Xu Anqing stepped on a stone and stood on it, and he saw that 20 meters away, Yang Rui was smelling a low plant spinning, and he didn't know when, he hung a camera on his neck. Liewen

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

Finding new species is not so easy. A plant taxonomist will only find three or four or four or five new species in his lifetime.

And how many field surveys does a professional plant taxonomist do in his lifetime? There must be eight hundred without a thousand.

It's not impossible to get something in the first field survey, but the odds are too low.

Being a plant taxonomist is not the same as an ordinary scholar. Plant taxonomists do not have enough knowledge to find new species. They also have to have face-to-face opportunities with new species.

Xie Gaoyi is also a man who has discovered a new species. He knows how low this probability 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 stupidest, but when investigating in the field, the wild students are basically like this bird.

"Teacher, take a look at what species this is." This kind of child is more well-behaved, but the ending will not change 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 one ear. The problem is that the plant you find strange is in the eyes of Professor Xie. It's totally normal.

Xie Gaoyi deliberately waited for Yang Rui to take the photo and prepared to collect the specimens. Then he stood there, looked down, and compared with the species in his mind, and said: "It seems to belong to the genus Blue Acanthus."

He has been to the Badaling forest area how many times. He is very familiar with the distribution of plants in the forest area. In fact, some research work itself 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 Blue Acanthophyllum in the world, and there are more than 10 species distributed in China, from the northwest to the northeast. Without such an understanding, Xie Gaoyi would not dare to say that it belonged to the genus Blue. It's like you see a coconut tree growing in the wild in Heilongjiang at minus 4o degrees and competing with a group of coniferous forests for living space. Do you dare to recognize it as a coconut tree? Let me say that alien plants have a higher winning rate.

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

According to the descending law of the family, genera and species of the phylum, Xie Gaoyi began to make a careful judgment. At the same time, as a teaching task, Xie Gaoyi had time to introduce to the students: "The species of the genus Blue Acanthophyllum are all sturdy herbs. It is generally perennial, there are also biennials, and there are very few annual ones. Everyone looks at the upper part of its stalk, which has branches and small fine hairs. These are the characteristics of the genus Cyanaceae. After confirming these, let’s look at the leaves and leaves. Generally speaking, the edges are smooth"

Speaking of this, Xie Gaoyi stopped, because it was obvious that the edge of the blue thorn head herb that Yang Rui found was not smooth.

Xie Gaoyi hesitated for a moment, but did not entangle this point, and said: "There are also rough edges, which are relatively rare. Well, let's look at the top of its stems and branches. Half of them, there are very small bristles on the periphery. The package is usually one to 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. This time, he didn't speak any more, but repeatedly turned the small herb over and over again, like a wild dog rummaging through the trash.

After a while, Xie Gaoyi said, "As for the specific species of this plant of the genus Cynanchum, we have to go back and compare the literature and specimens to determine it. This is what everyone will learn in the future."

Botanists are naturally experienced in plants, but it is impossible to know all the characteristics of each flower.

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 cities and the suburbs are scarce. After the forest area, you can compare the characteristics of the common species. People are tested, naturally, angiosperms like Pinus tabulaeformis and black pine have no problem at all.

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

There are currently 31,000 species of plants in China. This number is a huge test for the brain capacity of botanists. It is difficult for normal humans to have this level of IQ. As for A scientist with a genius-level brain-you are a genius-level high IQ, and you are a plant taxonomist. Is your head caught in the door?

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

Yang Rui is extremely skilled.

He had been searching in his mind for a long time, but he was just looking for an address.

The emergence of new species must be explained. Is it a natural new species on the bottom of the sea, or a miraculous corner like mountain tops that normal people will not climb, or in basins, plateaus, rivers, or saline-alkali land?

The specific location must not be less, especially in places like Badaling Forest Area, where the students and teachers of the field investigation are everywhere, and you have discovered suspected new species. It must be recorded clearly. Maybe go back to the specimen cabinet. , You can see similar specimens collected by the predecessors, so that you can save a lot of trouble by directly checking the conclusions of the predecessors.

Moreover, there is a type of botanist who specializes in examining specimens, judging whether the specimen is a new species or a new distribution area, etc. It is similar to a chain-type research system.

In front of Yang Rui, Xie Gaoyi naturally completed all the steps meticulously and asked Yang Rui to collect the specimens before he got up and stomped, saying: "Everyone spread out to find out if there is anything nearby. For similar plants, in general, the distribution of new species is relatively concentrated."

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

He felt that Professor Xie might have made this kind of decision to please Yang Rui. However, why did the dignified Peking University professor please a student of Yang Rui? The answer to this question was again unwilling to accept.

Not to mention Xu Anqing himself, even if his father came with the epaulettes of the general rank, the professors of Peking University did not need to please.

Professor Xie didn't expect Xu Anqing to have this kind of thought now. If he knew it, he would probably slap it into the air. At this time, he said faintly: "I'm not sure about the condition of this plant. I have to take it back and take a look. It is very likely that the predecessors have already discovered it, but, after all, there are some new features~lightnovelpub.net~ You also said that there are varieties with smooth and non-smooth edges?"

"There are no three-day hair bracts." Xie Gaoyi replied very surely. The characteristics of plants in a genus always have a range, and beyond the range, it is worth exploring.

For example, a person has eight or nine fingers, and a man with eleven fingers calls himself the Six-Finger Qin Demon. In the case of twelve fingers, it cannot be said to be Xiang, but if someone has fifteen fingers , Of course there are reasons to suspect that he is another kind of human being.

In fact, many new species in modern times can be called new mutant species. For example, the six-fingered piano demon was geographically isolated from normal humans. After a long time, there was reproductive isolation, so that it became a new species of six-finger People are also possible.

The example of using fingers to make the scope is broader and more extreme. Normal men have three legs. Will the variation with four legs appear? ——Don’t write about natural mutation! Falling in nature, if you encounter two monkeys with younger brothers, for taxonomists, it is completely worth investigating whether it is a new species.

Because of strange dissatisfaction, Xu Anqing couldn't help loudly speaking, "Professor Xie, your standards are too broad, right? 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, you don’t have to learn plant taxonomy. Of course, you usually have to learn before you have the chance to discover new species. A botanist can discover one or two in a lifetime. There are plants that have not even seen new species, but amateurs have found new species less than that, and some people have better luck."

"Luck" Xu Anqing just wanted to find a tree, smashed it to death on it, and gave himself to a lucky wolf.
