'Life' is undoubtedly one of the biggest puzzles facing modern science. From physicists to philosophers, people from almost all walks of life have been trying to make sense of this insanely complex problem. The idea of 'life' is intricately linked with the idea of 'evolution'. If something does not evolve, it is very unlikely to be called living. Some philosophers and scientists have suggested that the distinction between living and non-living is quite artificial (eg. viruses) and this does make sense to some extent. But biological evolution is something that still enables us to draw a distinction between these two worlds. Lot of research has been done on various aspects of evolution and we do understand many details of the process, thought lot still remains to be understood. But what is still very far from being clear is this question: what is evolution really trying to do?
