Evolution is a very intriguing and interesting concept. Most of the animals, plants and insectlife that we see around us today have evolved over millions of years. Species, be it animallife or plantlife, evolve to adapt to their evironment. Now the word environment includes a whole host of things. Availabilty of food, climatic conditions, competion for food and so on and so forth. Most of the species that we see today are very different from what they were millions of years ago. The best example for the evolutionary process can be that of the giraffe. This animal, found in the plains of central and north Africa did not have the long neck which is its most identifiable characteristic. Millions of years ago, the giraffe looked like today's horse or the zebra sans the stripes. But over a period of time when food became scarce these animals were forced to strech their necks in order to reach the leaves on the trees at a higher level. This resulted in what Darwin(yes! the father of evolution ,himself) called as 'The Genetic Drift'. i.e.the transfer of genes from one generation to another.Species tend to display physical characteristics in order to better adapt to their environment. I picked the example of the giraffe to explain this thesis for a specific purpose. 

Man [yes, you and me(?)] is the only species which has shown so much evolutionary changes in so little a time. It all began way back and i mean way back! Over three million years back to be precise. When a certain group of primates (present day Gorillas,chimps,monkeys and us included ) climbed down from the trees and began forraging for food. Over a period of time they began to use two limbs instead of four and the brain began to develop. With which of course came knowledge, early man(Australopithecus) began using tools. Physical traits such as strong forearms and legs and loss of much  body hair began to show. Over a period of time we developed i.e physically in to what we are today. 

Here is where my point begins. The theory of evolution is replete with instances of species evolving into totally different beings. Now if that is the case will we evolve into something else in say ten thousand years? I think so.  

Man has generally evolved to better adapt to his environment. Since food was a primary reason for survival he learnt to use his hands and made tools. Over a period of time when we began to metamorph into inteligent beings our brains have also been growing and I mean literally. Now we have reached a stage when the brain is the most important organ in our body. In other words everything that we need or require is taken care of by the brain. With the advent of the Information Revolution of the 1990's an alarming concept has come up. If this continues at this pace pretty soon we will not have to exert any physical pressure on our bodies for anything. Everything will either be done by robots or by computers. However since a computer or robot is essentially controlled by the brain, it will show considerable changes. One for example would be the increase in its size. since the amount of calculations and other procedures increase so will the physical size. In other words a thousand years from now an average human head will be double or even triple the size it is now. 

Also since we have robots to do everything for us, specific physical attributes such as strong forearms and legs etc. will show significant changes. The average human height will reduce to about four to five feet and our arms will be short,our fingers longer owing to the fact that we need them the most while operating on computers. In other words what I call a' Reverse gentic drift'. The gentic variations will be primarily on the brain and it will continue to develop. Just like the giraffe, only in this case its the opposite. This is what i feel will happen to the human race( homo sapiens) over a period of time-ten thousand years-say.
