Starting from simple organic molecules, thorough the complex process of
Evolution, man has appeared on this planet in the
course of about 2 billion years or so. Life can be on this planet for another billion years at least. In this long period how will
evolution shape out? After say, a million years will there be man as we know him today? We do not know.
Well, we know that various
species have evolved from their ancestors. Many of the original species have become extinct in the process. Through natural selection and by adapting to the environment, changes keep happening in every species. In the course of millions of years the differences would be so great that we start calling the newly evolved one a new species.
Man has already been on this planet for over 50,000 years more or less in the same shape and physique. Except perhaps for a slight improvement in the size of the brain and his mastery over communication there will not be any conspicuous change. The gene pool remains more or less the same. Those who inhabited cooler climes got white skin instead of the dark one. The facial appearance has refined too. Otherwise he is still Homo sapiens.
