From a scientific point of view, human body function is not as good as most animals, if it is not relying on wisdom and hands, human beings are still at a disadvantage in the world of the weak and the strong, and now, although human beings have successfully climbed to the top of the food chain, they have become the masters of the earth.
But human beings are still a long way from evolving perfect forms, so if the advantages of most animals are concentrated on humans, what will the appearance of this human being be? Scientists have given a human model that claims to be the "perfect human body," but the physical object is a big surprise.
British biologist Alice Roberts and Roger Haiffel, director of the Science Museum in London, challenged to create the most perfect human model in three months, and as a result, a human appearance that was even more peculiar than in the science fiction movie Avatar appeared.
The supposedly perfect body model is modeled after a human female, with the retina of an octopus, the ears of a cat, the spine of a chimpanzee, and the nursery bag of a kangaroo, as well as the "big long legs" of an ostrich.
Anthropologist Alice believes that although the human eye structure is better than most animals, but it is not the most perfect of all animals, the human retina is mainly composed of three layers of cells, namely photoreceptor cells, bipolar cell concave and ganglion cells, but theoretically, in order to better perceive the light source, the photoreceptor cells should be located in the outermost layer, and the ganglion cells are located on the inside, in order to quickly transmit light signals to the brain.
But the structure of the human retina is just the opposite, and because of this, when all light enters the pupil, it must pass through the nerve fibers of the ganglion cells to gather into art, and finally penetrate the eyeballs to the brain, so that the human perception time of the light source not only increases, but also leads to an area in the human retina that cannot be sensed, which is what we commonly call "blind spots".
In the eyes of scientists, the human eyeball design is that the designer accidentally took the drawing backwards, and the octopus's eyeball design is "correct", the octopus's photoreceptor cells can face the light head-on, and the blood vessels and nerve fibers are located behind the photoreceptor cells, that is, the world in the octopus's eyes is not "dead ends".
In addition to the key organ eyes, the highest sound frequency acceptable to the human ear is only about 20,000 hertz, and the hearing ability of felines is significantly better than that of humans, more than 50,000 to 60,000 hertz, so even cats that survive in harsh environments in the wild can judge the location of their prey based on subtle sounds.
Moreover, unlike the fixed structure of the human outer ear, the muscular structure of the cat's auricle is more developed, and they can easily rotate the ear more than 180 degrees, which not only allows the cat to collect sound in all directions without dead ends, but also amplifies the sound they hear according to the needs, and does not have to worry about the hearing will be weakened by age.
Long and flexible spines can help us run faster, and we consume less energy than limb-walking primates, but the disadvantage is that the spine is also under more pressure, and as we age, humans are more likely to have lumbar disc herniation or sciatica problems.
Based on this, anthropologists decided to emulate the chimpanzee's vertebrae function, the vertebrae of the "perfect human" were reduced to 4, the patella wings of Pangu became wider in order to give the body more support, and for the human spine that looked a little deformed, anthropologist Alice thought it was completely worth it, at least we avoided the pain of the lower back.
For human women, pregnancy and childbirth are extremely painful, but kangaroos never have this trouble, because kangaroos are fetal animals, but they do not have a real placenta.
Kangaroo babies have been born in about a month of fertilization, although still very fragile, but the wallabies will consciously crawl to the mother's belly pocket from the moment of birth, the kangaroo baby who stays in the mother's belly bag can not only get safety, but also by sucking the milk in the mother's belly bag to obtain nutrition, and by placing the fetus in the nursery bag, the feeding method can effectively alleviate the birth difficulties caused by human expectations.
Running faster has always been a dream of mankind, and the fastest creatures on land are the cheetahs, with an average running speed of 90 kilometers per hour and a maximum speed of 110 kilometers per hour, although it can only last about five minutes.
In terms of human current sprint records, Bolt's 9.58 seconds created at the Berlin World Championships in 2009 is poorly calculated to be about 10 meters per second, but the creatures that can really run fast over long distances are not humans or cheetahs, but ostriches known as "big long legs" in the biological world.
The average speed of the African ostrich is 65 kilometers per hour, and according to this speed, it takes an adult only 40 minutes to run a 42-kilometer marathon, which is much better than the kenyan Pujog, who currently has the best marathon record holder, 1 hour and 59 minutes, so anthropologist Alice believes that the perfect human body must have such long legs.
For the perfect human body, Alice believes that more inspiration can be drawn from other animals, but this is only an idea, human evolution has never been a process that can be chosen independently, otherwise we would not have to invent airplanes and ships, but in the future, human beings will evolve into a novel appearance, which is worth waiting to see.
