the evidence of which organs in the study of evolution do not indicate common ancestors?
Answers
Answer:
Vestigiality refers to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species, but have been retained during the process of evolution. Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment. Homology refers to the traits inherited by two different organisms from a common ancestry. Analogy refers to the similarity in function of two different organisms due to convergent evolution and not common ancestry. So, all of these show the evidence of evolution. Thus, option D is correct.
