Our Origin-I

People ask this question as soon as they start thinking – “who am I?” The privilege of asking this question is perhaps available to human being only. All other living beings, though some of them are provided with instinct and even some reasoning are incapable of asking this. This important question has been answered by science and religion along with details of origin of earth and history of evolution which is nearly one crore years old. About thirty lacs year is estimated period of human evolution and history which has also been confirmed by great scientists, Charles Darwin and Huxley. During 19th century they established all this as a genetic evolution system.
