Why should i trust the theory of evolution when Darwin himself said that if there was evidence to prove that lifeforms were more complicated than it was supposed there were - evolution was wrong. and when he said that if no evidence was found in the earth for evolution - it was wrong. and why do evolutionists hang on to their belief when there is no proof?
Evidence for evolution:
- Homologous proteins
- The near universality of the genetic code (eg the relation between codons and amino acids)
- Genetic drift in non-essential parts of homologous proteins
- DNA technology that can show relationship
- Developmental homology (ie ontogeny and it's relationship to phylogeny)
The interesting thing about most of these points of evidence is that it was predicted by Darwin's theory even though Darwin had no way of knowing about genes or biochemistry at all. Evolution as a theory is merely commonality of descent, and this evidence here is all evidence of evolution. It doesn't necessarily say that evolution is directed by natural selection, and it certainly doesn't say anything about the origin of life itself or God. But in experimental science, we can see evolution occurring, and natural selection is one of the major ways of that evolution (the other being artificial selection).
So when you take the reality of evolution--that is, the commonality of descent among all living things--as supported by a great deal of evidence, and you look for possible ways of directing that evolution, natural selection is the only theory that explains it with existing observable phenomena.
If you have a better way of explaining it with existing observable phenomena, and it fits all known data better than Darwin's evolution by natural selection, then by all means, let's hear it. Otherwise, you're objection is not to just evidence, but to SCIENCE ITSELF and the SCIENTIFIC METHOD. And I'm very sorry, but this method has been for too useful to abandon right now.
You have a complaint with science and think you have a better way? I'd like to hear it. Otherwise, you must face the reality that as of today evolution is an indispensable part of the scientific body of knowledge, along with Newton's descriptions of dynamics, Maxwell's electromagnetic principles, the three laws of thermodynamics, and Mendel's theories of genetic sorting.
