After thinking for a few minutes, Hou Zhijie spoke slowly.

"Just looking at this genetic map, I can only be sure of one thing, that is, about 100,000 years ago, other higher intelligent creatures might have had intersections with creatures on Earth."

"As for what this higher intelligent creature is, what purpose it is, and what kind of intersection it has, there is no way to judge at present."

"However, this period of time was worth noting a hundred thousand years ago."

"According to the consensus of the research community, the earth experienced a mass extinction between 70,000 and 130,000 years ago, and the history of human evolution also had a clear period of time."

"It seems that there may be deeper reasons behind that gap in human evolution history." Hou Zhijie stopped talking after saying this.

There is no factual guess, no need to say it, and there is evidence to speak. This is the necessary quality of a scientific worker.

"The gene from 100,000 years ago became extinct in 70,000 years ago."

"It's really a coincidence."

"Either science or history, all coincidences are not accidents. It seems coincidences, but they must have their own internal reasons."

"perhaps."

Cheng Xiang looked at the familiar double helix on the big screen, "Perhaps, we can find something among these genes."

Having an idea in his mind, Cheng Xiang immediately operated the computer and couldn't help but frown when he saw the project file with a volume of less than 300M.

"Director Hou, can we estimate the weight of DNA in the box?"

"Yes, based on the summary data previously transmitted by the space center, it is estimated that the weight of all DNA in the box is about ten kilograms, and the error does not exceed 5/1000." Hou Zhijie quickly answered.

"Ten kilograms!" Hearing this weight, Cheng Xiang looked at the project documents again, and saw the 300M documents and frowned.

"The genetic sequence information that needs to be collected with a weight of ten kilograms is too huge. Not to mention the limited speed of the detection equipment, even if it can be detected, it will not work completely by relying on electromagnetic waves to transmit data from Mars to the Earth."

Cheng Xiang frowned and said.

Hou Zhijie agreed after hearing this: "The average molecular weight of the base pair after dehydration is 614, which is easy to calculate and estimate to 600. Then the base pair on 1 gram of DNA will reach about the order of magnitude of 10 to the power of 21."

"Even if we don't describe the molecular formula on the base pair next, we only transmit the base pair tags. At the current rate of 300MB per hour, if a bit represents a base pair, it will take about 4.2 times 10 to the power of 11 hours, which is about 17 billion days, nearly 50 million years."

"So, theoretically, with current technology, it is impossible to transmit complete data by relying on electromagnetic waves."

Cheng Xiang nodded in agreement, "This is indeed a problem. However, for the time being, we should have a clear idea. Let's study the information on our hands first."

"See if you can see something. If you can find something valuable, then make other plans."

Hou Zhijie agreed with Cheng Xiang's view that at present, this is the most appropriate way to do it, so the topic said, "As far as I understand, the Zhurong IV satellite deployed in Mars synchronous orbit is about 300MB per hour. With our authority, under emergency missions, those who can apply for it in one day should be able to reach 200MB per hour."

Mars exploration and communication resources are always tight. It is rare to apply for 200MB per day, accounting for two-thirds of the total bandwidth. LOL Novel Network lolxsw.com LOL Novel Network

"200MB per hour, and one day, it's about 2.5G."

Cheng Xiang nodded, "This preliminary study on the amount of data should be enough."

"Let's have a short meeting first and see how to start."

"good!"

After a period of discussion, the meeting finally decided to split half of the manpower from the original team and devote themselves to the research of unknown genes on Mars.

After the task was divided, it was already three o'clock in the morning.

However, from the expressions of everyone, there was no sign of sleepiness. Each of them looked both excited and solemn.

However, who else should I sleep? Research is a long-term task.

In a blink of an eye, it was already the next night.

The space center sent the data received today to the Galaxy Research Institute on time at around 8 o'clock in the evening.

The hard disk data is about 2G, but it has not reached the estimated 2.5G. It is not that the estimate cannot be accurate, but that with current communication technology, communication can only be done in tens of millions or even hundreds of millions of kilometers away.

The data link will not be stable all the time, so it is already quite good to get 2G data in one day.

Since yesterday, I received the data and started calculating, the time was not enough 24 hours, and I could have 2G data. The space center has considered that the pace data time was advanced, so it temporarily increased the hourly bandwidth allocated today. Otherwise, even the 2G data volume would not be enough.

Looking back more than ten years ago, at that time, the Mars synchronous orbit satellite had not been deployed, and Mars' high-altitude relay satellites were even more unthinkable.

At that time, we could only rely on signal transmitting devices on the ground of Mars for communication. The transmission speed of one hour was less than 100MB, and due to the rotation of the planet, we could only send a few hours a day. Compared to that time, the situation is much better now.

At this time, at 8 o'clock in the evening, after Cheng Xiang had processed other daily work, he heard the data and immediately rushed to the ninth floor underground.

By the time Cheng Xiang arrived, Hou Zhijie was already waiting in his seat.

"Director Cheng, the data has been sent."

"According to our requirements, the data stored here is in 49 small boxes, including the first 200MB of the genes in the boxes numbered 1-10."

"Very good, give me one."

"Then according to yesterday's arrangement, allocate the remaining data to each group."

"good."

Hou Zhijie was very straightforward in doing things and immediately handed the hard drive to Cheng Xiang.

Cheng Xiang took it and sat down immediately. After skillfully connecting the hard disk, he passed the verification and opened the hard disk space and immediately saw the familiar project file.

After copying the project files to a confidential computer, Cheng Xiang returned the hard drive to Hou Zhijie.

After returning the hard drive, Cheng Xiang immediately devoted himself to work, double-clicked, and the project file was quickly loaded.

The familiar double helix structure suddenly appeared in front of us. Today's data, compared to yesterday, is not only ten times larger in the data volume, but more importantly, the data sent from Mars today has omitted the structural description of the molecular formula and is directly sent as base pair markers.

Therefore, the amount of the gene data presented in front of me is more than ten times higher than yesterday. It saves the structural description of each base molecular formula, and the base pair capacity of this gene sequencing project file has soared by hundreds of times.

Therefore, the data volume reaches 2G, which may be too different from the DNA information in the entire box. However, some simple research has already achieved certain reference value.
