Every mutation is not favorable.

Every mutation is not favorable. 

Sometimes philosophers have thought what the creature like the small population of the human race would advance only one thing in the body, and that thing would be level of intelligence. Would the result of this thing some kind of space civilization, which cannot even land on the planets, because their body would turn too weak.

We can think that if we would sit on the chair and look at some screen, that would increase our level of intelligence because that is making possible to deliver nutrient to brains and make more connections between the Neurons. But in real life, the thing is not like that.

Every nutrient bite, what is released when we are sitting doesn't go to advance our brains. And this kind of thing is dangerous for people. If we want to improve our ability to process the data, we must create connections between neurons, and at the same time create more neurons, which is connected to other neurons.

So in this case, we should create bigger brains with more neurons and connections. But that thing is not enough. We would need the useful data, what to process in those super brains. Because if we would not have any data to process, our brains would be useless, if there is nothing to do with them. Without data, our brains would be the only thing, what takes nutrient from the body.

Why natural selection has started to favor intelligent individuals in the human race? Why that advantage has not happened with other species?

And if we are thinking about natural selection, there must be something that causes that the selection would start to favor the individuals, which is highly intelligent. That selection has caused our brain capacity has started to advance.

The idea of mutations is one of the key elements in the thing, what we are calling as the Evolution theory. The thing is that the mutation is not always favorable, and that means that when the species would advance that requires billions of the transformations of the sequences and order of the bases of the DNA, and as I have said every change in that order is not favorable.

So when the species is advancing there is billions of possibilities, that some mutation is favorable. And when we are thinking about intelligent capacities, there are many other things, what we should advance because if we would increase only the intelligent capacities of the population, that would cause the creation of the classic "humanoid" or "intelligent creature". That creature would have weak muscles and a big head.

But what happens if that creature would live on the Earth. The highly orientated creation of the advancing of brains would cause the rest of the body would be too weak, to carry the creature. And that's why this thing would not work on Earth.

So where this kind of creature could live. The answer is the zero-gravity environment. In those fully controlled conditions, there is a possibility that the creature would transform into a thing, that has only weak muscles and big brains left. But this kind of thing is I hope, hypothetical way to think.
