Chapter 1292 The Evolutionary History of Genes
There is a very strange legend between humans and orangutans. Some people claim that the genomes of the two are 99% similar, but this legend is not true.
But there is another key understanding in the knowledge that Gu Qing received, that is, as primates, orangutans are more keenly aware of environmental problems than humans and express them in real-life activities.
So after establishing the special equipment research and development center, Gu Qing guided the special flight equipment pilot function research laboratory to develop step by step in the direction of animal orangutans.
The ultimate goal is to let orangutans live on the moon base with the early astronauts, so that the aerospace department, biomedicine department, and life medicine department, which have high confidentiality, can work with the Titan star department to design Technical system products that ensure that ordinary humans can live a normal life on the moon.
Looking at the organs of some male orangutans in the life-sustaining cradle, Gu Qing asked the person in charge to notify other idle scientific researchers to gather.
He will not disturb those R&D personnel who are immersed in scientific research work, because if it affects the progress of the other party's project or even interrupts some fantastic ideas, that is something that all scientific researchers at Jiuzhou Technology cannot do. Accept the painful torture.
After all the idle professors, masters and PhDs gathered in the laboratory, Gu Qing looked around and saw some people running out of breath, and said with concern: "The body is the capital of the revolution, everyone is here You must take good care of yourself in your daily life and work Stay in shape, exercise more, and pay attention to a balanced diet.”
After hearing this, the several R&D staff who were still out of breath immediately straightened their chests and began to take deep breaths, unwilling to give this person any advice. The top star in the scientific research community leaves a bit of a bad impression.
After everyone's breathing stabilized, Gu Qing picked up a pen on the test table next to him and tapped the spiral genome behind him.
He said: "Actually, from the perspective of the structure of the genome, we humans, like orangutans, are highly complex primates. Unlike the simple genomes of simple eukaryotes like yeast, our genomes are very complex, even complex. There are a lot of designs that are useless, but that’s all they look good. Already.
Now the academic community has begun to demonstrate to the public the editing and combinatorial regulation of coding genes for various purposes, not only to assist a limited number of genes to achieve quite complex expression patterns, but also to deliberately create complex expression patterns for certain genes. Genes with special effects on environment and disease
Everyone. They are all scholars in related fields, and they all know that for complex living organisms, genes are not content that can be edited and edited at will like videos and copywriting.
It is difficult for us to understand why at first. Our human genome only has more than 20,000 genes, which is only one more than those of insects. It’s just a little bit, but it can achieve more functions than animals with the same number of genomes.
And according to the current genetic testing data, the genome sequences of all known major organisms in the world are roughly similar to those of humans. Seventy to ninety percent.
Three percent of the genome sequences of humans and orangutans are incomparable. According to observational data obtained through current scientific and technological means, only about 70 percent of the genome sequences are similar, and they are not identical.
Please note that what I have always said is similar, similar. I have always had great interest in biomedicine, genetics, neural signals and other subjects, so you can rest assured that I am not a layman who comes to chant sutras. , and I’m not here to interfere with everyone’s experimental projects. ”
Throw out some knowledge points, and then reveal some of your knowledge reserves.
Gu Qing noticed that the cautious looks in the eyes of many R&D personnel present had weakened a lot, but they had not disappeared yet.
So he continued: "The difference of about 30% allows us and orangutans to develop into two civilizations.
From the perspective of evolution from orangutans to humans, from monkeys to humans, and even from the perspective of the evolution of immortal fish, turtles, immortal jellyfish and other species in the sea, nature’s survival mode of natural selection has allowed the genes of life to never stop evolving. . After our company's bionic mechanical prostheses began human experiments, our researchers found that ordinary people who have been trained to use smart products for a long time have slightly more mutated brain genes than ordinary people who rarely use smart electronic products, and This part of the gene mutation has no side effects so far.
In academic circles, there is a concept of ‘primate deceleration’, which believes that the genetic evolution speed of our primates is slowing down, and even some functions are degenerating.
One of our official cooperation projects with Daxia is to work with other research teams to deduce a phylogenetic tree at the whole genome level of modern primates.
In the deduction of this developmental tree, some scholars have proposed that the most recent common ancestor of our primates should have appeared about 64.95 to 68.29 million years ago, which is the same interval as the Cretaceous-Tertiary mass extinction. The events coincide.
It is believed that the early radiation of primates may have been affected by the Cretaceous-Tertiary mass extinction event. Even when the research team reconstructed the chromosome structure from the common ancestor of primates to the modern human genome, they found that the ancestors of primates are closely related to our modern Humans share conserved karyotypic characteristics.
At the same time, the research team also found that different primate ancestors had different levels of genome rearrangement rates. In the ancestral branch of the great ape, an overall increase in the number of genomic element variation levels was found.
For example, our genes for brain capacity, body shape, camouflage hair, etc. all have varying degrees of variation
“From the perspective of biological evolution, the higher-level species , the larger its brain capacity is, which proves that the brain is not only important in general subjects, but also related to various things. The various functions that species can achieve are directly related.
The brain capacity of African ancient apes is only 452 cubic centimeters, while our modern humans have a brain capacity of 1000 to 1500 cubic centimeters. The relative brain capacity of humans is. More than three times that of apes, allowing us to have more thinking ability
Biological evolution is not the guidance of God, but the efforts of us humans, step by step growth, one-to-one mutation of genes, and a little increase in brain capacity.
For millions of years, we humans have been racing against God to evolve.
Even with the blessing of various smart devices and neural conversion devices, this evolution has not stagnated, but is accelerating. ”
As Gu Qing narrated, the eyes of more and more researchers became deep and excited.
Scientific researchers are also human beings, they are not stones without emotional fluctuations.
Looking at the various experimental samples around them, their minds could no longer calm down.
But at this moment, Gu Qing suddenly snapped his fingers.
