Classification Depending on Evolution
Classification Depending on Evolution
The classification of organisms is closely related to their evolution. Evolution refers to the process by which the early organisms on the earth diversified into various forms through a slow and continuous process. The older forms have given rise to the newer forms. But the newer forms are sufficiently different to be recognized as new types (species) which breed amongst their own members and not with the ancestral types. The newly formed species in turn may give rise to still newer forms. This results in the complexity of structure, i.e., the older organisms are simpler and the younger organisms are more complex.
Evolution has two main perspectives:

My 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.
