MAKE CONNECTIONS Many new animal body plansemerged during and after the Cambrian explosion. Incontrast, cnidarians today retain the same diploblastic,radial body plan found in cnidarians 560 million yearsago. Are cnidarians therefore less successful or less “highlyevolved” than other animal groups? Explain.(See Concepts 25.3 and 25.6.)

MAKE CONNECTIONS Historically, annelids and arthropods were viewed as closely related because both havebody segmentation. Yet DNA sequence data indicatethat annelids belong to one clade (Lophotrochozoa) andarthropods to another (Ecdysozoa). Could traditionaland molecular hypotheses be tested by studyingthe Hox genes that control body segmentation (seeConcept 21.6)? Explain.

Explain why they are described as such and describe the environment in which they probably lived. Q9. __________________ and _____________________ are early tetrapods that do not have features unique to fish. Describe how these two species differ anatomically and what that means about where they each lived.

Propliopithecids vs. Parapithecids. Adapids and Omomyids. Dryopithecus and Oreopithecus. With the exception of Gigantopithecus, many students struggle to differentiate between the various fossil primates. So, let's write about them, have a little fun, and help embed them in our brains. Create an original comic or storyboard that illustrates one of the fossil primates. Unlike the Primate Profiles, this is NOT meant to be a research project! This is meant to be a study tool for you. You should build comics primarily, if not exclusively.
Expound and Elaborate: Mammals belong to a group of amniotes known as synapsids. Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of:a. Embryonic developmentb. How the young are fedc. Period of gestation
