Rebirth of the God-level Xueba

Xu Anqing stepped on a stone and saw Yang Rui was hearing a low plant spinning about twenty meters away, and a camera was hung around his neck at some unknown time. Liewen.com

Xie Gaoyi walked over with some amusement, and when he looked at Yang Rui, he was still thinking, he is still a young man.

It is not so easy to discover new species. A plant taxonomist, on average, only discovers three, four, or four or five new species in his lifetime.

And how many field surveys does a professional plant taxonomist have to do in a lifetime? There must be eight hundred if there is no one thousand.

It is not impossible to achieve something in the first field investigation, but the probability is too low.

Being a plant taxonomist is different from ordinary scholars. Plant taxonomists do not accumulate enough knowledge to find new species. They have to have face-to-face opportunities with new species.

Xie Gaoyi is also a man who has discovered a new species before. He knows how low the probability of this is. Moreover, he has heard too many similar problems:

"Teacher, I think I may have discovered a new species." This kind of child is the most stupid, but during the field investigation, the wild students are basically like this bird.

"Teacher, take a look at what species this is." This kind of child is relatively well-behaved, but the ending will not change in the slightest because of being well-behaved.

"Teacher, I found a strange plant." This is what Yang Rui said. However, the keen Professor Xie still heard the subtext in it. The problem is, the plant you think is strange, in my Professor Xie's eyes, It's totally normal.

Xie Gaoyi deliberately waited for Yang Rui to finish taking pictures and was ready to collect specimens before he stood over, looked down, and compared it with the species in his mind, saying: "It seems to be of the genus Bluethorn."

He has been to the Badaling forest area for countless times, and he is very familiar with the distribution of plants in the forest area. In fact, some research work is done on the distribution of plants in various forest areas.

For example, botanists know that there are more than one hundred species of the genus Bluethorn, and there are more than 10 species distributed in China, from northwest to northeast. Without such an understanding, Xie Gaoyi would not have dared to say that it belongs to the genus Bluethorn. It's as if you saw a tree like a coconut tree growing in the wild in Heilongjiang at minus 40 degrees, and it competed with a group of coniferous forests for living space. Do you dare to recognize it as a coconut tree? Let me start by saying that alien plants have a higher winning rate.

After confirming that it was a plant of the genus Ceruleus, Xie Gaoyi relaxed a little. This cannot be said to be a taxonomic group he is good at, but it is also a very familiar taxonomic group.

According to the decreasing law of the genus and species of the genus and species of the phylum, Xie Gaoyi began to make detailed judgments. At the same time, as a teaching task, Xie Gaoyi still had time to introduce to the students: "The species of the genus of the genus are all stout herbaceous plants. , are generally perennial, and some are biennial, and there are few annual ones. You can see that the upper part of its stem has branches and small fine hairs. These are the characteristics of the genus Cymbidium. After confirming these, let's look at the leaves. Generally smooth-edged"

Speaking of this, Xie Gaoyi stopped, because it was obvious that the edge of the herbaceous plant of the genus Echinococcus that Yang Rui found was not smooth.

Xie Gaoyi hesitated for a moment, but didn't bother with this point, and said: "There are also some with rough edges, which are relatively rare. Well, let's look at the tops of its stems and branches. In half, there are very small bristle-like bracts on the periphery. The package is usually one or two layers, this one has three layers."

Xie Gaoyi couldn't help raising his head, glanced at Yang Rui in surprise, then lowered his head to check again, this time, he didn't speak any more, but repeatedly turned the small herbaceous plants over and over again, like a wild dog digging through garbage.

After a while, Xie Gaoyi said: "As for the specific species of this plant of the genus Bluethorn, we have to go back and compare documents and specimens to be sure. This is what everyone will learn in the future."

Botanists are naturally experienced in plants,

However, it is impossible to know all the characteristics of each flower and plant.

Of course, the common species in the city or the local suburbs can be known at a glance, but that is because the plant species in the city and the suburbs are rare. After arriving in the forest area, it is relatively difficult to describe the characteristics of the common species. It's a test. Naturally, angiosperms like Chinese pine and black pine are not a problem at all.

However, if you want to go further, it is basically impossible.

There are currently more than 31,000 plant species in China. This number is a huge test for the brain capacity of botanists. It is difficult for normal humans to have such an IQ level. As for Scientists with genius-level brains—you are all genius-level high IQs, and you still want to be a plant taxonomist, is your head caught by a door?

"All in all, let's collect specimens first." Xie Gaoyi was serious, first took out his sketchbook, drew a plant shape, and drew a few strokes of the surrounding scenery, and taught Yang Rui to record the surrounding addresses.

Yang Rui did it very skillfully.

He searched in his mind for a long time just now, but he was just looking for the address.

For the discovery of a new species, you have to explain where it was found. Is it a natural new species on the bottom of the sea, or a miraculous corner like a mountain top that normal people would not climb, or in a basin, plateau, riverside, or saline-alkali land?

The specific location should not be missed, especially in places like the Badaling forest area, where students and teachers from field investigations are everywhere. If you find a suspected new species, you must record it clearly, maybe go back and look through the specimen cabinet. , you can see similar specimens collected by predecessors. In this way, you can save a lot of trouble by directly checking the conclusions of predecessors.

Moreover, there is another group of botanists who specialize in checking specimens to determine whether they are new species, or whether they are new distribution areas, etc. It is also a chain-like research system.

In front of Yang Rui, Xie Gaoyi naturally had to complete all the steps meticulously, and half taught Yang Rui to collect the specimens before he got up and stomped his feet, saying: "Everyone spread out and look for it, see if there are any other specimens nearby. For similar plants, generally speaking, the distribution of new species is relatively concentrated."

The students dispersed obediently, Xu Anqing came to Professor Xie with a strange expression, and said, "Professor Xie, it can't be a real new species."

He felt that Professor Xie might have made this decision to please Yang Rui. However, why did the dignified Peking University professor please Yang Rui, a student? The answer to this question, again, he was not willing to accept.

Not to mention Xu Anqing himself, even if his father came wearing the epaulettes of a general, the professor of Peking University would not need to please him.

Professor Xie didn't expect Xu Anqing to have such thoughts now. If he knew, he would probably be slapped flying. At this time, he said lightly: "I'm not sure about the condition of this plant. I want to take it back to have a look. Of course , it is very likely that the predecessors have already discovered it, but after all, there are some new features.”

"Didn't you also say that there are varieties with smooth and non-smooth edges?"

"There are no three-day bracts." Xie Gaoyi answered very definitely. The characteristics of a species of plant always have a range. After the range, it is worth exploring.

For example, a person has eight or nine fingers, and a man with eleven fingers calls himself a six-fingered Qin demon. The situation with twelve fingers cannot be said to be Xiang, but if someone has fifteen fingers , then of course there is reason to suspect that he is another kind of human being.

In fact, many new species that have been discovered in modern times can be called new mutant species. For example, the six-fingered piano demon was geographically isolated from normal humans, and after a long period of time, there was reproductive isolation again, so that it became a new species of six-fingered human. Humans are also possible.

Using fingers as an example is even wider. For a more extreme example, a normal man has three legs. Will there be a variation of four legs? —Do not write about natural variations! In the natural world, if you encounter a monkey with two younger siblings, it is worth investigating whether it is a new species for taxonomists.

Xu Anqing couldn't help but speak louder because of his strange dissatisfaction, and said, "Professor Xie, your standards are too broad. Yang Rui has never studied plant taxonomy."

Yang Rui answered honestly: "I really haven't learned much."

Professor Xie waved his hand and said, "To discover new species, it is not necessary to have studied plant taxonomy. Of course, it is generally necessary to have learned it before you have a better chance of discovering new species. A botanist will discover once or twice in his life. There are even those who grow plants that have not been discovered before, but amateurs also discover new species, and some people have better luck."

"Luck" Xu Anqing just wanted to find a tree, crash into it, and give herself to a lucky wolf.
