Einstein's theory of biological evolution clearly put forward in the new century 19 belongs to a milestone scientific theory, which unlocks the regularity of the development trend of life on earth and gives a practical guidance to the problem of human origin. According to the theory of biological evolution, the starting point of all populations is simple microorganisms, and then they gradually become complex in the whole process of constantly adapting to the new environment. Primates are the most typical examples. This microorganism not only produces a population like apes, but also produces a population like humans.
Therefore, many seemingly dissimilar populations in nature are likely to have the closest evolutionary relationship. Can two populations like that produce offspring according to hybridization? The answer is basically no, even if they can give birth to hybrid offspring, the offspring will still have the problem of infertility or short cycle, for example, tigon, a hybrid of liger, and an ass, a hybrid of a horse and an ass, cannot give birth to the next generation.
The closest animal associated with human beings is the gorilla, so the question is, can people cross with gorillas to give birth to all normal offspring?
How similar are humans and gorillas?
Although people and gorillas seem to have great differences in appearance and habit formation, an elite team of scientific research conducted an in-depth analysis of the genetic genes of people and gorillas and found that the genetic similarity between them actually reached 99.4%. This scientific research was published in the Proceedings of the National Academy of Sciences by Raymond Goodman, a scientist from Wayne Rice University in England, and an elite team. They selected gorillas, chimpanzees, mice, humans and ordinary monkeys as the research objects.
During the research, biologists sequenced the transcriptome of functional genes of five experimental targets and identified 97 functional genes. According to the test data, gorillas are 99.4% similar to humans in the DNA sequence of 97 functional genes here, so they clearly put forward in their graduation thesis that gorillas should be defined as "brothers" in the whole process of human evolution. In addition to the similarity of genetic aspect ratio, the description of gorilla's psychological activities and group status is also very similar to that of human beings.
When it comes to gorillas, we can't help but mention the primate biologist jane goodall. She has lived with gorillas for decades and gained a lot of first-hand information about their scientific research. In Goodall's observation, there are also politics and politics in the gorilla population. She defined these leading male gorillas as Erffa species. This Erffa gorilla has its own characteristics. Some gorillas are smarter, others are more ignorant. Some are gentle, others are tyrannical.
However, all kinds of gorillas in Erffa have one thing in common, that is, they have the ability to create an alliance Internet, which is very similar to human society. The similarity between humans and gorillas is also reflected in the fact that gorillas can mainly show personal behaviors and postures similar to humans, such as using natural objects as special tools to obtain food. Gorillas will continue to kill each other for better partners or status. If people tend to behave in a civilized way, they may also behave like gorillas.
"_ Crazy former Soviet biologist Ivanov had planned to do experiments?
Even if people and gorillas have such similar areas, if people cross with gorillas, can they get hybrid offspring? This idea sounds crazy now, because it has completely violated people's social morality. But at the beginning of last century, a biologist did try to carry out the experiment of ape hybridization. He is the former Soviet biologist Ilya Ivanov. I heard that Ivanov's idea was finally audited to the level of the former Soviet Union. What is their purpose?
There is a saying that their purpose is to create elite apes that are stronger and smarter than humans. They can be used to enrich troops and as human capital. After being audited, Ivanov led his little assistant to Africa to look for gorillas on 1926. Their first address went to Tanzania, but they didn't know they had everything there. Tanzania or Holland became a colony in the 1920s, so Ivanov went to Paris to wait after his first unsuccessful search.
After waiting for about eight months, it was reported that gorillas had been found in Tanzania. Ivanov immediately took his little assistant to Tanzania to catch them. With the help of local people, Ivanov's elite team caught 20 gorillas at a time and transported them to Paris, France. In Paris, France, Ivanov gradually developed his ape hybridization experiment. He first took out the male sperm and injected it into the bilateral fallopian tubes of the female gorilla.
What is the final result of the experiment?
However, no matter how hard Ivanov tried, he could not get satisfactory results, and the first experiment failed. Later, he gradually changed his experimental thinking and asked the male gorilla to give male sperm, and then injected it into the bilateral fallopian tubes of people and women to try to get pregnant. If this experiment is put into practice today, it will surely be reprimanded by the whole world. However, in an era when everyone is likely to have enough to eat, not many people care about this kind of experiment involving social and moral issues.
You might think that some women would be stupid enough to give Ivanov a test target, but Ivanov not only found young female volunteers, but also found five. Just as he was preparing to conduct the second experiment in Paris, France in advance, the Dutch governor flew into a rage after hearing this experiment. He felt that this experiment completely ignored people's self-esteem, so he ordered Ivanov to be driven away. In desperation, Ivanov took only 20 gorillas and set foot on the road of the former Soviet Union again. Sadly, all these gorillas died on the road.
So _ Ivanov _ crazy idea is finally finished? The answer is _ yes, because Ivanov was finally exiled, and he had a chance to return to the former Soviet Union in his later years.
Is ape hybridization feasible in theory?
Bian Xiao felt that even if Ivanov had a chance to carry out the ape hybridization experiment in his own country, the material he made could not survive or reproduce in the end, because in fact, humans and gorillas are reproductive isolated. This is reflected in the difference in the number of sex chromosomes between humans and gorillas. People have 46 sex chromosomes, while gorillas have 48 sex chromosomes. As mentioned above, humans and gorillas are very similar in genetics, and this fruit was also obtained from a part of high-throughput sequencing.
In other words, there are mistakes in the similar names of the aspect ratio of human and gorilla genes. How else can you explain that a genetic error of 0.6% will lead to such a big difference between humans and gorillas? Just looking for some relevant narratives in historical time, the probability of this kind of experiment in the future is also very small.
