Every Day One Step Closer To the Manifestation Chapter 211

Xiaojia scratched his head, "Declare territory... usually through physical signals or chemical signals. Physical signals are scratches, bite marks, etc., and chemical signals are used to emit odor information in various ways. A warning sign is about the same."

Isn't that what it takes to declare territory?

It doesn't matter whether the physical signal or the chemical signal, if the markings are useless, they will fight.

Xiaojia wondered why Feng Yi was interested in these?

After saying a few words, Xiao Jia observed Feng Yi's reaction.

I can't tell if Feng Yi agrees with that expression, but he must have heard it, and he doesn't know what he is thinking.

After waiting for a while, Feng Yi asked Xiao Jia to rest. He continued to watch the documentary by himself. After taking a shower, he lay on the bed, thinking about the method of declaring the territory. .

Instinct told him that relevant information was recorded in his ancestral DNA, but he had to try it himself to know how to operate it.

I don't know if I thought too much before going to bed. At night, Feng Yi had a lot of messy dreams, but he couldn't remember when he woke up.

Before going out in the morning, Feng Yi asked Xiao Jia to prepare, and he had something to do when he sailed on a yacht in the evening.

Xiaojia didn't ask much, but answered excitedly. It is enough for him to execute, what the boss tells him to do.

Although I don't know what Feng Yi is going to do, it doesn't matter, he finally has a role to play!

Where to go to sea, what time period, and which direction, he already knew what to do, and he would check it out later.

As for fishing...

What fish to catch!

Is fishing fun to go out to sea with the boss?

It would be even better if the boss could bring him with him!

Xiaojia rushed out the door.

Feng Yi, on the other hand, went out to sea with the investigation team after breakfast, just like the previous days, but he returned at noon after a half-day mission today. The bosses are going to hold several important meetings. This time, non-core members such as Feng Yi do not need to attend.

There was nothing else, and there were many doubts in his heart. Feng Yi couldn't stay in the dormitory any longer, so he took a nap in the dormitory and was ready to go out.

Changed out of work clothes, wearing a simple style sweater, sunglasses hanging neckline.

Since the first time he went to the street for food and was recognized, when Feng Yi went out to hang out again, he would not wear work clothes.

At the north gate of the dormitory area, Feng Yi saw Professor Ding walking in from the outside.

The **** dog who was in charge of guarding the north gate probably got acquainted with Professor Ding, and moved his tail closer.

While touching the dog, Professor Ding chatted with the old Liu in the guard booth and raised his hand to say hello when he saw Feng Yi.

Feng Yi walked over and asked him, "Is the meeting over so soon?"

Professor Ding waved his hand, "I have already given them the data and analysis report. Anyway, I don't follow the investigation team here all the time. We still have our own tasks, and we will let them decide to go here."

Then he asked Feng Yi, "How did you read the courseware yesterday? Do you have any questions?"

Feng Yi, who thought about "declaring territory" for a whole night and didn't read the courseware: "...Yes."

Professor Ding was interested, "Tell me, I just have time now."

Feng Yi: "It's not in the courseware, I thought of it when I read other materials. Can different species really communicate with each other through chemical substances?"

Professor Ding said, "Of course!"

Without the slightest hesitation.

Professor Ding: "Each trophic level of the ecosystem food chain has formed complex interrelationships in the long-term evolutionary process of nature. The chemical substances released by plants or animals play an important role in information communication and form extremely complex The information network. A lot of people are interested in this kind of chemical information communication, but so far, what we have learned is only scratches the surface."

Thinking that Feng Yi is not professional in the field of theoretical knowledge, Professor Ding changed his words, "When it comes to this, you have to mention the sense of smell. For example, if you are sensitive to a certain substance, when you smell it, the olfactory organs are related. Olfactory receptors are activated to form specific olfactory receptor pathways. 'Olfactory receptors', you know? They are special proteins that can bind to odor molecules and are responsible for transmitting odor signals to the brain."

Feng Yi nodded: "Well, I know."

"Generally, we believe that the more 'olfactory receptor' genes we have, the stronger the sense of smell. Different species have different sense of smell. We humans have about 400 species, which can only be considered average in this regard."

Professor Ding has nothing else to do now, so he is sitting on the edge of the flower bed.

"For example, this dog, the dog's sense of smell is much stronger than the human..."

Professor Ding waved to the black dog.

The **** dog came wagging its tail, and then, the long raised mouth was caught.

The dog has more facial expressions than the wolf. The most spiritual thing is the muscles at the position of its eyebrows. The trembling and shaking, coupled with the hesitantly wagging tail, can directly show its inner activities at this time.

However, Professor Ding did not care about its small psychology at this time.

"When it smells, one part of the air goes to the respiratory system, the other part..."

Professor Gu Huding's fingertips moved along the central axis above the dog's nose, moved between the two eyes, and tapped lightly:

"...they lead to the olfactory crypt. Odor molecules perform olfactory detection on this special structure. They can precisely identify an odor in a complex environment, and even know which odors are smelled by which nostril. "

After loosening the **** dog's long beak, Professor Ding looked up and saw the flying birds passing by in the sky:

"For example, this bird, in people's general cognition, except for some birds such as vultures that hunt by smell, most other birds have almost no sense of smell. But their genes tell us that this is not the case, and genome sequencing can It was found that many birds have olfactory receptor genes, with less than 100 genes and more than 600 genes.

"Looking at the evolutionary tree shows that the ancestors of birds probably had very diverse olfactory receptor genes that allowed them to distinguish some important odor information. There are a lot of chemical information they are insensitive, and they are sensitive information that we do not know, or Little is known."

Professor Ding looked at Feng Yi: "If you want to study the chemical information communication between species, you can't think about it from a human perspective. Their olfactory world is different from ours. You can't imagine the world they perceive. What a world."

Feng Yi, who felt a different world: "...you're right."

Thinking of something, Professor Ding smiled again and said, "No, no, no, I was wrong just now. I said it too absolutely. We are the same people, you are different from us!"

Feng Yi's heart skipped a beat, but his expression remained unchanged and his face was calm: "What's the difference?"

Professor Ding: "For example, you are sensitive to the smell of snakes, and you can smell smells that we can't smell. You may have more olfactory genes than most of us. There are indeed a small number of people in the world, to be precise, they are There are very few people whose sense of smell is hypersensitive. You're lucky to be one of them."

Feng Yi took a long breath without a trace and said, "There are differences in individuals."

"Yes, that's it. But no matter what, we humans can't compare with those species with a strong sense of smell." Professor Ding sighed, "I now hope that the electronic nose can be upgraded quickly, maybe one day I will be able to use the instrument to know that it has a strong sense of smell. Species with gifted sense of smell, what kind of world do they see. Are you looking forward to it too?"

Feng Yi: "...Well."

Professor Ding complained again, "Human smell receptors are not good enough, there are many ideas, they may not all be in your nose, they may be in some strange places!"

Feng Yi was curious: "For example?"

Professor Ding: "For example, the hair follicle. If it smells some 'correct' odor, it will be specifically activated. Although it won't tell you what it smells like, it can prevent the hair follicle from degenerating, or - prevent hair loss!"

Not far away, a young worker with burning eyes couldn't help but say, "So, where can I buy this 'correct' scent?"

Professor Ding touched the top of his slightly bald head, "Ah, I want to know too."

Feng Yi had no other problems, so Professor Ding began to discuss with the man how to prevent slipping gracefully.

Feng Yi has no such troubles for the time being, so he will not participate in their discussions.

Walking into the street, he put on the hood of his sweater and his sunglasses. Feng Yi took a shared bicycle and came to a small park near the sea.

Xiaojia said that there are not many tourists here, and this time period is not a time when there are many people.

The weather is fine today with a sea breeze blowing.

There was no one here at this time, but it was not deserted, and there were sparrows chattering in the trees.

The sparrows here are very courageous. It can be seen that whether tourists or local residents here, they are very friendly to them. From time to time, they form groups and get some food from people actively or passively.

Probably full of food, each one is very active among the branches.

A few of them stared at Feng Yi, but turned away disinterestedly. Even if Feng Yi approached, he just fluttered his wings and jumped perfunctorily, and then continued to ignore it.

Feng Yi recognized the direction of the wind and raised his hand towards the sparrows on the tree.

The pupils of both eyes behind the sunglasses gradually became vertical.

The chemicals that ordinary people can't see or smell, emanate from the skin of the palm, towards the group of sparrows.

Organisms that are insensitive to this chemical information substance cannot perceive anything, but they can feel it differently.

This group of sparrows seems to have seen a bloodbath with two fangs attacking!

The sparrows who were distracted suddenly screamed and flew away in a panic.

A sparrow won't cause much noise, but a group of sparrows suddenly flutters away like a refugee, and UU reading www.uukanshu.com will inevitably attract the attention of nearby people.

People scattered all over the place looked at that corner and saw nothing. There was only one person in a sweater sitting there basking in the sun, and the others were nothing special.

The wind from the sea blew away those things in the air that could not be seen or smelled.

Everything was still as good as before.

"Is there another wild cat coming to catch sparrows?" said an old lady.

"Not necessarily, sparrows are always surprised."

"No, the sparrows here are bold!"

"It's alright, they'll be flying back in a while."

However, until the sun went down, the sparrows that flew away did not fly back to the tree. At most, they just stomped on other branches of the park, but not a single sparrow flew past that corner.
