EVOLUTION

If we look around we see many kinds of plants and animals. They differ from each other in different characters. When one studies about plants and animals the first question that arises in his mind is about origin and evolution of these plants and animals on earth. How they originated? When they originated? How they evolved and give rise to the diversified animals? Whether God has created them as such or they have changed slowly during their life in different lines and now exist as such? From ancient times scientists are trying to solve these questions. The most important question before them was how life originated and how they evolved? We now know that life originated in water. These are considered as simple and lower plants and animals. These then invaded the land and changed according to the surrounding to live in the changed atmosphere. This change was slow and ultimately gave rise to complex and higher plants and animals. So we can define evolution as a slow and progressive change resulting in increasing complexity of living simple and lower plants and animals which has taken place during millions of years to give rise to different complex and higher plants and animals on this earth.
