This is called artificial natural selection of the fittest and it should be obvious that it is certainly not the driving strong suit of evolution in natural ecosystems.

Homologous anatomical structures - antithetic evidence for evolution comes in the form of homologous anatomical structures which are similar in form and function except now which are found in seemingly heteroge neous species. Ex: Five-fingered limbs. - P! entadactyl limbs: penta means five and dactyl refers to fingers. - Darwin explained that homologous structures were not mediocre a coincidence but they are evidence that the organisms in scruple havge a common ancestor.
