Human evolution, Biology

Assignment Help:

In the last unit we traced the human evolutionary history mostly from a palaeontological viewpoint. Although still fragmentary, the available fossil evidence makes it possible to construct a more or less coherent story of human origin and its development. Besides suggesting a primate ancestory, fossil evidence has indicated various trends in human evolution. Today the modern man is regarded as a climax of the evolutionary process. But several questions are raised as to which direction the human evolution is proceeding now and what direction will it take in the  future. Is the be-all and end-all of all the evolutionary process? Or do human beings continue to evolve biologically? It may not be possible to provide a direct answer to these questions since evolution is a long term process and the effects could be visualised only after tens of thousands of years.
