Xu Anqing listened more seriously. network

After walking a little longer, he rushed to Professor Xie Gaoyi and asked softly: "If you want to discover a new species, what exactly needs to be done?"

Xie Gaoyi is obviously not the first time he has met such a student, but he is willing to explain to him that the students around are listening with their ears upright, and they raise their voices. He laughed and said, "The discovery of a new species is not a simple matter. Everyone knows that in the eighteenth and nineteenth centuries, it was the century of naturalists. It was a golden age. There were too many new species. The origin of species was written at that time. At that time, there was even no existence. People set foot on the island, as long as you go up, you can do a good job of naming it for a few years."

Speaking of this, Xie Gaoyi himself was fascinated for a few seconds before continuing: "It's not going to work now. Now, like the Badaling forest area where we are currently, it has been shaved like a comb. I don't know how many times. It’s not impossible that new species will appear, and the probability is very low."

Xie Gaoyi really didn't dare to say the whole thing. The Badaling Forest District is indeed the main education area for the botany departments of several universities in Beijing. There are countless experts and professors passing by and inspecting them, but what about it? Historically, stories of new species have appeared in the school teaching area, but they are endless. Some universities have even experienced this situation two or three times. The complexity of plants determines their characteristics.

Compared with plant majors, Xie Gaoyi, who grew up listening to natural history stories, felt less empathetic among the students. They just quietly heard Xie Gaoyi and waited for him to talk about the part of playing meat.

Xie Gaoyi was immersed again for a while, and then said: "If students are interested in plant taxonomy, studying the classification of plants, discovering new plant species, and understanding the knowledge of new plant species, it is called plant taxonomy. If students stop there. If so, the first thing to do is to observe and analyze plants, and it is best to find the direction of a taxa. Do you know what a natural taxa is?"

The classmates shuffled one after another, and some people meditated on the family, genera, and species, but they did not find the concept of group.

Xie Gaoyi smiled and said: "A taxa is a taxonomic unit. We are now talking about a natural taxa. To see which taxa a species belongs to, is to see whether it has the same evolutionary source as the species of the same group."

The students nodded seemingly.

Xie Gaoyi came to class today, so he said again: "Let me give you an example. Ferns are a group, they have the same common features, for example, sporophytes, sporangia, mature sporangia, and short-lived The existing gametophytes, after determining these, can basically determine whether a new plant belongs to the fern or non-fern plant. However, it is not easy to do this."

Xie Gaoyi took a deep breath and said, "I have done research for more than 20 years, and now I dare to say that there are only a few taxa that I am familiar with. Let’s put it this way, if you start from today, you will know a few of them every day. In a few years, you will become familiar with one or two taxa, and then conduct field surveys based on different taxa, and you will be able to focus on them."

Xu Anqing and the students around him nodded slightly.

"This is an arduous process." Xie Gaoyi sighed and said: "Standing here today, I have to pour some cold water on the students. Now, after the identification of the species that everyone finds, 90% of the results are all. It’s just what’s written in the book."

The students couldn't help laughing.

Xie Gaoyi also laughed and said, "You are still laughing now. When you encounter something like this, you won’t be able to laugh anymore. Think about it, if you finally discover a new species, you must have never seen it before. , Then you have to make a good record, search and search, saying that you must not borrow the specimens of our school, compare the plants of the same group or the adjacent group, and finally found that it is all in vain, qi is not angry? Are you annoyed?"

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

Xu Anqing's heart trembled even more, and said: "This way, do you have to remember the shape of the plant?"

"Yes. Why, feel difficult?" Next

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

"It's never harder to learn than English." Xie Gaoyi laughed and said again: "Now the technology is getting better, just say which taxonomy is identified. We used to do taxonomy, it was too busy. I have worked more. Now, I want to thank our classmate Yang Ruiyang."

The whole class was inexplicably stunned for two seconds, then suddenly looked back 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 a bit. Could God ****** tell me what happened?

Xie Gaoyi didn't make everyone wait too long, and quickly solved the mystery, saying: "We can now identify taxa, we can use the pcR method of classmate Yang Ruiming. Simply put, don't we want to test whether the species are homologous? DNA knows how to measure it. You can ask Yang Rui for advice after class. In other words, this is the direction and trend of our future biology exhibition. The precise quantification depends on Yang Rui’s pioneering understanding in this area. It makes sense."

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

To say that he is studying abusive, Yang Rui’s news and news have never been interrupted. Everyone knows that Yang Rui is extremely powerful. However, Professor Xie’s evaluation is still staggering.

Today's students are no better than later, they are familiar with all kinds of politicized test language, and I was shocked to hear Professor Xie say that the trend of biology depends on Yang Rui's pioneering understanding.

This is mainly because Xie Gaoyi is not a teacher of biological acupuncture industry, and Yang Rui's teacher of this major, out of various considerations, will not raise Yang Rui too high. Xie Gaoyi doesn't matter. In fact, he still lowered some evaluations, or that he hasn't realized the greater value of pcR. Otherwise, the noble-level technology will only get a pioneering evaluation.

Yang Rui also accepted Xie Gaoyi's evaluation without shame, and pcR can stand up to this evaluation. In terms of personal contribution to the world, the first version of the pcR instrument was made in advance, which might have added modern science.

This alone is common, and there may not be much difference in three or five years. After ten years, the number of patients who can be better treated as a result will not be described by tens of thousands, in millions. All belong to Qianci.

Yang Rui's high-spirited face and smile were irritating, Xu Anqing's face was red, but his body was cold, as if the military coat hadn't worked at all.

Xu Anqing thought of his father.

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

In this comparison, Xu Anqing felt that Wuling was even more depressed.

"The main forest area is ahead." Professor Xie led the team and continued to move forward. The road under his feet was a little slippery and rugged, which made people have to converge.

Professor Xie did not lead the team to 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’s a plant major who has conducted field surveys 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. For the first time, perhaps the only biology student who has conducted field surveys. That said, there is no need to go deep into the dense forest.

Walking around the forest area is already difficult for the factory.

The dirt roads in the forest are criss-crossed and seem to be even more intermittent from a distance. They are either destroyed by overgrown weeds or covered by white snow. The uneven roads consume more energy, even if they are physically exhausted. The student walked out of breath.

The inevitable uphill and downhill slopes are even more dangerous. Even if there is no moss, the rocks in the forest area are extremely slippery with dew and leopards. In some sections of the road, the students fell one by one, and the back watched the front movements awkwardly. , But when it's his turn, he just lay down awkwardly.

When Professor Xie talked about the names of plants, the students could only look up weakly. There was no one taking notes. The act of just taking notes and putting them on would be tiring to call them out.

Yang Rui also started to feel physically exhausted, and only felt that the bag on his body was getting heavier. However, his spirit was very good, because he slowly began to align the road he walked with the map in his mind. .

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

Professor Xie didn't have any comments, so he adjusted his direction according to Yang Rui's advice.

Walk a bit~lightnovelpub.net~ Yang Rui said again: "Professor Xie, let's climb the hill over there? Be warmer."

"You lead the way." Professor Xie didn't know what Yang Rui meant, but face was to be given.

After doing this three times, Xu Anqing felt uncomfortable.

"I was praised for a few words, so I pretended to be a wolf with a big tail." The classmates said, trying to figure out Xu Anqing's mood, and commented.

University students have a variety of relationships. Zuo Li said that Anqing’s upper bunk always likes to run with him. It also forms a wonderful dogleg symbiosis.

After two years of getting along, Xu Anqing is like the queen mother who can't do without her son, and can't do without Zuo Liyan.

Zuo Liyan's words were in line with Xu Anqing's mind. He laughed twice, took a breath of the cold forest air, smiled, and said, "Let his tribe have the ability to discover a new species."

"He doesn't recognize the new species. I'm angry when I see him like that. I can't listen to the wave of the old arrow." Zuo Liyan himself also has a lot of dissatisfaction.

"If he loves to command, let him command. People might just watch to put a big satellite. In Badaling, Beijing, there is a new species that no one has seen before." Xu Anqing said and laughed.

Zuo Liyan was also coughing with a smile.

A classmate around the two heard it. Although they didn't agree with them, they still found it a bit funny.

Indeed, there are green and white woods on the left and right, and it is even more exhausting to go over a hill deliberately.

Just when the team started to laugh, the team was walking slowly and slowly, and Professor Xie's shout came from the front: "Yang Rui, don't go far."

"I think this plant is a bit weird. I will take a specimen, Professor Xie, can you help me take a look?" Yang Rui's voice came from the empty woods, arousing the curiosity of the students.
