In 1836, a skull was discovered and believed to be a "godsend", and in the religious atmosphere of the time, it was at the point of a heated debate between scientists and the Bishop of Oxford.
After careful research by Huxley, a professor at University College London, he believed that this was not an uncommon thing, but that it was just an ancient species, and that it was named a "god-given thing" because of the religious atmosphere of the time.
The debate between Huxley and the Bishop of Oxford also revealed the collision of science and religion, which represent different ways of thinking and belief systems, and that the latest research has led to a discussion of human microevolution as the number of additional blood vessels in the human arm is gradually increasing, and the rate of human evolution is increasing.
I. Huxley's Debate with the Bishop of Oxford.
In 1836, a priest sent a unique skull to the University of Bristol in Bristol, which the priest believed was the remains of one of Japheth's sons in the Bible, Hamm, whom he considered a special gift from God.
Huxley was commissioned to investigate the skull, and although Huxley was a naturalist, he was so disgusted by this religious belief that he did not bother with it at first, but the order from above compelled him to study the matter.
Huxley studied the skull in all its aspects, and finally concluded that the ancient species that the priest spoke of was just an ancient species of the ape-man, but the priest did not accept this conclusion.
Huxley studied the skulls in detail and debated them with the Bishop of Oxford.
In Huxley's view, he believed that the skull was just an ancient ape-man, but the Bishop of Oxford believed that it was a "sentient" creature, a gift from God.
So in 1836, Huxley and the Bishop of Oxford had a heated debate, in which the Bishop of Oxford cited many phenomena, and Huxley, as a scientist, also refuted them with scientific theories.
One of them is: "The fact that the skulls of humans and ancient humans are the same size today and this one is relatively large, proves that it is a gift from God."
Huxley believed that this was simply due to the fact that some human races lived in different environments, which also caused the size of the skull to be different.
In Huxley's opinion, he did not think that there was anything unusual about this skull, there were many humans and apes living together in ancient times, so in 1836, this skull was also unveiled under the study of scientists.
This skull comes from a kind of ape-man, and was given a "god-given thing" because of the religious atmosphere at that time, and people's enthusiasm for religious beliefs was also very high, so many people would have a religious understanding of some things.
II. Extra blood vessels in the human arm in 2020.
A 2020 study also showed that humans are evolving, and this study analyzed the extra blood vessels in the human arm.
In the human arm, there are usually only two main blood vessels, one is the ulnar artery and the other is the radial artery, but in some people there are additional blood vessels in the arm, which are made up of the cubital fossa artery and the anal artery.
These two additional arteries are connected to the ulnar and radial arteries, but in the past, these two arteries were used to supply blood to the hand, so in the present human hand, these two arteries no longer exist and have been replaced by the ulnar and radial arteries.
But in some people's hands, these two arteries are still preserved, so in 2020, scientists studied these two additional arteries.
In this study, scientists studied the arteries of the human hand in six different regions, with a total of 1,000 humans involved.
After the analysis, scientists found that the number of extra arteries in the human hand gradually increased, and from the 18th century, the incidence of these extra blood vessels began to gradually increase, and by the 19th century, the incidence of the first extra blood vessels had risen to about 10%.
In the 20th century, the incidence of the first extra blood vessel rose to about 30%, and in the 21st century, the incidence of the first extra blood vessel rose to about 35%.
There is also a corresponding increase in the incidence of the second additional blood vessel, so scientists model data based on this trend, and the incidence will be around 40% in the 21st century.
By the end of this century, the incidence of these two additional arteries will be between 60%~80%, which also indicates that the speed of human evolution is accelerating, and the microevolution of human beings is likely to gradually proceed in these small changes.
3. The phenomenon of human microevolution.
In addition to the gradual increase in additional blood vessels in the human hand, the microevolution of humans manifested itself in many ways.
In the past, wisdom teeth in humans were usually four in one person, but now, many babies are born without wisdom teeth, which is also a manifestation of human microevolution.
The human jaw is also no longer strong and strong, so it can also cause babies to be born without wisdom teeth, as well as one of the reasons for the thinner jaw.
The human face shape has also become shorter, which is also a manifestation of human microevolution, because the human skull has become smaller, which also affects the development of facial bones, so the human face shape will also become shorter.
And human calf muscles are also getting thinner, this is because of the change in human lifestyle, people no longer play the game of running and chasing, so it will lead to weakness of calf muscles.
Fourth, the changes that humanity may face.
Small changes in humanity may be evidence of human evolution, but humanity may face even greater changes in the future.
In the past, scientists have also envisioned that humans may become alien-like forms, based on the idea that humans live in space, and that prolonged microgravity may cause human bones and muscles to weaken, and the face will change dramatically, and human hair may grow longer and skin thinner.
In addition, human eyes will become larger and more adaptable to light, or because humans live in the ocean, human bodies may become fish-like forms, humans will grow fins, their skin will become smoother, humans will breathe like fish, and so on.
However, these assumptions are only the assumptions of scientists, and there is no evidence to prove whether humanity will actually become like this, but there are infinite possibilities for human evolution.
V. Conclusion
The evolution of human beings is a long process, and human beings will continue to explore and change on this long road of evolution, and the future of human beings has infinite possibilities.
