At present we are wearing costly cloths, using highly advanced electronic devices, doing so many researches to find out the possibility of human life in other planets. These are only came to possibility from 200 hundred to 100 hundred years of past. The quest for finding new things placed the man unique in animal world. But the evolution of these things happened so fast when compared to the development of man from apes.
The first man journey on this earth started few lacks of years before in the form of ape. Up to now many forms evolved during the development of ape to man. Why these so many forms have evolved and wearied off during the time. The famous scientist Charles Darwin explained these things through his human theory of evolution.
The main things of human theory of evolution are
1. Nature selection
2. Survival of the fittest
But what are these things mean?
The quality of nature is it selects some kind of species from presently existed ones which could survive in its environment. The remaining which are not capable of survival will be deteriorated gradually and lost completely after some time. The only strong and fittest species can only remains for the future.
The same thing happened during the evolution of man also. At first some apes started living in lands leaving their original residence trees.
The apes use their tails for balance during the time of jumps from one tree to another tree. When they started living in fields there is no use for their tail. So during generations the genes remains latent in their genetical structure, so gradually generations to generations the tails was reduced and disappeared.
During the time of their walk its find difficult to walk on four legs and started 2 legs walk. Thus some energy was saved. They started thinking wisely and used the resources that are around them. Every thing was observed so carefully. So the brain used extra energy and improved generations to generations. The long time walk because of vagrant kind of life, running during the time of hunting turned the spinal card from c shape to s shape, that means man becomes straight.
So many mutations in genes have taken place to arrive the human appearance in to present form. At last 7 lack years before the man which is very very near to present man has evolved.
50000 years back some humans invented some kind of communication, thus the first step towards languages has taken place.
These are the main resolutions because of the nature of human body, that is adaptability. For example any Indian have gone abroad some America or any other cold country, and lived for a long time, the body gradually adapts the changes in weathers, like reducing melanin content in skin pigments, storing extra pounds in body to bare the cold and few other things. Even though these changes are minute, it takes a long time to appear.
The very important things in human evolution took so many long years of time to take place.
But in very short period of time the science was developed, at present our life style has completely changed. Many of the people suffering from deceases like diabetics, high blood pressure, cancers, and so many psychological deceases. All these because of the drastical change in life style and food habits. Our body is not adopting these things that much easily because our body is still in the position when we lived like a predators.
The changes are so fast and not giving enough time to our body to adapt those. Because of that we, humans are in great mess for our existence in this super fast changing world.
Already our scientist have declared the male species in humans will be no more after 1,00,000 years. Because the jobs at present giving them a lot of stress and falling in to the deceases so far considered intact effecting their quality of fertility. That means the y chromosome of 23rd gene is weakening gradually. If it continued further we will be no more. That means cloning rules the future.
So beware guys, think about it.
