As space will change humanity in the future?

What do you think, will people ever leave the Earth? And if we succeed, will we be able to find their place in the vast cosmic ocean? Environment out there beyond our home planet, is very different from that in which we evolved over millions of years. For this reason, it is not excluded that our species will be quite different. At least it was in the writings of many authors of science fiction, such as Robert Heinlein in «the moon is a harsh mistress» when, in the absence of gravity humans evolved in the unnaturally tall creatures with brittle bones. While the specific outcomes and ways are quite different in science fiction, the very concept of the metamorphosis of man away from Earth – not so far-fetched. Yes, it may seem that it is not, but people still evolyutsioniruet. So according to Scott Solomon, the evolutionary biologist Dr from rice University, the relocation from the Ground will inevitably change us. But the speed with which this will occur and how the future era of space travel will change humanity?

Evolution of man in space

In fact, even a temporary stay in weightlessness is already changing us. Remember the famous study of two astronauts-the twins Scott and Mark Kelly? One of them had been on Board for almost a year, while the second was on the Ground. Upon return of Scott to the ISS was in his body, much has changed, down to the bacteria in the intestine. Read more about this exciting experiment . Moreover, the astronauts even after several months of stay in space can take years to recover the body after exposure to microgravity.

The changes that occur over time in microgravity is loss of bone density; without the constant stress that gravity puts on your bones, they lose density is about 10 times faster than it does osteoporosis – a disease in which bones leaches calcium, causing them to become brittle. There are also anatomical changes in the eyes, microstructural changes in the brain and even changes in the microbiome of the intestine. While all of these physiological changes give us some idea of the impact on the evolution of Homo Sapiens has a environment, these changes affect only certain people (the astronauts), which, it seems, soon after his return to Earth everything goes back to normal, even if takes a few years.

If we can conquer space, then a series of evolutionary changes is inevitable.

However, from the point of view of the evolution of these changes but only a moment. But not only the environment determines the future path of human evolution. Culture – the way we live and the choices we make – also plays a role in the conquest of space and can speed up development. Thus culture, technology, and natural selection will influence the course of human evolution that will conquer space. But what we can become? Science fiction argues that the lack of gravity will inevitably result in people with brittle bones, but scientists think otherwise – that the greatest changes in bone exerts tension during childbirth. Moreover, the process of birth difficult, and minerals for child's growth was often taken from the bones of the mother, which inevitably leads to a decrease in bone density. Thus, women are more likely to survive pregnancy and childbirth in space and, possibly, will have more dense bones that allow them to produce healthy offspring.

However, it should be noted that if in the near future we will not solve the problem of space radiation – effect which has a detrimental effect on the state of the whole organism, but also destroys the brain, neither of which colonization of other planets may not be considered. I would say that today this is the main problem that separates us from the opportunity to travel at least within the Solar system. In addition, we may not consider all the factors that can have an effect on the evolution of man, for the reason that we don't know what factors will come into play and which are not.

What is the founder effect?

it is possible that the planet Earth is our only home.

Even with all of these random decisions before these pioneers went to the infinite to the finite, the border — the decisions we could see in our lives, in fact-will have a greater impact than we can know. As explained by Solomon, this is another effect that we have seen on Earth — the founder effect. The people who are the founders will have significant influence on the long-term composition of the human population in space. This is not surprising, since in space sent people with higher education and in good physical shape.

But do not forget that not every country has the resources to implement the space programme or training astronauts. Sometimes the decision about who will go into space, can be politically motivated. Besides,people can select on the basis of the physical characteristics of that sound , especially when it's about the journey, in the course of which may be replaced by several generations. It turns out, much of what how we develop and what we develop depends not only on the presence or absence of gravity, but from those whom we send into space.
