Question

will advanced organisms be the same as Complex organisms and why

Answer 1

Advanced organisms will be the same as complex organisms. This is because the groups of organisms have acquired their particular body designs relatively, recently. There is a possibility that advanced or younger organisms undergo increasing complexity in body design during evolutionary time, to compete and survive.

Answer 2

It is not always true that an advanced organism will have a complex body structure. But, there is a possibility that over the evolutionary time, complexity in body design will increase. Therefore, at times, advanced organisms can be the same as complex organisms.
