Summary Introduction
Introduction:
All the organisms living or extinct have been evolved from the single-celled organisms. Some of the mutations were favorable to organisms and they flourish and persist in the harsh environment of nature. The mutations in some of the organisms lead to drastic changes that were detrimental or caused no effect on them.
