HEYA USER...

In order to explain evolution, a number of theories have been proposed. Some of the important theories are following.

Theory of special creation or divine origin: This is the most primitive theory and refutes the concept of evolution. According to this theory all living forms present on the earth were specially created once and for all by a supernatural power. Since all these organisms are of divine origin, they are permanent and non-changeable entities that exist in the same form in which they were created initially. Many of the religious faiths are based on this concept, for instance, Christianity believes that present world was created about 4000 B.C. and to be more precise, on 23rd of October, 4004 B.C. at 9:00 AM on Sunday as pronounced by Archbishop James Ussher in 17th century. Similarly, Hindu mythology says that Brahama, the God of creation, has created all the living organisms.

Idealistic Concept: Plato (428-348 B.C.) suggested that all observable things are imperfect representations of an ideal unseen world. According to this concept, initially there was a world of ideals (most perfect living forms) and any change in these ideals resulted into disharmonies (less perfect living forms). This concept was based on generalization of things and any variation to it was considered as an illusion.

Scale of nature concept: Aristotle (384-322 B.C.) extended the philosophy of Plato and arranged different living forms in the progressive fashion from most imperfect (simple) to most perfect (complex).
