A similar argument has been made for cetaceans with "legs" that leaves me undesired. Those are anchor points similar to a snakes spurs that aid in copulation. This, to me, is just another case of percieved lineage that relies on circumstantial evidence to present its case. Certain scientists may be inclined to claim that they are atavistic legs when in reality all it is an anchoring mechanism to aid in sex.
see this is were you are not really understanding evolution, the organs lost most of their use as legs and were co-opt as anchers for reproduction, since this is also a secondary fuction of legs as well.
ever seen animals on animal planet they use thier legs to hold on to the females
plus in snakes they sometimes do no reabsorb the legs so some snakes are born with them developed, which is how we know they had legs
