Rebirth of the God-level Xueba

Xu Anqing listened more seriously. network

After walking a little further, he arrived at Professor Xie Gaoyi, and asked softly, "If you want to discover a new species, what exactly do you need to do?"

Obviously, this is not the first time Xie Gaoyi has encountered such a student, so he is willing to explain it to him. Seeing that the students around him are listening with pricked ears, he simply raised his voice and said with a smile: "Discovering a new species is not a simple task. As you know, the 18th and 19th centuries were the century of naturalists, the golden age, and there were too many new species. The Origin of Species was also written at that time. At that time, there were even countless It is a small island where people set foot, as long as you walk on it, you can do the naming work for several years."

Speaking of this, Xie Gaoyi himself was fascinated for a few seconds, and then continued: "It can't do it now. Now, like the Badaling forest area where we are currently, it seems to be scratched by a comb. I don't know how many times, It is not impossible for new species to appear, the probability is very low."

Xie Gaoyi really didn't dare to talk too much, the Badaling forest area is indeed the main education area of ​​the botany departments of several universities in Beijing, and countless experts and professors passed by and inspected, but so what? Historically, there have been endless stories of new species being discovered in school teaching areas, and some universities have even seen this happen two or three times. The complexity of plants determines their characteristics.

Compared with the botanical major, Xie Gaoyi, who grew up listening to natural history stories, the students have less empathy, just quietly smelling Xie Gaoyi, waiting for him to talk about the meat part.

Xie Gaoyi immersed himself for a while again, and then said: "Students, if you are interested in plant taxonomy, study the classification of plants, discover new plant species, and understand the knowledge of new plant species, it is called plant taxonomy. If so, the first thing to do is to observe the plants, analyze the plants, and, it is best to find the direction of a taxon. Do you know what a natural taxon is?"

The students flocked one after another, and some people meditated on the genera and species of the family of the Jiemen Gangke, but they did not find out the concept of the group.

Xie Gaoyi smiled and said: "Groups are taxon units. When we talk about natural groups now, to see which group a species belongs to is to see whether it has the same evolutionary source as the species of the same group."

The students seemed to understand but nodded.

Xie Gaoyi came to class today, so he said again: "Let me give you an example. Ferns are a group, and they have the same commonality, for example, sporophytes, sporophytes, mature sporangia, and short-lived Existing gametophytes, if these are determined, it can be basically determined whether a new plant is in the group of ferns or in the group of non-ferns. However, it is not easy to do this.”

Xie Gaoyi took a deep breath and said: "I have done more than 20 years of research, and now I dare to say that I am familiar with the taxa, there are only a few. Let's put it this way, if everyone starts today and knows a few taxa every day. species, after a few years, get familiar with one or two taxa, and then conduct field surveys based on different taxa, then you will be able to target the target.”

Xu Anqing and the students around her nodded slightly.

"This is a difficult process." Xie Gaoyi said with emotion, "Standing here today, I have to pour a little cold water on the students. Now, the species you find, after identification, 99% of the results are oh, it turns out that this It’s what’s written in the book.”

The students couldn't help laughing.

Xie Gaoyi also laughed, and said: "You can still laugh now, but you won't be able to laugh when you encounter this kind of thing. Think about it, if you finally found a new species, you must have never seen it before. , then we have to make good records, search and search, maybe even borrow the specimens we learned from, compare the plants of the same group or adjacent groups, and finally find that it is all for nothing, are you angry? Are you annoyed?"

The students imitated the route Xie Gaoyi said in their hearts, and all of them were concerned.

Xu Anqing's heart trembled twice, and said: "This way,

Do you have to memorize the shape of plants? "

"That's right. Why, do you find it difficult?"

Xu Anqing nodded obediently, and said, "I don't think it's easy to remember."

"It will never be more difficult to learn than English." Xie Gaoyi laughed twice, and said: "The technology is getting better now, just to identify which taxa it is, we used to do taxonomy, it was too busy I have worked a lot, now, I would like to thank our classmate Yang Ruiyang."

The whole class was inexplicably stunned for two seconds, then suddenly turned to look at Yang Rui.

Although Yang Rui didn't know why, he still stood still with a smile and kept smiling.

Xu Anqing couldn't laugh anymore, goddamn can you tell me what happened?

Xie Gaoyi didn't keep everyone waiting too long, and quickly revealed the answer, saying: "We can now identify the taxa through the pcR method invented by Yang Rui. Simply put, aren't we going to test whether the species are homologous? You can ask Yang Rui for advice on how to measure the specifics. Needless to say, this is the direction and trend of our biology's future development. Accurate quantification depends on Yang Rui's pioneering invention in this area. It makes sense."

Xie Gaoyi lifted Yang Rui up very high, and the students who listened were stunned.

Speaking of being a student, Yang Rui's news and news have never been interrupted. Everyone knows that Yang Rui is extremely powerful, but Professor Xie's evaluation is still staggering.

Today's students are not as familiar as they are in the future, and they are familiar with all kinds of political examination terms. It is shocking to hear Professor Xie say that the trend of biology depends on Yang Rui's pioneering invention.

This is mainly because Xie Gaoyi is not a teacher of biological acupoints, and Yang Rui's teacher of this major will not raise Yang Rui too high for various considerations. Xie Gaoyi didn't care. In fact, he still lowered some evaluations. In other words, he hadn't realized the greater value of pcR. Otherwise, how could such a dignified Nobel Prize-level technology only get a pioneering evaluation.

Yang Rui also accepted Xie Gaoyi's evaluation without shame, and pcR deserved this evaluation. As far as personal contribution to the world is concerned, making the first version of the pcR instrument in advance may not be an addition to modern science.

This item alone is common, and there may not be much difference in three to five years. After ten years, the patients who can get better treatment because of this will not be described by tens of thousands. All are humble words.

Yang Rui's high-spirited and smiling face made Xu Anqing's face flushed red, but his body was cold, as if the military coat didn't help at all.

Xu Anqing thought of her father.

He was thinking that even his own father probably couldn't get a better evaluation from someone like Professor Xie.

Compared with this, Xu Anqing felt even more dejected.

"The main forest area is ahead." Professor Xie led the team and continued to move forward. The road under their feet was slightly slippery and rough, which made people have to restrain their minds.

Professor Xie did not lead the team into the main forest area. Although it is the teaching forest area where the capital is located, the forest area is a forest area after all, and there are always countless dangers. If it is a botanical student who has conducted field investigations many times, or a researcher at a research institute who has done plant research for many years, he may lead the team to go deeper. Said, there is no need to go deep into the jungle.

Walking around the forest area is already very difficult.

The dirt roads in the forest area are criss-crossed, and they look even more discontinuous from a distance. They are either destroyed by overgrown weeds or covered by white snow. The students also walked out of breath.

The inevitable uphill and downhill are even more dangerous. Even if there is no moss on the stones in the forest area, they are extremely slippery due to the dew and the wetness of leopards. In some sections, the students fell one by one, and those behind looked at the front and moved clumsily. , but when it was his turn, he also lay down awkwardly.

When Professor Xie mentioned the names of plants, the students could only look up feebly. There was no one taking notes. Just the act of taking notes and putting them down can make people scream out tiredly.

Yang Rui also began to feel physically exhausted, only to feel that the bag on his body was getting heavier and heavier, but his spirit was very good, because he began to slowly match the road he had traveled with the map in his mind .

"Professor Xie, let's go south. There will be less snow in the south." Yang Rui began to give suggestions at the fork in the road.

Professor Xie had no opinion, so he adjusted the direction according to Yang Rui's opinion.

After walking a while, Yang Rui said again: "Professor Xie, let's climb the hill over there? It's warmer."

"You lead the way." Professor Xie didn't know what Yang Rui meant, but he had to give face.

After doing this three times, Xu Anqing felt uncomfortable.

"After being praised a few times, I pretended to be a wolf with a big tail." My classmate Tong Yang made a statement, trying to figure out Xu Anqing's mood, and commented.

University classmates have various relationships. Zuo Liyan is the upper berth of Anqing, and always likes to run with him, forming a wonderful dog-leg symbiotic relationship.

After two years of getting along, Xu Anqing couldn't do without Zuo Liyan just like the empress dowager couldn't do without her son.

What Zuo Liyan said was just in line with Xu Anqing's thoughts. He laughed twice, took a breath of the cold forest air, smiled, and said, "Let him branch out, if he has the ability to discover a new species."

"He can't even recognize a new species. Seeing him like that makes me angry. I can't listen to Lao Ya if he walks around like that." Zuo Liyan himself also has a lot of dissatisfaction.

"If he likes to command, let him command. Maybe they are planning to launch a large satellite. In Badaling, Beijing, a new species has never been seen before." Xu Anqing said and laughed.

Zuo Liyan also laughed and coughed.

A classmate around the two heard it, and although they would not agree with it, they still found it a little funny.

Indeed, there are green and white forests on the left and right. Wherever you go, you are not walking, and it is even more exhausting to turn over a hill.

Just when laughter started at the end of the line, the front of the line was getting slower and slower, and Professor Xie's shout came from the front: "Yang Rui, don't go far."

"I think this plant is a bit strange. I'll take a specimen. Professor Xie, can you take a look?" Yang Rui's voice came from the open forest, arousing the curiosity of the students.
