- What is the possible reason why some cnidarians had evolved to a stony skeleton? plz include citationsssThe position where a spinal cord enters the skull provides evidence about whether a fossil species _______. a. was. nocturnal b. was carnivorous c. walked upright d. could speakWRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.

- 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?Professor Andrew, a paleontologist discovers a transitional fossil between a stem amniote and mammal. In 150 words express on what group of animals this might have belonged to and on their major antomical features !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?
