QUESTION 5 Although it is rare, some cetacean species have occasional individuals with hind paired flippers in addition to their anterior paired flippers. Mark all answers that correctly describe this phenomenon. forelimb flippers hindlimb flippers These structures are convergent with hind limbs in other mammals as the whale has no ancestors with hind limbs. This is most likely the result of horizontal gene transfer between the whale and another organisms that has hind limbs, such as a sea lion. O The most reasonable explanation for this condition is a remnant of the ancestral mechanism for hind limb development, as cetaceans evolved from four legged ancestors. O These structures, when present, could be referred to as vestigial because they are a non-useful remnant of an ancestral structure that was once and important feature.
