evolution would automaticly be an ascent wwith perfection as a "target".
No this is to misunderstand evolution, it has no target.
You seem to be attached to a common myth that was known as the “Great Chain of Being” with god reigning supreme over all his creatures in their place.
In fact it makes no sense to think in terms of higher or lower creatures.
For example, it seems obvious that chimpanzees are higher animals than earthworms doesn’t it? We may even assume that evolution makes this fact even clearer and justifies it. In fact such thinking is deeply flawed and antithetical to evolution.
Consider what we may actually mean when we assert that chimps are “higher” than earthworms.
1. Perhaps we have in mind that monkeys evolved from earthworms - This is a just plain wrong, chimps and worms share a common ancestor. It is this kind of thinking that causes creationists to ask daft questions like why are there still chimps today if they evolved into humans? Or, where are the fossils of all the crocoducks or fronkeys? Australian creationist John McKay has been touring British schools, masquerading as a geologist, and teaching children this kind of nonsense.
2. We may mean that the common ancestor of chimps and worms looked a lot more like a worm than a monkey – This may be true but it really tells us nothing useful about the two creatures we are comparing. It’s just as likely that both animals have diverged equally in different directions from their common ancestor. Also it is likely that different parts of an animal will be more or less “primitive” than other parts. For example a horses hoof is simpler than a human foot (it has a single digit to our 5) but it is the human foot that is more “primitive” our common ancestor had 5 digits.
3. Often there are any one of a number of odd assertions in our mind when we try to rank animals by some arbitrary scale – cleverer, prettier, bigger genomes, more complicated body plans etc. These are all pointless judgements. Animals may rank highly on one ladder and poorly on another. A salamander has a smaller brain than some mammals but it has a bigger genome!
4. Often we are in fact judging how much an animal is similar to us humans when we rank them in our minds. Why? This is a very important point that we need to get over if we are going to understand the world. Evolution had no point, it has not been slaving away all these years for the purpose of making you and I. This is why we find ourselves asking questions like “what is the point of cockroaches?” There is no point; they are gene machines just like us. Do not make the mistake of using humans as the gold standard of living things.
5. OK so at least are chimps are better evolved to survive than lower animals? This assumption just does not hold up. Insects rule the world while some of our most majestic creature teeter on the edge of extinction.
Evolution is a purposeless process.
