"It looks like grandma's coat is pretty good?"

"Yes. Her physical condition has been maintained quite well. Other monkeys enter menopause at the age of three and age immediately afterwards. Until now, she still maintains normal estrus every year. The cumulative number of children she has given birth to is much more than other monkeys.

But we haven’t let her give birth to monkeys in the past two years.”

"Monkey version of the old monster?" Lan Ze sighed, and then asked, "Are these monkeys around? Are they hers..."

Lan Ze wanted to ask if it was a harem, but it didn’t look like it. A male monkey can have a harem only after he becomes the monkey king. No matter how high the status of a female monkey is, she usually has only one fixed partner. This is true for all primates. The "system" of marriage is written

in the genes of the species.

"They are all her daughters. The daughters with mutations have lived longer and have always been with the grandmother, so they are more favored. She also likes the younger daughters better. The one who is receiving grooming now is her youngest daughter.

"

"With so many monkeys, what have you observed?"

"There are many things. The most intuitive one is lifespan. You have seen it, right? For another example, we found that the old lady and her mutant offspring are a little smarter than ordinary monkeys. Because they live longer and take longer to learn. So.

, their intelligence scores are higher when passing animal behavior tests."

"How much higher can it be?"

"A little bit. But enough to make a statistical difference."

"There are two questions that I am more concerned about." Lan Ze considered it for a moment. "One is whether the length of the developmental period has changed, and how much has it changed? The second question is, at what stage of monkeys are your animal behavior tests aimed at?

, have you conducted comparative tests on young monkeys at different stages?”

"...You spoke too quickly. Say it again and I will remember it."

De. Lanze already knows at least half of the answers. If she is familiar with both questions, there is no need to say it again.

So nine times out of ten, the question comes to the blind spot of animal experiments.

He repeated the question slowly and watched as LLL recorded his question.

"I can answer your first question now. The development period is indeed slightly extended. However, the price should be worth it, right?"

"The cost? So how much is the developmental period delayed?"

"What we record is the time of the first heat."

"That's okay."

"Marmosets are non-seasonal breeding species, very similar to humans. They can reproduce throughout the year and have a very short estrous cycle. The genetic effect of this mutation is very stable. Female monkeys carrying the mutation will mature sexually one month to one and a half months later on average.

"

"What about the second question?"

"It may be in the experimental data, but no analysis has been done in this area before."

"Can I see the raw data?"

"As long as the old director agrees."

"I think...I've really calmed down. Go back?"

"Let's watch the monkeys for a while. It doesn't cost any money." LLL advised him.

"The guest can do as he pleases," Lan Ze said helplessly.

The institute is not a big place, but the roads are a bit circuitous.

Mo Mo tried to reach out and pat the breeding box. Lan Ze quickly took a step back.

Mo Mo protested: "Oh? Houji——"

"You can only look at it, but you can't touch it."

"Oh." The child nodded solemnly.

"Look, you have such a wonderful mutation. You have an ageless appearance and a long life. If you convert the age of the old lady, it is equivalent to 300 years of human years. Don't you think she is a monkey beauty?" LLL looked at the monkey grandmother and said.

, I don’t know what she is thinking.

"Monkeys are not people, and people are not monkeys." With Lanze's level of knowledge, he would not be deceived by this superficial beauty. "There are too many factors related to life span. This little thing can only live four years."

Years. It’s not that difficult to turn eighteen. By the way, why is the grandma a little bigger? Is it related to the mutation? "

"Ah, that. It shouldn't matter. Before knocking out the gene for the old lady, when artificially synthesizing the fertilized eggs, we chose the strongest monkey from both parents. She should grow older."

Lan Ze was still guessing whether the mutation had unpredictable effects. It seemed...

"These are inbred monkeys." He looked at the monkeys in front of his eyes, but what he was thinking about was humans.

"It's okay, after all, their mission in life is to conduct experiments. These standard experimental animals cannot survive in nature. And it's not considered inbreeding. Their population is quite large, and the only ones that can be paired are at least cousins.

"

Xiao Mo Mo stared at the monkeys intently, observing the family soap opera of little monkey Ji. Adults would not understand what is so charming about monkeys.

"I think even if people are not monkeys and their life span cannot reach 300 years, as long as they can easily exceed 100 years old, it is a great breakthrough." LLL said happily, "You can also live longer by lowering your metabolism, but this is obvious

There is no need to lower metabolism. I think this is the right way to extend human lifespan. And currently, it seems that this is a fairly safe mutation."

"Do you have many types of mutations?"

"There are quite a few. Some of them have rather strange effects. There are seemingly unrelated changes in traits between the first and second generation mutation carriers. There are not many things of real value, and most of them can only be used as human bodies.

The reserve of the database. The old director thinks very highly of your mutation. In his opinion, just living a long life is meaningless. Maybe because of his age, he cares about the quality of life."

"Have you...ever considered a question?"

"Um?"

"The particularity of human beings is that they are highly social animals. Any mutation that may affect social behavior may have a major impact on human society. Have you done any research on this?"

LLL was silent for a while: "...You have also seen it. We can study monkeys. But for humans themselves, we can only use tracking and observation. We... belong to the Institute of Biochemistry, not the Institute of Sociology. And...

There are simply too few samples for some mutations."

"There are few samples, so why are you looking for me to induce the baby?"

"Is there any other way?" Sister Xiaolu asked seriously.

On the way away from the monkey, Mo Mo kept chanting "monkey ji, monkey ji" in a low voice. When he arrived outside the old director's small living room, he suddenly became serious. His eyes widened and he said nothing.

Lanhua and the old director were chatting happily.

LLL sent Lan Ze in and replenished the tea. Xiao Jiang stayed outside the door as usual.

The old director picked up the tea cup and looked at Lan Ze with a smile while drinking tea.

"Are monkeys good-looking?" Lanhua asked Lanze.

"It's okay. Very hardcore."

"Want to take a look?" The old director spoke very gently to Lanhua, just like he would a small animal or a child. "It just so happens that I can chat with him alone for a while."
