Whale skeletons contain nonfunctional pelvic bonesa. as a result of convergent evolution.b. due to catastrophism.c. because whales evolved from ancestors that had hind legs.d. because the bones might be needed for a future adaptation.
All mammals have tailbones and muscles for moving a tail. Even humans have a reduced tailbone and remnant tail-twitching muscles, though these features have no apparent usefulness. These traits in humans would best be described as (a) convergent structures. (b) fossil evidence. (c) evidence from biogeography. (d) vestigial traits.
Organisms that are closer together on a cladograma. are in the same family.b. comprise an outgroup.c. share a more recent common ancestor than those organisms that are farther apart.d. share fewer derived characters than organisms that are farther apart.
