The Future of Man--How Will Evolution Change Humans?
Human have not stop evolving. Although civilization has not been around long enough to see any extraordinary changes , we can nonetheless expect to see some as time drawn out.
Let us begin this hasty preview by focusing our eyes on a distance of say 5,00,000 years and 10,00,000.
My real reason for not limiting our vision to 1,000 or 10,000 or even 50,000 years hence is that it would be rather difficult in the hasty glimpse, which are about to take, to find much in the way of interesting differences. For man does not change very rapidly, and we must allow him sufficient time to undergo a few modifications.
CHANGES IN THE SIZE OF BRAIN
The brain is most important part of the body. It is the software storage of our body. For 2 million years the brain evolved when our ancestors were changing from apes to humans. then this evolution of brain stopped and since then there is not much difference in our body parts.
But i am sure if conditions changes then to keep pace with the world our brain will again evolve to a greater size.
In the past it happened so why not again in the future? Remember
"HISTORY REPEATS ITSELF"
CHANGES IN HEIGHT
In future there will be change of height also because there is no use of height. A simple example is that in future our all work is done by the machines and that’s why we can lose our growth hormones and our height become decreasing in the future 10,00,000 years.
CHANGES IN MUSCLES
It is clear that in future our work will done by the machines or the robots that we have made and that’s why we will lose our hormones and our muscles become thinner and weaker.
CHANGES IN EYES
Our eyes will modify to protect themselves from Harmful rays of the sun. The eyebrows & eyelashes will vanish because there is no need of them in future.
CHANGES IN HAND
In future we may have small hand with only four fingers. We may lose our smallest figure as we can see that its size is gradually decreasing.
CHANGES IN HAIR
In future it is clear that there will be no hair on human body as we know there is no use of it. We have less hair than our ancestors and we are gradually losing our hair as we don’t need them.
CHANGES IN EAR
Today we have our outer ear but in future we may lost it because from earlier 1000 years we have lost the ability to move our outer ear forward & backward and that’s why in future1000 year we may lost our outer ear.
CHANGES IN TEETHES
Dental Modifications But this is not the whole story of the degeneration of the human dentition. In still other ways it manifests itself. I shall mention only two more. One is the increasing suppression of the third molars or wisdom teeth. Not only is the age at which is normally erupts, 18 to 20, being pushed back later and later in life, but in many people they are absent in whole or in part. The second is the constriction of the jaws. It is obvious that the crowding of the teeth and the constriction of the jaws may be associated, but not always is this case.
Weakening Teeth One cannot help being convinced that all this evidence is symptomatic of a fundamental process which may in time be responsible for considerable alterations to our dental equipment. I do not propose to enunciate a dogmatic generalization to account for this situation. Controversies on the nature and cure of dental decay have flourished for generations among those interested in teeth. Decay has been attributed to hyperacidity, to endocrine dysfunction and to diet, among other factors. No doubt the situation is a complex one and the superficial causes may be as varied as the manifestations they produce. But one cannot but be impressed by the fact that the dentition is an area of weakness. My guess is that the teeth are, to a large extent, losing their function and consequently
