Chapter 1105

"Really, I just saw it two days ago. I can't remember how to use it." Wen Xiaoman patted his forehead and was very upset.

"Don't move. The car is going to tip over." Yang Rui clenched the handlebar and rode the bicycle of three passengers at one go. It was not so easy to ride.

Moreover, Wen Xiaoman is drilling into his arms, and Xie Lei in the back holds him tightly. It seems that driving the car is more difficult.

After listening to Yang Rui's words, Wen Xiaoman felt a little better, but he recalled for a moment. He raised his neck, and the warm breath sprayed into Yang Rui's ears and said, "I remember. It's about the origin of human beings. My father said it's a very important research topic, right?"

Yang Rui was a little dizzy by the girl's unique sweet smell. He reacted in a flash and said in surprise: "human out of Africa? Now it's out? "

"Why? You know Wen Xiaoman straightened his chest in surprise, but his lips almost rubbed Yang Rui's ears. Maybe he rubbed the hair on his ears, which made his heart itch.

Yang Rui's heart swings. He quickly pretends to ride hard and says seriously, "it's a serious topic for human beings to go out of Africa. I've heard of it."

The origin of human beings is not only a serious topic, it is an important topic, especially for the biological community in the 1980s, it is more concerned than HIV.

This is mainly because the topic of human origin has a very heavy social attribute. Moreover, there is no doubt that the topic of human origin is an important issue for any country and any race.

The three important issues of philosophy are where I come from, who I am and where I am going.

The origin of human beings is the biological answer to the question "where do I come from?".

And this answer, in the 1980s, may not have been pleasant - because DNA testing by PCR showed that humans originated in Africa.

Compared with previous guesses, DNA testing by PCR is more authoritative and unexpected.

For the self conceited white people and the proud yellow people, the answer they prefer, or they prefer to accept, is the theory of multiple origins of human beings, that is, human beings were born in many places on the earth at a similar time. In the 21st century, some people still insist on this theory.

However, the mainstream argument, since the invention of PCR, is that "human beings originated in Africa".

This answer is also a concentrated appearance of PCR in the world, which can be said to be a successful practice of PCR in interdisciplinary.

Compared with police detection or academic achievements, the news of human origin in Africa is obviously more sensational.

It is conceivable that in a long period of time, relevant news will become the headlines of major news media, not only in the United States and the United Kingdom, which are technologically advanced countries, but also in China and Kenya, which are underdeveloped countries.

There are not many academic achievements that can reach this level.

Yang Rui was so excited that he could not help pedaling fast.

"Be careful" Xie Meng sits in the back, feeling the wind whirring in her ears and exclaiming.

But Wen Xiaoman chuckled twice and yelled, "there's no one in the alley. It's OK."

Yang Rui slowed down his pedaling slightly and asked, "Xiaoman, where do you see the news of human walking in Africa? Which newspaper did you cut it from? "

"I kind of forgot. Or come to my house and I'll look for it? " Wen Xiaoman is like a fan trying to lure Aidou to his home, nervous and excited.

Yang Rui shook his head and said, "I'm afraid I can't. I still have something to do today."

He was too lazy to go again.

Moreover, it's strange to go to other girls' homes.

Wen Xiaoman doesn't feel sorry for the failure of the brainwave plan. He just continues to shrink in Yang Rui's warm arms and chat with each other, hoping that the bus station will be further away.

Unfortunately, the public transportation system in the capital has always been dense. Not far from the entrance of the hutongs, you can see green buses coming and going. Some buses are one-to-one buses with rubber hinges in the middle. One car can pull hundreds of people.

"Here we are." Yang Rui rubbed his feet on the ground, and his habitual bicycle brought him to the front again, and then stopped.

Wen Xiaoman reluctantly jumped down from his bicycle and suddenly remembered: "otherwise, I'll take the briefing to your dormitory tomorrow."

"I don't have to be in the dorm." Yang Rui said that he couldn't bear Wen Xiaoman's disappointment. Moreover, he really wanted to read the newspaper clippings and said, "well, let's make an appointment to my lab, ion channel lab, which is in Peking University. If you have time to come over one day, please call me...""No, I'll go tomorrow." Wen Xiaoman is as happy as a fan who got the picture of Aidou.

Her age, if she is a Star chaser, is a serious age.

And Yang Rui is much better than ordinary stars in terms of appearance and social performance.

"I'll be in the lab until 6 p.m. tomorrow to see when you can come over." Yang Rui said for a moment, asked: "if you are in the middle school attached to central sound, you will have class tomorrow?"

"It doesn't matter. I can get leave." Wen Xiaoman is not in charge of such trifles as class.

Yang Rui hesitated for a moment and said, "it's better not to ask for leave as much as possible. It's also very important to have class."

As a person of the 1980s, it's really very important to take classes, especially for art students. The level of education and background are the same, which means the difficulty of the road in the future. Students who graduated from Beijing film studio or CCTV have their way to do serious art or enter the entertainment channel. However, it's much more difficult for mass actors who have no education background to become stars, and they have to guard against their wives and agents wearing green hats together.

In the same way, different people have different effects.

For example, Wen Xiaoman's parents, if they stand in Yang Rui's position now and ask her to study hard, most of them will get the hum of rebellious period.

However, when Yang Rui said something similar, Wen Xiaoman was moved by his concern and said seriously: "I usually study hard. Tomorrow's course doesn't matter. In the afternoon, it's just art and body."

Said, Wen Xiaoman casually bent a leg, with a hand pull, to lead to the back of the head position.

Yang Rui was stunned. Such a powerful Laurie just jumped out of the second dimension.

"My physique class, the teacher is to let me free activities." When Wen Xiaoman was talking, the bus came. She quickly stepped on the bus and stood in the open space by the window, waving goodbye to Yang Rui.

Yang Rui stepped on his bicycle again, feeling better and riding a little faster. When he got to the laboratory, he called professor darbeco from abroad.
