      Because the world is constantly changing there can never be such a thing as a perfect species. For example, the diseases and parasites that each species has to deal with are constantly evolving to try to beat that species’ immune system, and so it must keep evolving to try and keep up. But all species have been equally affected by evolution. So you can’t really say that a species is “perfect”. Each species has evolved in the way it has because of the environment it has been in.

      If the species was perfect surely it would still be around? This is a very thought provoking question!!

      Good question. In a way evolution is constantly producing animals that are perfect for their environment. So think about how birds seem perfect to fly. They have wings that are the perfect shape, bones that are hollow so they are light, and feathers to keep warm and help them fly.

      Sam and Steven are right – isn’t it good to know that we and everything else around us is perfect (that is, until it goes exctinct)?

      It depends what you mean by perfect. As Sam and Steven say, species become adapted to their environments, so they tend to be almost perfect until the environment changes.
