The diversity of modern vertebrates was shaped in partby mass extinctions. The most severe extinction eventwe know of occured at the border between the Permianand Triassic periods about 250 million years ago. Anestimated 96 percent of the marine species and 70 percentof land species disappeared in what is sometimes called“The Great Dying.” The cause of this mass extinctionremains under investigation. Suggested causes includean asteroid impact, extreme volcanic activity, or a sudden release of carbon dioxide from deposits on the sea floor. Which groups of vertebrates were present when this mass extinction event occurred? Which evolvedafterward?
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.
In 1798, a stuffed platypus specimen was delivered tothe British Museum. Reports that it laid eggs createdmuch confusion. To modern biologists, a platypus isclearly a mammal. It has fur and the females producemilk. Young animals have typical mammalian teeth thatare replaced by hardened pads of the “bill” as the animalmatures. Why do you think modern biologists can moreeasily accept that a mammal can have some reptileliketraits than scientists who were considering this animal inthe late 1700s?

The legend on the bottom left reflects three basic conditions that describe the character that pertains to body covering (or integument). The conditions that pertain to the specific taxa at the top of the tree are shown by the numbers. Dinosauria Trace the integument character along the tree (you may want draw it out on a separate sheet of paper). Once you have done that step, consider the ancestor of all dinsoaurs.
