Over the next two hours, the students found four more of the same plants within a few hundred meters of the surrounding area. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

As a result, Professor Xie's attitude has become more positive and serious.

Obviously, this means that what Yang Rui found is not some kind of special mutation, although whether it is a new species needs to be studied, but it is a species is undoubted.

In fact, new species are often new species that form new populations, and the so-called evolutionary stillness is a complete joke in the professional academic field.

Species, including humans, are evolving all the time.

However, in order to become a new species, it takes more than just mutation. For taxonomists, the reality is that species are not being discovered at the rate of species disappearing, and species on Earth are exhausted in order to adapt to a rapidly changing planet.

Xu Anqing was also exhausted.

He also wandered around the field for two hours, and he even saw a plant of the genus Bluethorn in the distance, but this only made him more and more irritable.

He really wanted to ask Yang Rui, why do you think this plant is strange?

For Xu Anqing, who has lived in a big southern city since childhood, most of the plants in the Badaling forest area are strange. And he can't point to every plant to ask Professor Xie, at least, he can't point to a plant dozens of meters away to ask Professor Xie.

However, if Xu Anqing was killed, he would not ask Yang Rui.

As a result, the more doubts became, the lower Xu Anqing's mood became.

Professor Xie sees the changes in Xu Anqing.

After a while, when the specimen collection was over and the team was ready to return, Professor Xie Gaoyi took the initiative to come to Xu Anqing's side and said, "You know, being a botanist and discovering new species is about temperament. ”

"Well, what do you mean by the temperament of a botanist?" Xu Anqing was a little confused for a while.

Professor Xie looked at the distant mountains and said: "Some botanists are like glue on their bodies, no matter how they do field investigations, they can find new species, and some botanists do not necessarily have this temperament, but it does not mean that there is no way out." ”

Xu Anqing naturally looked at Professor Xie.

"For example, if you say a citizen who doesn't have a complete botanical education, and he discovers a new species, or discovers a suspected new species, what should he do?" Professor Xie advised.

Xu Anqing replied without much thought: "It should be to find a professional and authoritative agency to do the appraisal." ”

Professor Xie nodded and said, "That's right. But in fact, it is basically impossible for people in the private sector to find professional institutions to do appraisals. ”

Xu Anqing said in surprise: "Why?"

"Because we don't have enough people to identify these species. Xie Gaoyi said calmly: "Do you know how many standards for suspected new species exist in our Peking University alone?"

Xu Anqing shook his head blankly.

Xie Gaoyi said: "I don't know either, because there are too many." ”

Xu Anqing was dumbfounded.

"What I mean by this is that the discovery of new species is not the only way out for botanists, nor is it the most important place, but the botanists we need most are capable of identifying and analyzing new plants and new specimens. Xie Gaoyi said this, paused, and said: "If you have enough identification and analysis ability, you don't need to go out to find new plants at all, you just stay in the laboratory and sort out the past specimens." ”

Xu Anqing understood at this moment, and said: "What you mean is that there are two kinds of botanists, one is to do field surveys and discover new species, and the other is to analyze and identify new species. ”

Xie Gaoyi was stunned for a moment and said, "Is this what I mean?"

"Yes. ”

"You're mistaken. Xie Gaoyi immediately denied it, saying: "Botanists are all about analyzing and identifying new species, but some botanists are always unlucky when they do field surveys and can't find new species, so it is also a very valuable job to check the specimens in the laboratory." ”

Xu Anqing couldn't wait to bury his head in the soil, and then asked Professor Xie, who was buried deeper: Didn't you call me an old scholar?

In Professor Xie's eyes, the old scholar may be a good choice, but for a young and frivolous college student, it is no different from dying.

At this time, Professor Xie looked at Xu Anqing, who was deep in thought, and felt that he had comforted the child perfectly, nodded, and said, "If you want to learn botany knowledge in the future, you can come to me at any time." ”

After that, Professor Xie continued his teaching task, explaining the plants he saw to the students along the way.

But unlike when they came, the students, who had just experienced a suspected discovery of a new species, were not interested in familiar plants at all, and their eyes kept wandering around the field.

Everyone understands that the plants on both sides of the mountain road are often seen, and in the surrounding fields, the chance of plants being observed is greatly reduced.

It didn't take long for a classmate to shout: "Professor Xie, come and see this plant." ”

Professor Xie didn't want to favor one over the other, so he had to step over the slippery ground, through a barren meadow, and lean over to observe.

"Bush clover. Professor Xie bent down and looked at it for five seconds, then straightened up.

The students still looked at Professor Xie with blank eyes.

"Leguminaceae, Bush clover. Professor Xie sighed and said, "In the Badaling area, this is a common shrub. ”

"Wouldn't it be a new species of the genus Bush Branch?" the student was a little unwilling.

"Look at the branches, look at the petioles, look at the short thorns, they are all normal forms. Professor Xie paused for a moment and said, "When we talk about new species, they generally have relatively different appearances, and then we have to judge whether these appearances determine the taxa to which the species belongs. Well, everyone should still observe more and accumulate more. ”

"Yang Rui didn't find out. At some point, Geng Jian came to Professor Xie and muttered quietly.

Professor Xie sighed and said, "Discovering new species requires luck and the temperament of a botanist. ”

"Professor Xie, then you can take a look at this. Geng Jian didn't care what he said, and directly found a different plant in front of him.

Professor Xie turned his head and said, "Euonymus." ”

"For Mao?" Geng Jian thought for a moment, his face changed slightly, and said, "Professor Xie, I think this plant is different from the plants we have seen along the way......

"Euonymus!"

"It's not...... Just take a look at ......."

"It's holly euonymus, a shrub. Professor Xie said, adding: "This is an ornamental plant introduced from Japan, and many of them are cultivated in China. ”

Geng Jian was stunned for a moment, speechless.

"I think so, it's getting late, we have to hurry back, each student is limited to one chance to ask questions, you can ask questions, you can not ask questions, in addition, you are not allowed to leave the team for 50 meters, otherwise, I will record the list and hand it over to your counselors." Professor Xie quickly came up with a solution that barely eased the situation.

At this moment, even students who don't have the nature of asking questions can't help it.

Who doesn't want to discover a plant by themselves, go out and brag in the future, to say the least, I have also made contributions to the world's scientific research, sweated, endured hardships, and had the peak of life.

As for Professor Xie, he inevitably fell into the sea of people's war.

He found that he didn't have to explain the plants along the way, almost all the plants he passed by were turned over by the students, and almost everyone was hanging around 50 meters away, as if the farther away from the dirt road, the closer to success.

Bai Ling couldn't help but drag Yang Rui to discover a new species.

The two broke away from the group and loomed in the woods.
