Chapter 503, Genetic Evolution

"Huh!"

Yan Jia was sweating all over, with beads of sweat on her beautiful face. She was very tired at this moment, but she was also very excited. She saw the scene just now clearly. Her understanding of life and genes, and many things that had confused her all along, all disappeared, but at the same time, more and more doubts emerged.

"If only I had held on a little longer just now."

Yan Jia was a little annoyed that she couldn't hold on a little longer. With the cultivation of the Yuanzhu level, it still seemed a little reluctant to activate the Heart of Life, and she couldn't hold on for too long. The Heart of Life was like a bottomless abyss that absorbed her life force.

"Yan Jia, are you okay?"

Sun Xinyuan came up to help her up and asked with concern.

"It's okay, it's just that the Yuan force is exhausted. Just need to recuperate for a while, thank you."

Yan Jia smiled and shook her head.

Because Yan Jia's Yuanli was exhausted, the Empire could not find another Yuanli practitioner who cultivated Life Yuanli to the Yuanzhu level. There were some Yuanshi-level Life Yuanli practitioners, but practitioners at this level had no way to activate the Heart of Life. The Yuanli consumed by activating the Heart of Life was too huge. Even the Yuanzhu level seemed to be struggling. Only when they reached the Immortal level could they do it with ease.

Although they could not continue to activate the Heart of Life to demonstrate the mystery of life for the time being, the scientists of the Empire also gained a lot this time. The scientists of the Empire who personally watched this scene were greatly inspired and had a leap-forward development in their understanding of life.

At the Imperial Institute of Biological Sciences, a large group of masters in the field of biological sciences in the Empire were discussing something fiercely. Although Yan Jia's Yuanli had not yet fully recovered, there was no problem for him to attend some academic conferences. As the founder and Taishan of the Imperial biological science research field, Li Fu naturally could not be absent. Moreover, last time, he witnessed a magical scene with his own eyes, and Li Fu also gained a lot of inspiration and wanted to communicate with other scientists.

"We used to think that gene fragment YX003 belonged to the gene fragment of division and reproduction, but now it seems that we are completely wrong. It should actually belong to the gene sequence of regeneration, which can explain why we have always had problems with the reproduction of new species when we perform gene recombination."

A scientist was expressing his opinion to the virtual image at this time, and the image of a gene fragment in the virtual image was enlarged and played.

The development of the empire's biotechnology technology has actually paid the most attention to the research direction of gene research, because genes are the foundation of organisms. The direction of gene research can be divided into many, such as gene recombination, gene mutagenesis, gene editing, etc. It is obvious that the scientist on the stage specializes in gene recombination.

The world of genes is like the vast universe. Various genes have formed completely different species through complex combinations. However, although the types of organisms are very large and vast, in the final analysis, everything is ultimately determined by genes.

For example, organisms use reproduction. Although each organism reproduces in a completely different way, plants use seeds to reproduce, use cell division to reproduce, birds, fish, etc. use eggs to reproduce, and mammals reproduce in a completely different way.

But in essence, the gene fragments used by organisms for reproduction are the same. They all evolve from a basic initial reproduction gene fragment, and eventually evolve into various reproduction gene fragments such as one, two, three, four, etc.

Another example is obtaining energy from the outside world. The way plants obtain energy is relatively simple and direct. Plants rely on roots to obtain nutrients from the soil and rely on leaves to receive sunlight for photosynthesis; animals basically rely on eating plants or other animals and plankton to obtain energy and nutrients for survival.

Although these two methods are worlds apart, they are essentially two gene fragments evolved from the eating gene fragments. We all know that there are carnivorous plants among plants, such as man-eating plants and man-eating trees. Such plants are also very common in the interstellar universe, and animals themselves also retain some genes that directly obtain the nutrients they need from nature. For example, animals generally need to eat salt, such as cold-blooded animals such as snakes and crocodiles need to bask in the sun to increase their body temperature, etc.

The scientists of the Empire studied genes and then classified and summarized various genes, such as dividing genes into reproduction genes, eating genes, immune genes, perception genes, etc. There are many types, and each major gene can be subdivided into many small genes.

Of course, there are many ways to classify genes. Now there is also a relatively new classification method, advanced genes and low-level genes. This classification is the key to distinguishing advanced organisms from low-level organisms. Scientists believe that the reason why advanced organisms are advanced organisms is that in each gene fragment, the genes of advanced organisms are all primitive genes that have evolved to a relatively advanced stage, and have a large number of advanced genes.

In addition to low-level genes and high-level genes, the scientists of the Empire believe that there are two more advanced genes, namely, wisdom genes and god genes. The wisdom genes are naturally easy to understand. The scientists of the Empire have studied the countless civilized races in the Milky Way. Although the forms of various civilized races are completely different, the differences in wisdom are not too big. Without wisdom, it is impossible to create civilization.

The reason why humans are different from animals is that they have wisdom. Scientists believe that the ancestors of human beings have evolved wisdom genes unintentionally, so humans can continue to prosper.

The scholars and scholars in the humanities field of the Empire have studied the development history of various civilizations in the Milky Way. Basically, scientists of each civilization have conducted in-depth research on the origins of their own civilizations. Almost all civilized races believe that they can create civilizations differently from wild beasts, and almost all believe that there are wisdom genes in their genes.

As for the god gene, this is the result of an inference drawn by the scientists of the Empire from the study of Yuanli and Yuanli practitioners. Advanced Yuanli practitioners have the terrible ability to destroy the world and travel across the universe, while ordinary people who have not practiced Yuanli are no different from ants. The reason for this huge gap, the scientists of the Empire believe, is the existence of the god gene.

Through the cultivation of Yuanli, under the nourishment and cultivation of Yuanli, some low-level genes in the human body will evolve, slowly evolve into divine genes, and thus have all kinds of incredible powerful abilities.

For example, Yuanli practitioners have a very long lifespan, while ordinary people only have a lifespan of less than a hundred years. After research, scientists have determined that all this is actually cell division. The number of cell divisions is limited. When the cell division reaches the limit, people will naturally age and die.

And the natural factor that determines cell division is also genes. This gene is called lifespan gene. Low-level lifespan genes lead to fewer cell divisions and short cell lifespans, so there is a saying that summer insects cannot talk about ice. Most insects cannot live for a year, while relatively advanced lifespan genes can make cells divide more times and have a longer lifespan, so most advanced animals have a longer lifespan.

And the lifespan gene is nourished by Yuanli, so that the lifespan gene evolves and becomes a divine gene. The number of cell divisions can increase infinitely, and the lifespan of the cell itself can also be continuously extended.

Originally, cells may only have a lifespan of 10 days and can only divide a million times, but after evolving to the stage of God Gene, it has a lifespan of 100 or 1,000 years, and can divide tens of millions or hundreds of millions of times, so its lifespan is naturally endless.

Low-level genes, high-level genes, intelligent genes, and God Genes are the four stages of gene evolution, and they are also the four stages of biological evolution. Of course, this is only the current understanding of biology and genes by the scientists of the Empire.

Low-level genes can slowly evolve towards higher-level genes under the promotion of external or internal conditions. Of course, this evolution process is definitely very, very slow, and the time required is calculated in billions of years. There will definitely be countless mutations in this process, and in the end, the fittest will slowly survive, the winners will eliminate the losers, and the excellent genes will be passed down from generation to generation.

This point has been most fully reflected in the evolutionary history of human beings on Earth. Scientists have studied the evolutionary history of human beings and found that at a certain stage, about 2.5 million years ago, there were multiple human races on Earth at the same time, including the Rudolf Man in East Africa, the Homo erectus in East Asia, the Neanderthals in West Asia, and so on.

These human races mentioned here are essentially different from the yellow race, the black race, and the white race. There is already species reproductive isolation between the above-mentioned people, and they cannot reproduce offspring from each other.

But about 20,000 years ago, there was only one race left on Earth, that is, Homo sapiens, which is now commonly referred to as the ancestor of human beings. The reason why Homo sapiens can stand out among many human races is actually due to the wisdom genes evolved by Homo sapiens. Although other human races have many similarities with humans, they have not evolved wisdom genes, and there is still no essential difference from wild beasts.

Under fierce competition and natural elimination, the wise Homo sapiens eventually slowly defeated other human races, adapted to nature better, and finally ruled the earth!
