What if our body continues evolving?

    

What if our body continues evolving? 

The fact is that evolution continues in our body, and we still need adaptation to the changing environment. And one of the examples of that advantage of advance is the third artery in the hands(1), which will transfer blood to the fingers, and that thing makes the use of the keyboard easier. The movement tracks of the fingers when we are using keyboards are small, but the movements will create lactic acid, and the muscles of the fingers need the nutrient and oxygen for their operations, as well as other muscles, need those things. 

The reason why the evolution in the human body continues is that the environment is changing. But also the genetic structures in our bodies are changing because retroviruses are connecting new genetic material in our DNA. 

But also the natural background radiation is causing changes in the DNA. The background radiation along with chemical stress causes oscillation in that molecule, which sometimes breaks the structure of the double helix of that molecule. 

The evolvement of us causes interesting theories about what we might look like somewhere in the future. The fact is that the use of technical equipment like computers is causing changes in our nervous system, and if we would move to space and build colonies on other planets in the future, that thing causes that the bodies and nervous systems of the colonists will adapt to the environment of that planet. 

Are "aliens" and UFOs the humans and their craft from the future? 

The thing, that makes space colonies an interesting topic to think about in the case of evolution is that those colonists who will leave at first to Mars but then farther would be the most capable people of Earth. And that means that the advancement of evolution would be fast, and that thing has been a theory that maybe humanoids are humans from the future. 

The adaptation that continues in generations can cause that the people who are living in stable colonies around the solar system are turning to their species. This advancement is unstoppable if the journeys between colonies and the Earth will take years. And even the journey would take only months or weeks, sooner or later there will be born people in those colonies, who are thinking that those colonies are their home. 

They ever visit Earth, and evolution will take the next step. In history, the first colonists of America returned home, but then somebody wanted to stay in the new world, and maybe history is repeating itself also in the cases of space colonies. 

And if that thing would not happen to the colonies, what might rise to solar systems of other stars will cause that the human race would turn to new species. The journeys to other solar systems will be one-way trips, and the descendants of the leavers are not even known what the Earth is.
