Another question is if Natural selection is capable of creating new species. In this case would darwinists put more stress on random mutation that makes possibilities from which natural selection can choose.
In thread discussing cospeciation they put more stress to natural selection - in other case cospeciation would lead to conclusion that it originated by "chance alone".
Darwinists minds are captured in the prison of "random mutation" and "natural selection" concepts which blind their reasoning completely. Once it is fit of "random mutation" then fit of "natural selection" combined with "sexual selection".
They try to explain all secrets of Nature using these concepts that were never observed to create new species. Belief in natural selection is so strong that they suppose it to be also there where we do not detect it by reason and experience - like in the case of white coloration of swans, or in many cases of curious mimicry discussed elsewhere. Having only phantasy they try to create stories how natural selection forms organs and coloration of species that helps them survive and also those that have no connection to survival. In that case they suppose that such connection existed once or we cannot detect it but it exist - we must only believe. To believe that natural selection combined with random mutation is allmighty evolutionary force that disclose all secret of Nature is only foundation that darwinism is resting upon.
Of course there are many scientists who deny Natural selection as evolutionary force - they consider it as only maintaing force that removes extremities. Eimer, Heikertinger, Suchantke and all great men mentioned in Davison's Manifesto.
