(i ) Evolution is not always equated with progress because evolution simply generates diversity, and this diversity helps in better adaptation and survival.
(ii ) Evolution creates complex body designs, but this does not imply that simpler forms are inefficient. For example, bacteria having simple organisation are more capable of surviving in extreme environments than organisms with complex body designs.
(iii ) Human beings and chimpanzees have both evolved from a common primate ancestor, but there is no progress associated with the evolution of chimpanzees.
(iv ) Human beings should not be considered as the highest evolved species or the climax species. They are only a branch of evolution.
