Chapter 135 Convergent Evolution
According to the simulated evolution of the life evolution simulator, starting from the ancient sea of ​​Mars 29 billion years ago, the life evolution tree of Mars based on Martian protobacteria is highly similar to the life evolution tree of Blue Star.

On Mars, plants like algae, mosses, ferns, gymnosperms, and quilts will also evolve...

In terms of animals, similar coelenterates, linear animals, ring animals, molluscs, arthropods, fish, amphibians, reptiles, birds and mammals will also evolve...

However, this similarity is actually only similar in appearance, and its evolutionary process and biological details are actually very different.

In biology, this is called convergent evolution.

For example, although fish and whales look similar in appearance, their evolutionary process is completely different. The ancestor of whales has landed on land, so it evolved lungs.

Even if it returns to the ocean again, in order to adapt to the environment, it has re-evolved a fish-like streamlined body, but its internal structure is actually completely different from that of fish. It still breathes with lungs, not like fish Breathe with gills, and have no fish scales...

Another example is pterosaurs, birds, and bats. In order to fly, they all evolved similar wings, and their appearances are somewhat similar, but in fact, the evolution process and body functions are completely different, and the performance of wings is also different. the difference.

The evolution of life on Mars and the evolution of life on the blue star have produced a large number of similar creatures, which is actually a kind of convergent evolution.

The same carbon-based life, also originated from the ocean, and planets have similar characteristics.

Under these three basic premises, the convergent evolution of life evolution may be inevitable.

Only a fish-like body can survive in the fluid ocean most easily, only a bird-like body can fly in the atmosphere, and only a quadruped can be stable and flexible on land.

Of course, there must be exceptions.

For example, in the deduction of life evolution on Mars, a strange wheel animal appeared...

After its ancestors crawled out of the ancient sea of ​​Mars, they did not evolve into a quadruped state, but evolved into three wheels...

Because the wheels could not be used on more rugged terrain, they have always been limited to plain areas, and later became extinct due to environmental changes.

There is also a type of ship-shaped creature, which can inhale air and become a hovercraft-like existence, floating on the sea surface, so as to better swallow algae on the sea surface, and when flying creatures appear, they become extinct...

This also confirms the inevitability of convergent evolution to a certain extent. Those strange creatures will all become extinct because they are not suitable or have major defects. Only these forms that have been carefully selected on the blue star are the final choice of nature. ...

At the same time, He Xiao also discovered that almost all evolved creatures on Mars have the ability to dehydrate, and their lifespan is much longer than that of Blue Star.

This shows that Mars has a harsher and more extreme environment than Blue Star, and dehydration and longevity seem to be the necessary conditions for evolution. Without these two characteristics, it is impossible for life on Mars to continue.

Another point is that it may be because the gravitational force of Mars is only one-third that of the blue star, so the largest terrestrial life evolved on Mars is much larger than the blue star.

……

He Xiao used entries to test and found that most of the fossils of these creatures had a difficulty of more than 1 million readers. This shows that in the real history of Mars, these creatures did not exist and were not really evolved.

There are only some low-level plants and animals, and the difficulty is less than 1000 million readers.

This shows that they may be real, at least similar creatures have appeared...

It can be seen that life did appear on Mars and evolved to a certain extent, but the progress of evolution was very low, only reaching the level of moss and linear animals on the blue star...

What He Xiao has to do is to use the entries to change the history of Mars, "resurrect" these evolved Martian creatures, and use them as a basis to create higher-level life on Mars.

In doing so, on the one hand, it will allow humans to have a deeper understanding of the evolution of life and promote human biology and life sciences. On the other hand, it will also provide great convenience for humans to colonize Mars.

Since they are all carbon-based life forms with amino acids and proteins, they should be food for Mars immigrants...

If several kinds of large animals are evolved, it is also good to be domesticated livestock, such as the wheel animals. If they are revived, there is no need to build cars. Wheels are much more energy-efficient than quadrupeds.

It doesn't matter what the terrain is, humans can build roads!

Even intelligent creatures are not out of consideration, as long as they can ensure that they do not threaten humans, it is also possible to create them to help human immigrants...

Moreover, they can increase the number of readers!

The number of people on Blue Star is limited. Even if he uses entries to modify it, the efficiency is still too low. After all, everyone has an idea of ​​how many people there are on Blue Star. If you secretly increase too much at once, it will definitely arouse suspicion.

But it might be different on Mars, and the reproductive ability of Martian intelligent organisms can be set in the later stage. If they have a strong reproductive ability, they can grow on a large scale in a short period of time...

Don't worry too much about their threats, as long as they don't have the ability to leave Mars.

I couldn't control it anymore, and a bigger space rock than the previous one fell down, and it was over.

If one doesn't work, then a few more...

Of course, this is only the most extreme situation. Under normal circumstances, He Xiao would not use entries to do this kind of thing. He is reluctant to destroy the world he finally created.

Just do it, He Xiao started his Mars Creation Project. At the beginning, he must start with the easiest one.

He edited a new entry:

【Mars Giant Moss Fossil】

"On January 2030, 1, the Duke VIII rover on Hawk Island made another major discovery near the North Sea of ​​Mars. According to the research and analysis of the Hawk Island Academy of Sciences, this is a moss-like fossil of Martian paleontology. For a long time, They are all frozen in the ice layer of the North Pole of Mars. Due to the recent sharp rise in the temperature of Mars, the ice layer of the North Pole has melted, and it has also followed the melted water flow to the low-lying area...Because the life on Mars has the ability to 'sleep', Hawke The scientists of the island think that it may be revived..."

This entry is actually a completely real entry, whether it is a text description or a picture, it is all real.

Since the number of readers required is 0, the task is not triggered.

However, the discovery of this moss fossil was not a coincidence, but He Xiao used the specific longitude and latitude tested by the entry, and then personally controlled a Duke [-] Mars rover, and "accidentally" discovered it.
