Evolution is the alteration of nheritable traits of the biological populations over a series of generations. In biology, it means to observed organism’s changes, to the descent of a common ancestor and at a technical level to a gene frequency change over time. The processes lead to diversity over a large biological organization, including the molecular evolution’s level, individual organisms and the level of species (Gregory 2009). Each and every life on Earth originated from a common descent from a last universal ancestor, whose time of existence is approximated at 3.5-3.8 billion years ago. Repeated creation of Continue reading...
