Which organism has contributed the most to human biology?

A monkey? rabbit? Pigeon? little white mouse?

If you really want to let biology researchers choose one, then many people should give such an answer-Drosophila.

Drosophila, since Morgan's time, has been used on a large scale.

Its advantages are countless. As a species of Diptera in the Insect class, fruit flies, like most of their relatives, have the advantages of "strong reproductive ability and short life cycle".

Moreover, like most Diptera Insects, it has a very high tolerance for "life".

A random empty bottle, pierce some small holes, throw in some rotten fruits that humans don’t eat, and fruit flies can reproduce in large numbers.

Furthermore, at a room temperature of 25 degrees Celsius, fruit flies can reproduce one generation every ten days.

From egg to sexual maturity to reproduction, it only takes ten days.

Finally, fruit flies have only four pairs of chromosomes, which are few in number and have obvious differences in shape.

Depending on the huge population, there are many variations in Drosophila traits, such as the color of the eyes and the shape of the wings.

Therefore, Morgan can simply use the naturally obtained white-eyed fruit flies to verify the genetic laws summarized by Mendel.

It can be said that it is from this kind of small animal that human cognition of "biology" has been completely changed.

This is simply an ideal laboratory animal.

Unless the experimental project is related to the high level nervous system, any geneticist with normal IQ will abandon this species that seems to be born to enter the laboratory, instead of going there will be 23 What about large primates that have many chromosomes and traits that are difficult to master, require at least sixteen years of sexual maturity, and have strict requirements on diet and environment, to do inhuman experiments in the laboratory?

Even if a technology is finally implemented on the "human body", the "human body experiment" can only be the last step.

Before this, there are more good species with short life cycles that can help researchers explore unknown mysteries.

And this time, as if its family once helped Morgan, these little creatures helped Yoggmov once again took a solid step.

Yoggmov’s agar is almost the first instar larva of Drosophila [the larva that has just hatched from the egg until the first molting is called the "first instar", and the second after the first molting The one before molting is called the second age, and so on] This thing is less than 0.5 mm, which looks much worse than the dust at worst.

Xiang Shan can only see the squirming dots.

However, there is no doubt that it is the result of the mating of those fruit flies.

Xiang Shan felt his heart beaten hard. He opened his mouth and asked: "Isn't it said that there will be occasional natural mating? The birth of these eggs is accidental?"

Yoggmov shrugged: "No, just a few metal base fruits Flies can also pa pa pa. Probably because the self-repair mechanism of genes has reshaped the'sentences' related to reproduction, allowing the inserted foreign genetic information to enter the process of sexual reproduction."

"Huh?"

Yoggmov nodded: "In terms you are more familiar with. The genetic information of each organism is actually an'information library'. And our genetic material and enzyme system are just It forms the sentence that'calls' these genetic information."

"The original calling sentence matches the database. It is precisely because of this that the genetic information will be expressed in different forms. Therefore, the two species that share a large number of genes will show different forms."

"And we cracked the enzyme system, so I can insert some foreign information a little bit. This is also true. It’s the metal-based cell you’ve seen before. However, compatibility with these external information is problematic. So, when the life’s program is running and you want to call part of the information to make it work at an appropriate time, It has a bug."

Xiang Shan froze for a moment: "So'forgot to reproduce' is just a vicious bug?"

Yoggmov nodded: "Yes, bug. "

Xiang Shan patted a cold sticker on his forehead: "That's it. There should be no more vicious bug than this in evolutionary history. No matter how vicious, the degree is about the same-it can The race will be completely emptied in a generation."

"But I still like a line in "Jurassic Park", "Life will find its own way out"." Yoggmov pointed to Drosophila: "A small number of fruit flies have automatically fixed this bug."

Xiang Shan pressed his forehead: "This thing cannot count on luck..."

"No, not expect Luck." Yoggmov is very confident: "As long as it happens once, it means that it can indeed happen under certain conditions. As long as we master the'condition' and control the variables, I want it to happen repeatedly several times. No problem."

Gene has a strong ability to repair itself. This is a built-in mechanism.

After all, the RNA and DNA used by Earth organisms to store genetic information are really fragile. If the thin, high-energy particles from the universe accidentally hit it, it may cause a small amount of information to be written or erased, rewriting the password of life. Viruses can also do this. There are even many organic poisons that can cause damage to it.

But genetic information is still largely stable. When the "error" is not serious, the genetic system also has the ability to self-correct.

This process is happening all the time.

"In other words, you think there is an unknown process or effect that can compensate for this bug, at least to prevent our'system' from crashing." Xiang Shan nodded: "And it has appeared in You face it. And what you have to do is to compare the genomes of these self-repairing fruit flies with those of the uncompleted self-repairing fruit flies, and confirm that the genetic modification surgery has destroyed those genes and caused this mechanism. Invalid?"

"Almost." Yoggmov nodded: "This process will be completed soon."

"Oh, I probably understand why you have to come here. "Xiang Shan Shen sighed: "Let's talk, what do you need?"

"The computer I originally asked you to order is definitely not enough. The data to run is more than expected... "

"Day!" Xiang Shan made a middle finger: "The order has been impossible to cancel! Do you think it is a home computer, can you return it for no reason before it arrives? That is for research institutions... …"

"Oh, keep those equipment too. I want to add better computer equipment."

Xiang Shan looked at Yoggmov: "Brother, our research I just put up a sign, and what about the funding... If it’s not for me to take the subway to go home later, I’ll pull a handful of my hair and show you what you believe?"

"Pull out my hair "?" Yoggmov wondered: "Is this any strange Republican customs?"

"No, it's showing my powerless and crazy heart." Xiang Shan walked to the door and picked it up from the coat rack. He lifted his jacket, then put his hand in his pocket and fumbled for a few times: "Of course, if the equipment is not available, I brought the wine for celebration."

Although the temperature in the laboratory can be turned over burly man, but Xiang Shan's quilted jacket has good insulation properties, so this palm-size bottle of Red Star Erguotou actually has a hint of coolness.

Yoggmov was surprised: "I thought I could open a bottle of champagne."

"There was no wine. When I came, I remembered it, so I bought it at the junction shop. I'm picky." Xiang Shan shook his head: "Where you live and follow the customs. Our old Beiping is just like this-come and come."

Yoggmov took a sip directly on the bottle.

Then I want to spray it out.

But after realizing that he might sip the fruit flies with a sip of wine, the man swallowed this unimaginable pungent liquid.

"What am I drinking? A cold fire?"

"This is the taste of victory, brother."

Two men This is to lean against the coldest wall in the laboratory, sit upright on the ground, and then share a bottle of "Taste of Victory".

"I think it's good." Said a scientist from the United States whose accent was slightly changed by alcohol.

Xiang Shan nodded.

He sat on the ground and looked at the fruit flies. He felt that the orange light from the heater was like circles of golden light.

In the worm net, the future of golden is shining.

…………………………………………………………………………

"Gan." Xiang Shan pulled out again I disconnected the wiring on my body and withdrew from this reading.

He is now sitting on the ground leaning against the inner wall of the vehicle, the same posture as before.

But it was pitch black directly opposite.

The extraordinary vision given to him by the prosthetic eye let him know that he was directly opposite to the barrels of refrigerant he had previously stocked.

"Am I an idiot? What eyesight? What rhetoric? The feeling of'seeing the future in a worm net'...hahahahaha, what a joke."

" Now this World is really fucking like being locked in a worm net."

"I was only a promise in 28 years. I had a brain hole in 37 years."

Xiang Shan started to treat this The memory feels disgusting.

Although the high spirits in his heart told him, this is indeed his own memory.

The "memory of subjective emotions" that he segmented out still echoed in his brain, reminding him of this.

However, Xiang Shan really couldn't contain his anger.

He simply put away the hard drive, then kicked the door open and rushed out.

Single-killer Jadel is photographing on a rock, observing the south with his homemade optical instrument. At this moment, the afterglow of the sun is gradually disappearing. It's time to start again.

Xiang Shan walked to the single-killer king and asked, "Brother, did you find anything?"

"Well, it's nothing. Amirkale brought back some troops. It’s just that the whole city has sunk below the horizon. I can’t see the movement of their ground troops, so I don’t know how many people have been brought back."

Speaking of which, the single kill king sighed: "Sure enough, I should leave a hidden command in that anti-aircraft gun position and let it fire after ten hours' countdown."
