Scientists tell what people will look like in a million years.

Will people change into semibiological and half artificial hybrids?

Or will we grow longer or shorter, smaller or thicker, or even new features of our face and body color?

Of course, we don't know that, but to analyze this question, let's go back in time, about a million years ago, to see what people looked like back then.

For starters, Homo sapiens did not exist.

A million years ago, there were probably several kinds of people, including Homo heidelbergensis, who resembled Homo erectus and modern humans, but a more primitive anatomy than Neanderthals.

But in the earliest history, over the last 10,000 years, there have been considerable changes that people have to adapt to. Living with agriculture and food in abundance has resulted in health problems that we have been forced to use science to solve, such as dealing with insulin diabetes. In terms of appearance, people have become healthier and in some areas longer.

Perhaps we will evolve by becoming smaller so that our body needs less energy”, suggests, Thomas Mailund, associate professor of bioinformatics at “arhus” University, Denmark.

This would be useful on a very populated planet”, he points out.

On a planet full of people, remembering people's names would be a very important element. Technology is at stake in this regard.

A brain device would enable us to recall people's names. This looks like fantasy. But we're actually able to do this. Actually, we can put a device into the brain, but we still do not know how to tie it to be useful. We're getting closer, but right now it's just experimental”, Thomas says.

We've all heard of predetermined babies. Scientists now have the technology to change the genes of an embryo despite much criticism, and at the moment no one is sure of what will happen next. But in the future, Mailund suggests that it may be considered ethical that some genes do not change it. With this, we may have the appearance of a baby - perhaps people will look the way their parents do.

With advances in genetics, scientists are increasingly understanding genetic changes and how these occur in the human population.

Normally it cannot be accurately predicted how genetic variations will change, but bioinformatics sector scientists are analyzing demographic trends to give us an idea.

Hodgson, predicts that “urban and rural people will be very different. Migration from rural areas to cities causes genetic diversity to increase in cities and to fall in rural areas”.

Moreover, some groups reproduce more and fewer. Populations in Africa, for example, but expand rapidly so these genes are growing at a high global frequency. While areas where skin color is lighter but reproduce more slowly. As a result, skin color from a global perspective will become darker.

“expects that the average person several generations later will have the darkest skin color from now”, says Hodgson.

What about space? If people can colonize Mars, how will we evolve? With lower gravity, our body muscles can change structure. Maybe we'll have long hands and feet.

In a cold climate, similar to the ice age, we may even become smaller, with our body covered by insulating hair, like our ancestors of Neanderthals.

We don't know, but, of course, human genetic variation but it grows. Worldwide, each year there are nearly two new changes for each of the 3.5 billion chromosome pairs of the human genome”, says Hodgson.

This is extraordinary and probably impossible that after a million years we will look the same.
