"Really, I just saw it two days ago, so I couldn't remember it when I used it." Wen Xiaoman patted his forehead, very annoyed.

"Don't move around, the car is about to fall off." Yang Rui held the handlebars tightly and rode the bicycle of three passengers in one breath. It was not that easy to ride.

Moreover, Wen Xiaoman was hiking into his arms, while Xie Lei from behind hugged him tightly, and driving the vehicle seemed to be more difficult.

Wen Xiaoman heard Yang Rui's words and felt a little obedient, but after a moment of recalling, he raised his neck and squirted into Yang Rui's ears, and said, "I remember it, it's about the origin of human beings. Dad said it is a very important research topic, right?"

Yang Rui was a little dizzy when he was impacted by the girl's unique sweet fragrance. He reacted in an instant and said in surprise: "Humans walked out of Africa? Have they made it out now?"

"Huh? You know." Wen Xiaoman raised his chest in surprise, but his lips almost rubbed against Yang Rui's ears, perhaps rubbing against the fluff on his ears, which made people feel itchy.

Yang Rui felt aroused in his heart, and quickly pretended to be riding a bicycle hard, and said seriously: "It is indeed a serious topic for humans to go out of Africa, I have heard of it."

The issue of the origin of human beings is more than a serious topic, it is an important topic, especially for the biology community in the 1980s, which attracted more attention than HIV.

This is mainly because the topic of human origin has extremely heavy social attributes, and, without doubt, 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.

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

And this answer, perhaps not likeable in the 1980s - because DNA tests performed through PCR showed that humans originated in Africa.

Compared with the various guesses before this, DNA testing using PCR is more authoritative and more unexpected.

For pretentious whites, for yellows who are proud of history, the answer they prefer, or the answer they prefer to accept is the theory of multi-original origin of human beings, that is, human beings were born in multiple places on the earth in a similar time. In the 21st century, some people still insist on this theory.

However, the mainstream argument, since the invention of PCR, has been "human originated in Africa".

This answer is also a concentrated debut of PCR around the world, and can be said to be a successful interdisciplinary practice of PCR.

Compared with police investigations or academic achievements, the news that humans originated in Africa is obviously more sensational.

It can be imagined that for a long time, the news will become the headlines of major news media, not only the headlines of technologically developed countries like the United States and the United Kingdom, but also the headlines of underdeveloped countries like China and Kenya.

There are not many academic achievements that can achieve this level of face scanning.

Yang Rui was excited and couldn't help but kicking his feet quickly.

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

Wen Xiaoman giggled twice and shouted, "There is no one in the alley, it's okay."

Yang Rui slowed down a little while pedaling and asked, "Xiaoman, where did you see news about humans walking in Africa? Which newspaper did you cut it out?"

"I've forgotten a little. Otherwise, I'll look for it at my house?" Wen Xiaoman was nervous and excited as if she was trying to lure her idol to the fans at home.

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

He was actually too lazy to go again.

Furthermore, it is also a bit strange to go to other girls’ houses.

Wen Xiaoman was not sorry that the inspirational plan did not succeed, but just continued to hide in Yang Rui's warm arms, and had a chat with every word, hoping that the bus stop would be a little further away.

Unfortunately, the bus system in Dajing City has always been dense and unnecessary. Not far from the entrance of the alley, I saw green buses coming and going. Some buses were towed one by one, with rubber in the middle, and a car could pull hundreds of people.

"It's here." Yang Rui stretched out his feet and rubbed it on the ground. The bicycle with full inertia took him in front of him before stopping.

Wen Xiaoman jumped off the bicycle reluctantly, and suddenly remembered it and said, "Otherwise, I'll go to your dormitory with a briefing tomorrow."

"I may not be in the dormitory." Yang Rui said, feeling a little disappointed with Wen Xiaoman's expression. Besides, he really wanted to read the newspaper clippings, so he said: "Let's do it, let's make an appointment to my laboratory, the ion channel laboratory, right at Peking University. If you have time to come one day, call me..."

"No, I'll go tomorrow." Wen Xiaomanle felt as if he had a fan of the idol group photo.

Her age, if she was chasing stars, she was the serious age of chasing the sky and the earth.

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

"Then tomorrow, before 6 pm, I'll be in the laboratory to see when you can come." Yang Rui paused and asked, "If you are at Yangyin Affiliated Middle School, will you have class tomorrow?"

"It's okay, I can ask for leave." Wen Xiaoman doesn't care about small things like class now.

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

As a 1980s, attending classes is indeed an extremely important thing, especially for art students, the same academic qualifications as backgrounds, which means the difficulty of the future path. Students who graduate from Beijing Film Academy or Yangyin, whether they want to do serious art or enter the entertainment channel with bright and bright lights, have a door to go, while extras without education and backgrounds are much more difficult to become stars, and they have to be careful of their wives and agents cuckolding together.

The same thing, different people say different effects.

Like Wen Xiaoman's parents, if they are now standing in Yang Rui's position and ask her to study hard, they will probably get a rebellious humming.

However, when Yang Rui said similar words, Wen Xiaoman was moved by the care and said seriously: "I usually study hard. Tomorrow's courses do not matter, but the afternoon is just art and body."

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

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

"In my body class, the teacher lets me move freely." Wen Xiaoman was talking when the bus arrived. She quickly walked onto the bus, found an empty space by the window and stood there, and kept waved her hands to Yang Rui to say goodbye.
