Orange Blossom is a bit sweet

Chapter 216 Epigenetics

After Xiaocha and Bai Yu went downstairs to the team kitchen, Li Cheng was left alone in the attic, and she could take a nap for a while.

Before closing her eyes for 2 minutes, she suddenly straightened up, pulled out the chat software and sent a message to her cousin.

[Princess Orange Blossom]: Sis, I want to ask you something.

[Classmate Taozi]: Huh?Please say.

The cousin actually replied in seconds, and Li Cheng felt a sense of shuddering. It may be a coincidence that the other party just came home from get off work to rest.

[Princess Orange Blossom]: That's it, uh...

[Princess Orange Blossom]: I have a friend. She grew up abroad and grew up in China. She looks like two different people. She is obviously the same person, but how can there be such a big difference!
[Student Taozi]: To be more specific, for example, where did she live abroad before, and where did she live after returning to China?About how long does it take for a big change in appearance?

Li Cheng also doesn't know if Xiaocha brought Bai Yu back when Jian Man decided to adopt him. It is estimated that if this is the case, then Xiaocha should have only lived in France for 3 years. When she was pregnant in France, she should be 4 years old.

She didn't have time to return to her cousin's information, but turned it up and turned on her desktop computer.

Opened the hard drive to check her past photos, but it was completely beyond her expectations. Xiaocha came back to China with her brother since she was 3 years old, but she was with her parents!
With parents!
Bai Yu and Xiaocha's parents, Bai Wenxi and Jian Ning, are still alive and well.

His father did not engage in journalistic investigative work when he graduated, nor did he work as a foreign correspondent and then went to work in France, but directly passed the examination and entered the Ministry of Foreign Affairs.

Xiaocha was not born in France either, she was born in Zambia, and Jian Ning was in Zambia throughout the process of conceiving Xiaocha.

Xiaocha returned to China with her parents before Bai Yu went to elementary school after she was 3 years old. Bai Wenxi was transferred to the Jiangcheng Consulate General as an administrative staff, while Jian Ning and her younger sister Jian Man settled down in Jinling. After Jian Ning returned to China Engaged in the ISO90001 third-party certification of foreign-funded enterprises in the territory, specializing in import and export trade service outsourcing, is Ji Chong's partner.

Li Cheng saw the family portrait of Bai Yu's family of four on his hard drive, and Bai Yu also met himself and Ji Yingduo when he was 6 years old.

Since Bai Yu became a member of the team, Bai Yu's family will meet in Jiangcheng every weekend.

This is a world that is really friendly to Bai Yu.

Li Cheng was a little overwhelmed, and her hands were shaking a little.

[Student Taozi]: Little Orange?

[Princess Orange Blossom]: Oh, oh, here I come, uh, I'm actually fine, but I want to say that my friend was born in France before, and has been living in France, her hair color, eye color and The skin is very similar to the French, but after the same time when she returned to China, she didn't look like the French at all.

[Student Taozi]: Oh, this is very normal. The external environment, food, and temperature will completely change a person’s appearance, especially in places where the latitude gap is particularly large.For specific research results, you can refer to the monograph on epigenetics.

[Princess Orange Blossom]: I don't understand?
[Student Taozi]: For example, aborigines born in tropical regions have never had the genetic disease of high blood pressure, but after living in frigid regions, blood pressure, blood lipids, and blood sugar all rise sharply, and finally become a group of three highs. It belongs to the category of epigenetics.

Li Tao found that typing was troublesome, so he turned it into a voice message: "The direct reason for becoming a three-high group is that the body needs to accept such changes due to external environmental stimuli, and DNA transcription is an adjustment made to allow the human body to cope with extreme environments.

People living in alpine regions need high blood lipids to maintain the vitality of the heart, just like nitroglycerin is always stored in the body, to prevent the heart from sudden arrest due to external extreme cold weather stimulation.

Of course, this example is an extreme case.

Let me give another example of universal research significance, which is now at the forefront of epigenetics research-the improvement of human IQ by nutrients.

Today's children are generally smarter than 10 years ago, because the large intake of folic acid makes the mother feel that the era of mildness and nutrition is coming, thus opening the expression of wisdom genes.

The specific manifestation is that after the fetus receives a large amount of folic acid stimulation, the genes of the developing brain are more intelligent in order to cope with the nutrient-rich era. Human beings have a deeper mechanism for socialization and intellectual cooperation under nutrient-rich conditions, and folic acid-related intelligence genes Expression was activated, leading to a significant increase in the average IQ of the children over a short period of time. "

[Princess Orange Blossom]: Huh?That probably has nothing to do with folic acid, which means my friend has a genetic mutation?
Classmate Taozi: "Of course not, the change of your friend's appearance also belongs to the category of typical epigenetics.

When she lived in France, she was affected by the synergistic effects of France's high latitude, mid-temperate zone, mid-temperate zone food, and medium-temperate zone light intensity. She behaved closer to the French group, and even resembled the Europa race because her mother was in France when she was pregnant.

Even if your friend carries the standard Asian gene, it is very likely that because the mother lived in France for a long time during pregnancy, she will look like the local French.

However, after returning to China, living at a relatively low latitude, subtropical food, and subtropical light synergistically, they will completely behave like Asians.

The external environment will continue to change the pigments secreted by the human body, protein synthesis, and skin color, especially the food eaten by the mother during pregnancy, the water she drank, and the intestinal flora are significantly related to the shaping of human facial appearance, which is why there are Many couples will have a husband and wife phase after living together for many years.

People's different regions will directly change her appearance, which is a natural adjustment made by the body to adapt to the local environment.

This is the so-called 'subtle influence', and it is real in genetics. "

Li Cheng didn't expect that human beings have such perfect genes that they can adapt to the environment like a chameleon?

[Princess Orange Blossom]: Then aren't we all chameleons?

[Student Taozi]: "Hehe, it's higher than a chameleon.

The environmental adaptation of the chameleon is limited to the surface color of the body skin, and its ability to adapt to other natural environments is far less than that of humans.

Human beings’ appearance gene adjustment is all-round, from skin color to appearance, from intestinal flora to blood pressure, from temperature to latitude, from behavior to overall IQ, all will change due to adaptation to the environment.

According to the global IQ measurement, the average IQ of the yellow race ranks first in the world, even surpassing the average IQ of the Jewish race. This is also related to the complex and drastic changes in the evolutionary environment of the yellow race in frigid, mid-temperate, and subtropical regions during the evolution process. relation. "
