Chapter 1112

Xu anqing stepped on a stone to stand up, and he saw that more than 20 meters away, Yang Rui was circling around a low plant, and a camera was hanging around his neck at some time.

Xie Gaoyi is a little funny to walk past, when he looks at Yang Rui, he still thinks that he is really a young man.

It's not so easy to find new species. A plant taxonomist can find three, four or five new species in his life.

How many field surveys does a professional taxonomist have to do in his life? If you don't have 1000, you have to have 800.

Professor Xie didn't expect Xu Anqing to have this kind of thought now. If he knew, he would slap him in the face. At this time, he said faintly: "I'm not sure about this plant. I want to take it back and have a look. Of course, it is very likely that the predecessors have discovered it, but after all, there are some new features. "

"Don't you also say that there are varieties with smooth edges or not?"

"Three ring bracts without setae." Xie Gaoyi very sure answer, a species of plant characteristics always have a range, beyond the range, it is worth exploring.

For example, a man has eight or nine fingers, and a man with eleven fingers has six fingers. The situation of twelve fingers can't be said to be unusual. However, if a man has fifteen fingers, there is certainly reason to suspect that he is a human of other kinds.

In fact, many new species discovered in modern times can be called new variant species. For example, six fingered harp demons are geographically isolated from normal human beings. After a long period of time, there is reproductive isolation, so that it is possible to become a new six fingered human.

If you use your fingers as an example of the range, it's a broader, more extreme example. A normal man has three legs. Will there be a mutation with four legs—— Don't underestimate natural variation! In the natural world, if we meet two little brothers of monkey, it is worth investigating whether it is a new species for taxonomists.

Xu Anqing, however, could not help shouting out a little because of his strange dissatisfaction and said, "Professor Xie, your standard is too broad. Yang Rui has never studied plant taxonomy."

Yang Rui honest answer: "I really did not learn much."

Professor Xie waved his hand and said, "it's not necessary to have studied plant taxonomy to discover new species. Of course, it's generally necessary to learn before you have a chance to discover new species. A botanist can discover one or two plants in his life, or even find no new species. However, there are also amateurs who discover new species. In a word, some people are lucky. "

"Luck..." Xu anqing just wanted to find a tree, hit and die on it, and gave himself to a lucky wolf.
