Pls & thank you! 8. a) As you know, the largest mass extinction in the history of life on earth was the Permian extinction that occurred about 252 million years ago. The therapsids are often described as “mammal-like reptiles”. If the Permian extinction had caused the extinction of the therapsids, would mammals as we know them now have evolved? Why or why not? 8. b) Many lines of evidence, including biochemical evidence, show that living birds are direct descendants of dinosaurs. A number of dinosaur lineages had feathered dinosaurs, not just the lineage that includes living birds. Do you think that is it justified to believe that all feathered dinosaurs had behaviors known from living birds? Such behaviors of birds include colonial nesting, sexual displays by males using feathers, males moving to display their ornamental feathers to female mates. Give a brief reason for your answer. 8. c) A…Matcht eh follo0wing Superclass Agnatha 12345678 Class Aves 12345678 Class Reptilia 12345678 Class Chondrichthyes 12345678 Class Cestoda 12345678 Class Osteichthyes 12345678 Class Amphibia 12345678 Class Mammalia 1.
