Amniotes are those reptiles which have amniotic layer in their eggs protecting their embryos. Synapsids have a single opening in their skull, diapsids have 2 and anapsids have no opening in the skull. Amniotes have evolved in to number of lineages giving rise to birds and mammals too. So, reptilia does not include all descendants of the amniotes. So they form a paraphyletic group.

Exercise: Many older classifications are not monophyletic, and do not reflect the evolutionary relationships among species. As an introduction to phylogenetic classification, think about the tetrapods (animals with four legs). These animals have traditionally been classified into four groups, all of the same rank: Class Amphibia (frogs, salamanders, newts, etc.) Class Reptilia (snakes, lizards, crocodiles, turtles, etc.) Class Aves (birds) Class Mammalia (mammals) Reptiles possess a common ancestor with certain extinct amphibians, the birds are derived from a group of...

11. For this question, refer to FIG. 24.2 (p. 487) "The family tree of the lesser and great apes."This figure shows the derivation of "earlobes". Assume that evolution has not reversed this character state in any of the descendants of this ancestor which evolved earlobes. Given this, what do we know about earlobes?

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;...
