What will humans look like in a million years?

Since the beginning of the earth millions of years ago, humans are also in constant evolution, so what will humans look like a million years from now? First, to understand our future evolutionary direction, we need to review the evolutionary history of humans.
will our offspring be implanted into high-tech machines, growing renewable limbs, and using eye cameras to gather information about their surroundings, as described in science fiction? Could humans become a hybrid of living and man-made machines? Or will we become smaller or taller, thinner or fatter, and even have different facial features and skin tones? Of course we don't know.
but with that in mind, let's go back a million years and see what humans were like at that time. first,
, Homo sapiens did not exist a million years ago, and there may be different human species on Earth, such as Homo Heidelbergensis, which bears many similarities with Homo erectus and modern humans, but more primitive than later Neanderthals.
we're moving closer to a time when we're moving forward.
In the past ten thousand years, human beings have changed a lot in adapting to the environment.
the popularity of agriculture and the abundance of food have led us to use scientific methods to address health problems, such as insulin treatment for diabetes.
from the physical appearance, humans have become fatter, and in some areas they have become taller. 'Maybe in the future we'll evolve smaller bodies so that our bodies need less energy, ' says Thomas Mailund, an associate professor of bioinformatics at Aarhus University in Denmark,
.
living with many people is a new situation that human beings must adapt to.
When we were hunter-gatherers, we interacted with others every day.
believes that in the future we may be able to help solve this problem in some way.
for example, remembering someone else's name may become a more important skill.
this is where technology comes in.
"Implants in the brain allow us to remember other people's names," says Mellon.
we may change all that in the future.
it sounds like science fiction, but we can do it now."
we can implant devices in the brain, but we don't know how to connect them to make them work.
we've made some progress, but at the moment these are experiments. "It's no longer a biological issue, it's a technical issue," he said.

, people can now use implants to repair damaged parts of the body, such as pacemakers or hip implants.
perhaps in the future, implants will only be used to improve human function.
in addition to brain implants, we also have a lot of technical implants on our appearance, such as artificial eyes with cameras that recognize different colors and visual effects.
we've all heard of custom babies.
scientists already have the technology to alter the genes of embryos.
Despite the controversial technology, no one is sure what will happen next.
but in the future, Mellond believes that not changing certain genes may be considered immoral.
there may be a lot of choices about baby characteristics in the future, so maybe humans look just as much as their parents want.
", "It's still a choice, but it's just a manual choice."
What we do to dogs now is what we will do to humans in the future," Mr Mellende said.
this is all-of-a-kind assumptions, can demographic trends give us an idea of what the future of humans will look like? "It's pure speculation to predict what will happen a million years from now, but it's certainly possible to predict the near-term future through bioinformatics combined with currentknown genetic variations and future demographic models," said University lecturer Jason J. Dr. Jason A. Hodgson focuses on ecosystems and environmental issues.
Now we have genetic samples of complete human genomes from all over the world, and geneticists are delving into genetic variation and its structure in the human population.
we can't predict exactly how genetic variation will change, but scientists in bioinformatics are looking for clues from demographic trends.
Hodgson predicts that the demographic divide between urban and rural areas will grow.
"All migration comes from rural areas, so genetic diversity increases in urban areas and less geneticintraits in rural areas," he said.
" will vary around the world, but in the UK there is less diversity in rural areas and a lineage has existed for longer.
and urban areas have more genetic diversity. some groups
have higher or lower rates of reproduction.
for example, Africa's population is expanding rapidly, so these genes are growing more frequently at the global population level.
rates are lower for light-skinned people.
, as a result, Hodgson predicts that from a global perspective, the skin colour of humans will get darker and darker.
"It's almost certain that the frequency of black skin around the world, relative to light skin, will increase," he said.
" space? If humans did eventually colonize Mars, what would we have evolved into? As gravity decreases, the muscle structure of our bodies changes.
maybe we'll have longer arms and legs.
in a colder glacial climate, we'll even become fat with insulated body hair, like our close relativeNeander.
we don't know, but there's no doubt that human genetic variation is on the rise. 'Looking at the world, two new mutations occur each year out of the 3.5 billion base pairs in the human genome, ' says
Hodgson.
it's amazing - it makes it unlikely that humans in a million years will look the same as we do now. related
: How far will humans evolve in the next million years? What will happen to us as humans in the next million years? This question may seem out of reach, but it is certainly interesting to imagine the future of mankind.
first of all, we all know that we humans have evolved to this extent over five million years, but in the last few thousand years of human history, it seems that humans have not evolved anything, is it because evolution is wrong? In fact, with the discovery of genetic engineering, in fact, we have long since gone through the natural evolutionary forces, because the evolutionary factor is the survival of the fittest, when we humans evolved to Homo sapiens, can already be called the master of the earth, so do not need to evolve for environmental reasons.
today's humans have learned to do more than just adapt to the environment, we can now change the environment, not the environment to change us.
But in the future we can change our own genome, by specific intentional modifications to change ourselves to eliminate some unwanted traits, although it is difficult, but not impossible, to change genes, because now the technology is already on that step.
once we start to change our own genomes, we are basically out of the limits of evolution because we can make the changes we need directly to ourselves.
so in the next million years, if you don't accept technology to change itself, humanity will be no different from what we are now.
but their bodies may be more perfect than ours.
