The night is very dark, very quiet, very cold, there are very few stars in the sky, the moon is not full, the light is dim, who will appreciate such a night?

Duan Pingsi leaned alone on the overpass across 121 Street, watching the cars coming and going, looking at the bright lights, the heat in his heart could not be calmed, there were some things that needed to be thought about.

"Dali Guo, Duan Siping, Time Bubble, Traveling, Old Ancestor, Ape Head, Professor A, Zhang Yu, DNA Extraction, Gene Sequencing, TOM Biology, Law of Attraction, 12:12......"

In just a few days, Duan Pingsi's life suddenly came into contact with a large number of new words, and even met an ancient man who traveled from more than a thousand years ago to the modern era, and the plot became more and more bloody.

According to the theories of Einstein, Hawking and others, it is not impossible to travel through time and space, and parallel universes may also exist, but when there is really an ancient person talking to you across time and space, what a shocking and terrifying thing it is.

People with a little common sense know that this kind of thing should not be talked about with others, otherwise the world will be in chaos at best, and it will lead to death.

Human beings are greedy by nature, and when an advanced idea or weapon is in the hands of someone with bad intentions, it will lead to an imbalance of personal rights, the consequences of which are unpredictable.

Duan Pingsi was holding such a "weapon" at the moment, and before his safety was confirmed, he could definitely only know about this matter.

Looking up at this dark space, is there any life in the vast universe that can understand such a feeling? A star blinked, as if in response to the human loner's question.

"Can you hear me?" Duan Pingsi asked the brightest star.

The star blinked again, as if in response.

"Really? Can you understand my mood at the moment? If so, would you please blink ten times? Duan Pingsi asked casually, he needed someone who could share his secrets so much.

The miracle came so suddenly, and the truth seemed to come again. The star seemed to understand Duan Pingsi's words, and when he spoke, it shone brightly and darkly.

“1，2，3，4，5，6，7，8，9，10。” The star flashed ten times, no more, no less.

"Oh my God, hell again!" Duan Pingsi exclaimed.

The star's response once again stunned the hairy boy of humanity, who stood aloof and seemed to mock humanity's arrogance, complacency, and ignorance. Duan Pingsi didn't dare to ask any more questions, he was afraid of getting an answer from space.

"Recently, I have eaten too many pig's trotters on Yuanxi Road, and I am afraid that it is a little hot."

He rubbed his itchy eyes vigorously, and when he looked into space again, he didn't see any stars, he was very sure that what had just happened was caused by his own dazzle, and that it was not worth worrying about, that he had enough troubles.

With fewer and fewer vehicles coming and going, it's time to go back to sleep.

Three days later, Prof. A and Duan Pingsi received the sequencing results from TOM, and after rigorous sequence comparison, they came to an astonishing conclusion:

The genetic sequence of the sample was 99.0% similar to that of chimpanzees, and 99.9% to modern humans, in other words, the species with the suspected "ape" head was more likely to be a modern human.

"Humans? This is absolutely impossible, it must have been contaminated with human genes during gene extraction or sequencing! ”

Professor A couldn't believe that the "ape" was brought back from the Jade Dragon Snow Mountain by himself, and no matter what kind of characteristics it was identified, the result could not be human.

"Let's do it all over again!"

While announcing the failure of the experiment, Professor A immediately went into battle himself, re-extracted the genes, and asked Duan Pingsi to send the newly extracted DNA samples to TOM for a second sequencing.

However, the sequence sent back by TOM three days later showed exactly the same results as the first sequencing – the sample was most likely a modern human.

"Could it be that we really brought back a human head?"

Both were shocked by the same result twice. After thinking about it, in order to avoid some unnecessary troubles in criminal liability, Professor A finally chose to call the police to deal with the matter.

The young police officer Tan Rong came with the forensic doctor, and the two came to different conclusions after a thorough investigation and questioning, and the forensic doctor said: "I can be sure that this is not a human head, you don't have to be nervous, judging from the scene, this should be the head of an ape, what kind of it is, then it depends on you to identify, you are experts in these aspects!" ”

Professor A and Duan Pingsi were both greatly relieved, as long as it was not a human head, then there would not be much of a problem, and it was still legally permissible to store some animal carcasses in the laboratory.

"Although let's run for nothing," Officer Tan Rong said with a smile, "but your legal awareness is very strong, which is commendable, you can study this thing slowly, and remember to tell me when you determine its species." ”

"Are there any close human relatives who have not been discovered? No, how can such a high degree of similarity not be the same species as humans? It's messed up, it's messed up, biology is going to be messed up......"

After sending off the police and the forensic doctor, Professor Ah sat on the sofa and pondered these questions repeatedly, and now he was in dire need of inspiration and a breakthrough in the problem.

Duan Pingsi stood aside, also lost in thought, he suddenly had a big conjecture, since this species is a close relative of humans, but it is not a known close relative, and its similarity is higher than that of gorillas and chimpanzees, then it cannot be an existing species.

"Professor Ah, do you think this thing is not a modern species?" He finally couldn't help but ask.

"What species do you say?" Professor A looked at Duan Pingsi blankly as if he had discovered a new world.

"I said it wouldn't be a modern species at all." Duan Pingsi repeated.

"Not a modern species?" Professor Ah shook his head, "How is that possible?" Is there still a way to cross it? ”

"Crossing? No! That's not what it means! Duan Pingsi really broke out in a cold sweat, he had indeed thought of this bizarre possibility, but he would not mention these two words to anyone now no matter what, it was too risky.

"I see what you mean, hahaha!" Professor A suddenly laughed, "It's a snow mountain, the Jade Dragon Snow Mountain was formed tens of millions of years ago, it should be the best refrigerator, why can't you freeze some prehistoric food?" ”

Treating the Jade Dragon Snow Mountain as a natural refrigerator and comparing the "ape" head to food, this is probably Professor A's initiative, Duan Pingsi felt a little disgusting but had to admit that this metaphor was indeed very appropriate.

"I'm just guessing, but the food is so well preserved, like fresh, it's hard to do that with modern technology, right?"

Duan Pingsi immediately learned Professor A's metaphorical technique ten percent, who would have thought that this old and young man would have such a special hobby?
