Comparisons of genetic information from various invertebrate groups has
 
  a. confirmed nearly all classifications that were based on phenotypic resemblances.
  b. provided a complete and final picture of animal phylogeny.
  c. led to a decision to forgo formal classification of animals, as animal relationships are too
  complex to determine.
  d. led to a reworking of the classification of animals that is still being refined.
  e. confirmed that some invertebrates should be classified as vertebrates.
