Li Menghua stood outside the deer park of the Institute of Zoology of the Chinese Academy of Sciences, looking at the deer park, and the iron pipe with thick arms formed a grid in front of him. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

These fences were originally intended for wildebeest and elk, but now they are inhabited by Beiyang pheasants.

The giant chicken was eventually named Beiyang Giant Free-range Native Chicken, referred to as Beiyang Chicken.

Only a few days later, the Beiyang chicken was bigger, and Li Menghua could no longer see the back of the Beiyang chicken when he was standing.

'Beiyang chicken can already be ridden as a horse! ’

Li Menghua thought of Li Jinxuan, who had to listen to stories to sleep, it was not okay not to tell it, she would always look at you with her eyes, round, with a little water, like a wronged cat. In the face of this kind of look, it was Yu Mei who was defeated first, and then the two of them defeated him together, the story still has to be told, and it may have to be doubled.

If a goose grows so big, it can directly play "Niels Travels on a Goose." ’

"Mr. Li, the data of Beiyang chicken has been measured, and it is all here." Tian Haibo handed over a few forms.

After receiving the measurement data, Li Menghua found that Tian Haibo was wearing a new pair of shoes, and the new shoes were still the same jeans that had been worn for a long time, with unkempt hair, thin and pale, sunken cheeks, glasses, and a student-like look.

"I just bought it yesterday?"

"Hmm."

"If you can't find a girlfriend like this, you should wash your hair at least every two days and change your clothes once a week."

Tian Haibo smiled embarrassedly and scratched his hair even more messily with his hands.

Li Menghua frowned, this is a smart kid, extremely smart, he can kill layers of screening, and if he is admitted to his doctoral program, his IQ cannot be lower than 150.

Li Menghua likes technical talents, but Tian Haibo is a bit extreme, he seems to only learn and engage in technology, and he doesn't know anything else, and he doesn't even know how to live.

"Don't you like beautiful women? Or are you planning to marry a rural girl who has graduated from junior high school? ”

Another embarrassed laugh.

Li Menghua rubbed his temples and stopped talking.

Forget it, this kind of life is purer, maybe better!

"What are the measurements?"

Li Menghua didn't look at the form, but rolled it up in his hand, and he didn't mean to read it at all.

"Six Northern Yang pheasants, females with an average shoulder height of 182 cm, males with an average body width of 187 cm, females with an average body width of 146 cm, males with an average body width of 150 cm, and leg length ......"

"Don't memorize the data," Li Menghua believes that Tian Haibo will not be wrong with a decimal point, even if he has only read it once.

"Give me the conclusions, what conclusions can be drawn from this data? Your conclusions. ”

was said, Tian Haibo scratched his hair.

"The bones of Beiyang chicken and native chicken are basically the same, the bone density and bone diameter of some load-bearing bones have increased, the muscle groups are consistent, and the overall shape has not changed; consistent internal organs in body cavities; Fat percentage data are close; Tissue conductivity data are similar; proximity of body temperature; a slight decrease in the rate of the heartbeat; The feather density increased, and the number and length of hard feathers increased......"

"On the whole, Beiyang chicken is almost an enlarged version of ordinary domestic chickens."

"Has your intelligence been tested?"

"I've measured it, and there is no obvious change."

"Since the ratio is magnified, then the brain volume must have increased dozens of times, why hasn't the intelligence changed? How to explain it? ”

"The key is structure, brain capacity is not equal to intelligence, the right structure is the key, otherwise the elephant should be the smartest."

"Have habits and instincts changed?"

"No changes were observed."

Li Menghua shook his head, "There will be changes, the body size has changed so much, the cognitive environment has changed, and the domestication and rewilding conditions will definitely change." ”

Li Menghua thought for a while, and said, "Animals are very sensitive to body shape, and they usually equate body shape with strength and weakness, and changes in body shape will inevitably bring about changes in obedience. ”

"Okay, I'll keep an eye on it."

"Well, usually pay attention to safety, ostriches can kick people to death, and Beiyang chickens can too."

"Okay."

Tian Haibo simply agreed.

Li Menghua nodded, as long as he agreed, he could rest assured, and there would be no problem with the rigorous attitude of this student during the experiment.

"For the appearance of Beiyang chicken, tell me what you think."

"Beiyang chickens should not be hybrid mutations, two thousand Beiyang chickens, it is impossible to mutate so consistently; But she should not be a natural variation, and natural variation should not be so consistent. ”

"What should that be? There should be a reason. ”

"I feel a lot like gene editing technology."

Li Menghua also considered this possibility, but it shouldn't be.

"Gene editing technology is far from mature and shouldn't have such precise control. Genes and molecular-level biochemical reactions under gene control are still in a gray box state, a few are known, most are unknown, and I have not heard of any institution at home and abroad that can lift the growth lock of organisms, and it is still so perfect. ”

"But apart from purposeful, targeted gene editing, it's hard to imagine any other way to mass-produce gigantic organisms."

"Perhaps, there are some coincidences, coincidences that we don't know about, that just lead to gigantic mutations."

"But it's too neatly mutated."

"Nope! It's not neat! ”

Li Menghua spat out a few accents.

"In fact, these two thousand Beiyang chickens are only the mutated part, and there are more than 3,000 that have not mutated."

“...... This ......"

Tian Haibo didn't know how to explain it.

"The answer is there, it's up to us to catch it."

The answer needs further means, morphological observation, trait observation are all auxiliary.

"Go back and do the gene sequencing of the Beiyang chicken, and then test the genetic map of the same batch of chicks. I'm going to compare the data in detail to see which genes are at work. ”

"Okay."

"We're going to move fast!"

Need to speed things up anyway!

I just learned that the director of the soup field regarded Beiyang chicken as a strange commodity and sold it all over the world, even the University of Helsinki got one, and the former colleague also asked about the progress here.

This is likely to be the world's first mass gigantic genetic mutation, which is of great scientific and commercial value!

There are 18,000 genomes in chickens, a billion base pairs, and identifying the differential genes is only the first step, and the next step is to identify them, remove the useless base pairs, and find the base pairs that really work.

It's a big project.

But if the answer is found, the growth lock and the gigantic gene will be found.

That would be the next Nobel Prize!

PS: Sorry! It's so late!
