This is the dark and empty space, and the nearest star is about a light-year away, and Wei Feng has been sailing alone in this vast universe for more than three hundred years. Under such circumstances, Wei Feng opened a device taken from space in the Star Ocean spaceship, and then saw a ...... that definitely did not belong to the known scope of any human civilization Creature.

It undoubtedly belongs to the category of biology. Wei Feng could even tell its thinking organs and torso from its appearance. It was frozen in a pale blue transparent solid, motionless, like an amber. It had a large head and a thin torso, as well as skin covered in what appeared to be scales or something. It looks like a freak.

The most terrifying thing is that above its head, two places that seem to be light receptors are wide open, and two black eyeball-like objects are quietly staring upward. When Wei Feng had just come over to check the internal situation, Wei Feng's gaze happened to meet these eyes.

One can imagine how huge the impact this will have on Wei Feng, which is so great that even if Wei Feng has undergone more than 20 years of professional training and hundreds of years of long-distance training, he will be a little unbearable for a while. It took a few minutes for Wei Feng to come to his senses, then he stood up again, and walked over to the hibernation pod once again, carefully examining everything inside.

Ye Luo's voice sounded at this time: "Captain, whether this alien died because we cut off the energy supply, this matter needs further analysis to come to a conclusion." After all, this device has been around for too long, and it is highly likely that it died before we found it. ”

Wei Feng did not respond to this sentence, but still observed carefully, and said slowly: "Look, this should be its light receptor. Since it can evolve eyes, it means that there must be plenty of light on the planet where it was born, which means that the planet must be near a star. Well, no, its visual receptors are larger than those of us humans. This suggests that although there is light on the planet it lives on, the intensity of light there must be weaker than that of Earth. ”

"Like us humans, their visual receptors also grow on the front of their heads, which means that on their planet, they are also at the top of the food chain and are also predators. Because only predators evolve front-facing light receptors, predators will evolve light receptors to the sides of their heads out of the need to avoid predators. ”

"Its eyes are always open...... Not. I noticed that they don't seem to have eyelid structure, which means their eyes can't be closed. It can be inferred that in the early stages of their evolution, their ability to perceive light must have been very important, and the need to survive required them to retain their ability to perceive light at all times, even when they were resting. This means that in the early stages of the evolution of this race, their living environment must have been very harsh. They must have to face many crises, which is why they have evolved organs that can feel the changes of light even when they are resting. ”

"Leaves fall. You see, they also have human ear-like organs on either side of their head, which I think should be their sound receptors. Sound is airborne, which means they also live on a planet with an atmosphere. Well, this is also evidenced by the fact that this is suspected to be a respiratory organ, which means that their survival also depends on the exchange of gases between the planet's atmosphere. As for what is the composition of the atmosphere of the planet they live on. It is unknown exactly what kind of gas they need to survive, but will need to be further anatomically analyzed. ”

"Is this opening on the underside of the head a mouth? Since they have sound receptors, we can speculate that there is a high probability that they also rely on sound vibrations to transmit communication information in daily life. There is a high probability that this life will make a sound through this opening. ”

"There's something suspicious of scales on top of its body, and I think it may have evolved to keep it warm. Through the analysis of their eyes, we have come to the conclusion that their living environment has weaker light than the earth, and weak light intensity usually means less heat and lower temperature, so the evolution of scales can be explained. Life on Earth evolved hair to keep warm, and this life evolved scales. As for why this difference occurs, it may be due to the difference between the environment in which they live and the planet. Chances are, on their planet, scales are a more suitable way to survive than hair. It is impossible to speculate as to what exactly this difference is. ”

"You see, these creatures have big heads, but relatively weak torsos, which means that their planetary gravity is much smaller than that of Earth. There is the following data that allows us to estimate that the ratio of our human torso to head is about nine to one, and this kind of life form is ......" Wei Feng glanced up and down at the alien's body in the hibernation module, and then said: "The ratio of their torso to head is about three to five to four .5 to one, which means ...... The gravity of the planet they live on is about 35 to 50 percent of the gravity of the Earth. While it is impossible to determine the size and mass of their planets, it is certain that both must be smaller than Earth. ”

The appearance of life forms that evolve in the universe, especially intelligent life forms, will inevitably follow certain rules, for example, life forms that evolve on planets close to stars will inevitably evolve light receptors. Because in a well-lit situation, being able to feel the light is a great advantage. And since those who can feel light will have advantages, and those who can't feel light will have disadvantages, according to the theory of evolution, then advanced life forms will inevitably evolve towards the path of being able to feel light.

The same goes for the proportions of the torso and head. Intelligent life is known for its wisdom and not physical strength, so it would be a waste to evolve an overly powerful torso in a low-gravity environment, and in that environment, it would be advantageous for a torso to be weak. So this advantage will also be preserved.

Similarly, if there is an atmosphere, then advanced life could almost certainly evolve hearing and vocal organs. Because in the atmosphere environment, the hearing and vocal organs have great convenience. Conversely, if a life organism were born in a vacuum, or on a planet without an atmosphere, it would not have evolved hearing and vocal organs. If a sapient life had been born underground or far from the stars, it would not have evolved the eyes, which are light receptors.

It can be seen that if there is another planet in the universe that is very similar to the Earth's environment, then the intelligent life that has evolved on that planet must not be much different from that of human beings. Because this is a process of natural selection, the fact that human beings have survived and reproduced so far has proved that the current body structure of human beings is the optimal solution and the most suitable for today's environment. Since this is the optimal solution, then on another earth, the organisms that deviate too much from the optimal solution and are guided by the development direction of intelligence will be eliminated by the natural environment in the early stage of evolution, and they will not have the opportunity to develop to have advanced technology.

It is precisely because of these prerequisites that Wei Feng can infer so many things through the appearance of this alien.

But...... Even after surmising so many things, Wei Feng still didn't know the ins and outs of this alien at all. The universe is too big, there are too many stars, and there are too many planets that may meet the above planetary indicators. Wei Feng couldn't be sure which galaxy they came from.

"Captain......" Ye Luo said faintly at this time, "Indeed, as you said, if there is no additional source of intelligence, we can only speculate about the approximate living environment of this extraterrestrial intelligent life, but we cannot determine which planet they come from and which star system they come from. But...... I don't know if you notice that one of the planets we've observed fits exactly the metrics you speculated above? ”

"Oh?" Hearing Ye Luo's words, Wei Feng immediately became interested in his heart, and asked, "Has we already observed it?" Which star system is the planet? How far is it from us? We have already speculated through materials science that the alien civilization is not too technological, and if the planet you are talking about is not too far away, then that planet is most likely where they were born. ”

"This planet is very close to us." Ye Luo continued to say in an inexplicable tone, "It was one of the first planets we ever explored. It's even right in our solar system, next to our Earth. ”

Wei Feng was stunned for a moment, and then reacted, and a feeling of extreme shock and absurdity immediately surged in his heart: "You mean...... Mars?! How could it be Mars? How can it be? ”

"Is there something wrong?" Ye Luo said, "Look...... It has plenty of light but the light is weaker than the Earth, it has an atmosphere, the temperature is lower than the Earth, and the gravity is only 35 to 50 percent of the Earth's...... Which of the four indicators you proposed does not meet on Mars? ”

Wei Feng squatted on the ground again, only to feel bitter in his mouth, and he couldn't say a word. (To be continued......)
