Common dolphin Ichtyor Ichthyosaurs were aquatic dinosaurs. They had dorsal fins and flippers that, at least superficially, resemble dolphins, even though their closest common ancestors were terrestrial reptiles that had neither dorsal fins nor aquatic tails. (See figure at right) Titelů The members of lineages between the dolphins and ichthyosaurs do not have adaptations such as -streamlined bodies -long ased with teeth -Ins and hopers 4. Using terms and concepts from class explain why these organisms look so similar to...

All of the features below are features that characterize humans,
though very few of them are unique to humans. Rather, most of them
are present in our species because of our evolutionary history
(they were present in an ancestral species at some point in time,
and eventually passed on to us). For example, the bilateral
symmetry that characterizes the human body plan is a feature that
evolved in a primitive animal species that lived hundreds of
millions of years ago;...
