety of pregnant women throughout the process. But it still can't avoid accidents in the production process, as well as heart-rending pain.
Although humans have evolved into the most advanced creatures in nature, they are slightly inferior to most animals in terms of reproductive ability and production process. Modern people love to supplement nutrition and exercise too little, resulting in the phenomenon that the fetus has a large head and a strong body before birth. However, because of the small pelvis and narrow birth canal, the delivery of the fetus is particularly difficult.
The production of animals "with ease".
Problems such as "difficult delivery" and "painful delivery" have given rise to painless techniques and caesarean section techniques, which can relieve the pain of pregnant women during childbirth to varying degrees, but still have to endure inhuman pain during waking moments.
However, these problems are not seen in most animals. The tigers, leopards, and whales in the zoo are all produced in-house. When the cubs are delivered, animals such as tigers and leopards will lick the afterbirth clothes on the cubs as soon as possible, and do a good job of cleaning and keeping the cubs warm. Breeders are usually responsible for logistics.
Domestic pigs, cats, dogs and other animals not only have a short pregnancy period, but also rarely need human help in the production process. Moreover, they are capable of giving birth to several cubs in a single litter. It is worth mentioning that domestic animals also have prenatal labor pains, which in the case of non-difficult births, disappear quickly after the delivery of the cubs.
The mother of the pups is also able to eat faster, regain strength, and secrete milk to feed the pup.
When it comes to production, animals in the wild are even better. In order to avoid the detection of natural predators, wild mammals usually do not make too much noise when giving birth, and some animals with high vigilance even "muffled production".
Wild animals like zebras and elephants can even walk and give birth at the same time. Due to evolutionary reasons, the cubs born to these animals are able to walk autonomously and closely follow their mother's steps shortly after they land. 、
The reason why human childbirth is more painful than that of animals
Scientists speculate that one of the reasons why human childbirth is several times more painful than that of animals is that due to the upright walking mechanism of humans, women's bones have become narrower and narrower in the process of evolution, resulting in painful and difficult delivery of the fetus.
Biologists have studied the pelvis of humans for a long time, as well as the pelvic bones of human relatives chimpanzees. Through comparison, it is found that even if the "close relatives", the human beings who walk upright, the pelvic bones of the female group appear very narrow and cramped, and the birth canal is more rugged.
Most animals walk on four legs, the limbs are evenly stressed, and the delivery of the young is not limited by bones, and the delivery process is relatively easy. But not all animals are produced so smoothly. For example, if the combination of a large male dog and a small female dog is successful, it will cause great difficulties for the female mother to give birth due to the genetic reasons of the father.
The same can happen in hybrid animals, such as the Belgian Blue Cattle, which is more difficult than humans.
Due to the lack of myotin due to genetic mutations caused by crossbreeding, the Belgian blue cow fetuses grow particularly fast in the mother's womb, making delivery difficult. In the process of production, we need the companionship and help of humans. If the Belgian blue cow has a difficult birth, humans also need to perform a "caesarean section" operation for the mother in time to ensure the safety of the fetus and the mother.
Is it really inevitable that humans will have pain during childbirth?
Due to the latest iterations of midwifery technology, as well as scientific advances, eligible pregnant women can choose to have a "painless delivery". The pain of childbirth is mainly caused by contractions, as well as pain caused by perineal tears. Although this kind of pain hits the "Tianling Gai" when it hurts, it is not a continuous pain, but a regular and intermittent pain.
According to these laws, a series of scientific methods of childbirth have been derived. Non-pharmacological analgesia includes mental comfort, breathing, and water delivery.
Pranayama was most commonly used by experienced midwives in ancient times. Among pharmacological analgesia, the most effective and safer method is neuraxial labor analgesia. With the escort of advanced technology, the mother is conscious, painless, and able to give birth in a better state.
For affectionate human beings, children are not only the continuation of genes, but also the crystallization and testimony of parents' love. Perhaps it is the incomparable birth significance of human cubs, so the mother needs to pay more hardships in the process of giving birth to protect this unique life, thank you for reading.
