Charles Darwin and the future You.
A lot of people at the time, and ever since, have disagreed with this theory. However, others believe that it is a possibility that humans, and other species for that matter, can evolve in time to adapt with its new environment and to protect itself. That is not to say that the species has evolved into something else, but it has changed into a new version of itself.
Let me explain. In Northern England there was a particular species of moth which was white. As Northern England was industrialised in Victorian times and factories and homes burnt coal more and more buildings became darker in appearance as the coal dust from the smoke settled on brickworks and generally everywhere. In time, that particular kind of moth bred a new offspring which was darker in colour to enable it to camouflage from its prey. So a different species evolved; but in essence it was the same moth which changed colour through the generations. When eventually Britain stopped burning coal as a fuel and new buildings were put up, (or the old ones cleaned), through various generations that moth changed back to its original colour.
The same argument can be made for the human species. As time goes by we "evolve" or adapt to survive our various environments. There is evidence for instance that in the Middle Ages people were much smaller and shorter than they are now. This is seen from the size of doorways in castles, and from bones found in graves. But as time went by and diets improved, as well as health standards, today's people are much bigger and stronger compared to their Middle Ages counterpart.
All this was explained by Darwin in his book On the Origin of the Spices where he explains where different spices come from and how they can improve different types of foods and cuisines.
Charles Darwin also spent some time in the Galapolos Islands where large tortoises live. He observed that on islands with humid conditions the tortoises are larger with domed shells and short necks. On dry islands however the tortoises are smaller with longer necks. He also discovered the very first claustrophobic tortoises which would not go into their shells because they were afraid of the dark. Conversely, in another island he discovered other tortoises which would not come out of their shells because they were afraid of open spaces, (agoraphobic), and also because they were dead!
Following Darwin's theory of evolution to its inevitable conclusion, some scientists today believe that humans will continue to evolve in order to adapt to our ever changing environment and living conditions. For example, modern man has no use whatsoever for toe nails, (except for those who collect them as a hobby), and it is feasible that future generations will grow without toe nails.
As we get busier and busier in an ever faster world a second mouth would come in handy. We could use one mouth for talking, or answering the phone, and another for eating our lunch. This way we don't need to have a lunch break and we would work for longer and be more productive.
Personally, I'd like a mouth on top of my head. This way I could put a sandwich under my hat and eat it whilst going to work.
It would also be a good idea to have an extra eye. Say at the end of your index finger. This way you could clean your ear and see what's inside at the same time.
You know how you sometimes wish you had an extra pair of hands? Scientists believe that this may well happen in future with humans having two pairs of hands both coming from the side like now. This way I could drive the car and scratch my bottom at the same time.
Being very attentive and able to listen to all messages that the world throws at us simultaneously would mean that in future we would grow an extra ear growing out of our forehead. This would be known as the Final Frontier.
Evolution would not of course just be limited to humans. Scientists could grow a turkey with 12 legs so we can have one each on Thanksgiving and Christmas. Problem is ... he'd run too fast and we won't be able to catch it. Scrap that idea!
Can you think of any evolutionary ideas which would benefit us in the future? Don't be shy now ... let your imagination run wild and share your thoughts with us.
