Question: do you think we could look like grey aliens in the future? we will have machines to do our phisical work so we wont need muscles and will get smaller and skinier. our yes brains will get bigger because we willl get smarter. our eyes will get bigger because we will need them to work with technologie

  There are lots of different shapes and sizes of animals alive in the world today and even more different creatures that have existed before us! It is very difficult to predict what we might become but you are right, our environment is changing with more and more technology and humans need to adapt just like every other species. Technology has changed our environment very very fast in our lifetimes, but we have changed relatively little in the last 200,000 years that humans have existed. Evolution and adaptation is a very slow process, we are more likely to have to adapt our technology to suit us in the mean time. This is one of our strengths, being able to adapt quickly using intelligence and invention.
  
  Scientists can’t ever agree amougst themsleves on whether a bigger brain means more intelligence, maybe more small brain cells is better than large brain cells, it is a very tricky question that I don’t know the answer to! You are right though over long periods of time the features that best suit us to our environment will become more common and we will very very slowly change into something else!

  Rebecca is right. The life on this planet now shows how all organisms have evolved over millions of years so yes anything is possible. However because things happen so slowly compared to our perception of time in real terms we won’t change significantly for 1000’s possibly 100, 000’s even 1,000,000’s of years!

  Hi @kuth,
  
  As Rebecca and Dave has said above, evolution takes many generations to start producing adaptations as noticeable as you’ve described in your question.
  
  Natural selection and evolution as a whole is blind, it cannot see where it is going and will always try to take the quickest and easiest route. Only those with randomly occurring favorable characteristics that help them survive in their habitat will be able to have a chance at passing on their genes to their offspring; natural selection randomly selects individuals with a survival advantage.
  Loosing muscle mass, shrinking, getting bigger brains, and bigger eyes to work technology don’t necessarily bring an advantage to being able to survive and procreate. That said, we may one day decide that only the smartest should be able to have children or something similar; not that I agree with this idea- there’s a lot of this both in sci-fi and also examples of this in our own history unfortunately.

  I think everyone has covered this really well and I agree with them – we will adapt and evolve but who knows how or when! There are so many of us and we are all so different it could take something huge to ever force our evolution enough that we would ever become different species.
  
  As Rebecca said, our current evolution is incredibly slow. It is really interesting to go to ancient ruins and see how small their beds were back then as they were comparatively shorter than we are now. Our skull shape has also evolved more quickly than our teeth hence why they are too big for our mouths now and many people have to get braces to straighten them out.
