Evidences to support the theory of natural selection:

1. Artificial Selection: From ancient times, man is selecting good breed animals and plant for their use. In addition, they are performing cross breeding of these species to develop newer breed with derirable characters (Figure 8.2). The scientist supporting the Darwin’s theory explained the evolution through natural selection to give rise to newer species, just like following similar mechanism as artificial selection by man. They further added that natural selection is a slow process but much more complex compared to the artificial selection procedure.
