Evolution is a Gradual Process
Evolution is a gradual process: Complicated organs, such as the eyes are selected of an advantage that they are not generated by a single DNA change. Such complex organs are created bit by bit over generations and seem to be a very popular adaptation. The structure is different in different organisms and is sufficient enough to suggest separate evolutionary origins. Feathers, e.g. evolved to provide insulation in cold weather, but later were adapted to be used for flight in animals like birds. In fact, some dinosaurs had feathers too, although they could not fly using them. Thus, we can infer that birds are very closely related to reptiles, since dinosaurs were reptiles. Sometimes, dissimilar appearing structures also evolved from common ancestors. Thus, evolutionary relationship can be established by studying fossils

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
