Earth Era

This is a dark and empty space, and the nearest star is also about a light-year away. Wei Feng has been alone in this vast universe for more than 300 years. Under such circumstances, Wei Feng turned on a device taken from space in the Xinghai spacecraft, and then saw a creature that absolutely did not belong to the known category of any human civilization.

It undoubtedly belongs to the biological category. Wei Feng can even distinguish its thinking organs and torso from its appearance. It was frozen in a pale blue transparent solid, motionless, like an amber. It has a large head and a small torso, and skin covered in what appears to be scales. 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 things that seem to be eyeballs stare at the top quietly. When Wei Feng just came over to check the internal situation, Wei Feng's line of sight happened to meet these eyes.

It is conceivable what a huge impact this will have on Wei Feng. Even if Wei Feng has undergone more than 20 years of professional training and hundreds of years of long-distance voyage training, it will be a bit of a shock. Can not bear. Wei Feng recovered after a few minutes, then stood up again, walked over to the hibernation cabin equipment again, and carefully looked at everything inside.

Ye Luo's voice sounded at this time: "Captain, did this alien die because we cut off the energy supply? This matter requires further analysis to come to a conclusion. This device exists. It's been so long after all, and it most likely died before we found it."

Wei Feng did not respond to this sentence, but was still a careful observer, and said slowly at the same time: "Look, this should be its light receptor, since it can evolve eyes, it shows that the species that gave birth to it is born. That planet must have a lot of light on it, which means that the planet must be near a star. Um. No, its visual receptors are larger than ours, which means that it lives on Although there is light on that planet. But the light intensity there must be weaker than the light intensity on Earth."

"Like us humans, their visual receptors also grow on the front of the head, which means that on their planet, they are also at the top of the food chain and belong to predators. Because only predators have evolved to grow in Frontal photoreceptors. Prey have evolved photoreceptors on the sides of the head to avoid predators.”

"It's eyes are always open...well, I found that they don't seem to have eyelid structures, which means their eyes can't be closed. It can be inferred that at the beginning of their evolution, the ability to perceive light must have been very good. Important, the needs of survival require them to retain the ability to perceive light at all times, even when they are resting. This means that in the early stages of evolution of this species, their living environment must be very harsh. They must face There are many crises, so we have evolved organs that can sense changes in light even when we are resting."

"Yeluo, you see, they also have organs similar to human ears on both sides of their heads, which I think should be their sound receptors. Sound depends on air transmission, which means that they also live in an atmosphere with an atmosphere. On the planet. Well, this suspected respiratory organ also proves this, which means that their survival also depends on the gas exchange with the atmosphere of the planet. As for the composition of the atmosphere of the planet where they live, they Exactly what kind of gas is needed for survival is not known until further anatomical analysis is undertaken."

"Is this opening on the underside of the head a mouth? Since they have sound receptors, we can speculate that they also rely on sound vibrations to communicate information in daily life. Life has a high probability of making sounds through this opening."

"There are suspected scales on its body. I think it may have evolved to keep warm. Through the analysis of their eyes, we have come to the conclusion that the light in their living environment is weaker than that of the earth, and the light intensity Weak usually means less heat and lower temperature, so the evolution of scales can be explained. Earth life evolved hair in order to keep warm, and this life evolved scales. As for why this difference occurs, this Probably because of the difference between their environment and Earth. Most likely, on their planet. Scales are a better way to survive than hair. It's impossible to speculate what the difference is."

"You see, this kind of life has a big head, but a relatively weak torso, which means that their planetary gravity is much smaller than that of the earth. With the following data, we can estimate that the ratio of our human torso to head is roughly Nine to one, and this kind of life form..." Wei Feng glanced up and down the alien's body in the hibernation pod, and then said: "The ratio of their torso to head is about 3.5 to 4.5. Biyi, this means... the gravity of the planet they live on is about 35% to 50% of the earth's gravity. Although it is impossible to determine the size and mass of their planet, it is certain that this Both must be smaller than the Earth."

The appearance of life forms that evolve in the universe, especially intelligent life forms, must follow certain rules. For example, life forms that evolve on planets close to stars must evolve light receptors. Because in the case of sufficient light, the ability to feel the light is a great advantage. And since those who can feel the light will have advantages, and those who cannot feel the light will have disadvantages, according to the theory of evolution, then advanced life forms will inevitably evolve towards the path that can feel the light.

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

Likewise, if there is an atmosphere, then advanced life can almost certainly evolve hearing and vocal organs. Because under the atmospheric environment, the hearing and vocal organs have great convenience. Conversely, if a life form was born in the empty space of the universe, or on a planet without an atmosphere, then they must not have evolved hearing and vocal organs. If a kind of intelligent life was born underground or far from the stars, then they must not have evolved the light receptors such as eyes.

It can be seen from this that if there is another planet in the universe with a very similar environment to the earth, then the intelligent life evolved on that planet must be no different from humans. Because this is a process of natural selection, human beings have survived and reproduced so far, which has proved that the human body structure is the optimal solution and is most suitable for the current environment. Since this is the optimal solution, then on another earth, lifeforms that deviate too much from the optimal solution will be eliminated by the natural environment in the early stage of evolution, and it is impossible for them to develop to the advanced level. technology opportunities.

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

But... even if he speculates so many things, Wei Feng still doesn't know the origin of this alien at all. This universe is too big, there are too many stars, and there may be too many planets that meet the above-mentioned planet indicators. The satellite winds simply cannot determine which galaxy they came from.

"Captain..." Ye Luoluo said faintly at this time, "It is indeed as you said, if there is no additional source of intelligence, we can only speculate on the approximate living environment of this kind of alien intelligent life, but we cannot be sure that they come from Which star system does that planet come from. But... I wonder if you have noticed that among the planets we have observed, there is a planet that completely matches the indicators you speculated above?"

"Oh?" Hearing what Ye Luo said, Wei Feng immediately became interested, and asked, "Has it been observed by us? Which star system planet is it? How far is it from us? We have speculated that the level of technology of this alien civilization is not too high through materials science. If the planet you are talking about is not too far away from us, then that planet is likely to be their birthplace. "

"This planet is very close to us." Ye Luo continued to say in an inexplicable tone, "It is one of the earliest planets we have detected. It is even in our solar system, next to our earth. ."

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

"What's wrong?" Ye Luo said, "Look...it has plenty of light but weaker than Earth, has an atmosphere, lower temperature than Earth, and gravity is only 35% to 50% of Earth's... Which of the four indicators you put forward does Mars do not meet?"

Wei Feng squatted on the ground again, feeling bitter in his mouth, unable to say a word. (To be continued.)
