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

"Don't move, the car is going to fall down." Yang Rui squeezed the handlebars and rode on a three-passenger bicycle at once. It was not that easy to ride.

Moreover, Wen Xiaoman was drilling into his arms, while Xie Lei behind him hugged him tightly, making it more difficult to drive the vehicle.

Wen Xiaoman felt a little obedient after listening to Yang Rui's words, but it was a moment of recollection. He raised his neck and sprayed a warm breath into Yang Rui's ears and said, "I remember, it's about the origin of mankind. Dad said it is very important. Research topic, right?"

Yang Rui was a little dizzy by the girl's unique sweet fragrance. He reacted in a flash, and said in amazement: "Humans are out of Africa? Are they coming out now?"

"Huh? You know." Wen Xiaoman straightened out his chest in surprise, but his lips almost touched Yang Rui's ears, perhaps it touched the hairs on the ears, which made his heart itchy.

Yang Rui shook his heart, and hurriedly pretended to ride hard, and said earnestly: "Humanity out of Africa is indeed a serious topic, I've heard of it."

The origin of mankind is not only a serious topic, it is an important topic, especially for the biological community in the 1980s, it was a topic that received more attention than HIV.

This is mainly because the social attributes of the topic of human origin are extremely heavy, and there is no doubt that the topic of human origin is an important issue for any country and any race.

The three important questions of philosophy, where do I come from, who am I, and where do I go.

The question of the origin of mankind is the biological answer to the question "Where do I come from".

And this answer, in the 1980s, may not be likable-because the DNA test done by pcr shows that humans originated in Africa.

Compared with the various guesses before this, the DNA test using pcr is more authoritative and even more unexpected.

For the pretentious white people, for the yellow race proud of history, the answer they prefer, or the answer they are more willing to accept, is the multi-origin theory of mankind, that is, mankind is in multiple places on the earth. , Was born 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".

And this answer is also a concentrated appearance of pcr worldwide, which can be said to be an interdisciplinary successful practice of pcr.

Compared with the police solving the case, or the academic achievements, the news that mankind originated in Africa is obviously more sensational.

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

There are not many academic achievements that can be brushed to this point by brushing the face.

Yang Rui was so excited that he could not help kicking up quickly.

"Be careful" Xie Meng was sitting behind, feeling the wind whistling in her ears, and exclaimed for a moment.

Wen Xiaoman chuckled twice and shouted, "No one in the alley, it's okay."

Yang Rui slowed down a little while pedaling, and asked, "Xiaoman, where did you see the news about the emergence of human beings in Africa? Which newspaper did you cut it from?"

"I've forgotten a bit. Otherwise, come to my house, I will look for it?" Wen Xiaoman was nervous and excited as if trying to lure idols to the home.

Yang Rui shook his head and said, "I'm afraid it won't work. I still have things to do today."

He actually didn't bother to go anymore.

Furthermore, it is a bit strange to go to other girls' homes.

Wen Xiaoman didn't regret the unsuccessful plan of the brainstorm, but continued to shrink into Yang Rui's arms, chatting with each sentence, hoping that the bus stop would be farther away.

It’s a pity that the bus system in Dajingcheng has always been densely packed. Not far from the entrance of the hutong, I saw green-skinned buses coming and going, and some buses were one-to-one with rubber hinged in the middle. A car can pull hundreds of people.

"Here." Yang Rui stretched out his foot and rubbed it on the ground, and the inertial bicycle brought him a little ahead before stopping.

Wen Xiaoman reluctantly jumped off his bicycle, suddenly remembered, and said: "Otherwise, I will take the briefing to your dormitory tomorrow."

"I'm not necessarily in the dormitory." Yang Rui said, with a somewhat disappointed expression that couldn't bear Wen Xiaoman. Furthermore, he really wanted to take a look at the newspaper clippings, and then said: "Let's make an appointment to my laboratory, Ion The Passage Laboratory is in Peking University. If you have time to come over someday, just call me..."

"No, I'll go tomorrow." Wen Xiaomanle was like a fan who got a photo with idols.

Her age, if she is a star chaser, is the dimly serious age she chased.

Regardless of his appearance or social performance, Yang Rui is much better than ordinary celebrities.

"Then tomorrow, before 6 pm, I will be in the laboratory, see when you can come over." Yang Rui said after a pause, and asked: "If you are in the middle school attached to the central bank, will you have class tomorrow?"

"It's okay, I can ask for leave." Wen Xiaoman still cares about such trivial things as class now.

Yang Rui hesitated and said, "It's better not to ask for leave as much as possible. Classes are also very important."

As a person in the 1980s, attending classes is indeed a very important thing, especially for art students. The level of education is the same as the background level, which means the difficulty of the future road. Students graduating from Beijing Film and Television, whether they want to do serious art or want to step into a feasting entertainment channel, have a door to go, but it is much harder for extras without academic background and background to become a star~ lightnovelpub.net~ You have to beware of cuckolding your wife and agent together.

In the same way, different people have different effects.

Like Wen Xiaoman's parents, if she is now standing in Yang Rui's position and asking her to study hard, most of what she will get is the hum of the rebellious period.

However, when Yang Rui said something similar, Wen Xiaoman was fully moved by concern, and said seriously: "I usually study seriously, tomorrow's course is okay, the afternoon is about art and body."

With that said, Wen Xiaoman bent a leg casually, pulled it with his hand, and pulled it to the back of his head.

Yang Rui was stunned, such a powerful big Lolita popped out of the second dimension.

"My physique class, the teacher allows me to move freely." When Wen Xiaoman was talking, the bus came, and she hurried into the bus, found an empty position by the window, and kept waving to Yang Rui. Goodbye.

Yang Rui got on the bike again, feeling better, and riding a little faster. When he arrived in the laboratory, he called Professor Dalbeko from abroad.
