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.)
inner fish 1. Why is it important (or interesting) to find transitional fossils? 2. What are the different lines of evidence that point to a shared ancestry among ourselves and other vertebrates? Invertebrates? 3. What processes (evolutionary, developmental, other) result in the changes in animal type the answer Write clear answers. not from quizlet
Cnidarians (and ctenophores) are diploblastic animals. What is the fate of the ectodermal and endodermal cells in cnidarians? Answer this by keeping track of structures /Nssues /cells of “organs” that are derived from the ectoderm or from the endoderm or both and by which group/taxa. Is there a common pattern for all or are there variations?
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?
Fill in the blanks w/ synapomorphic, symplesiomorphic, or neither: The presence of brain regionalization is a __ feature of tetrapods relative to conditions in other vertebrates, but is a __ feature of Chordata considered alone. The presence of a post-anal tail, a dorsal hollow nerve cord, a notochord, and external gills are __ features of Chordata, __ features of Urochordates, __ features of (cephalochordates + vertebrates) relative to conditions in other organisms.
6. Organisms classified as “birds” share a common feature. What shared derived character defined this taxonomic group? 7. What feature is present in all animals but is not present in birds and reptiles? 8. Reptiles, birds, and mammals are amniotes. I’m addition to an amniotic egg, the common ancestor of all reptiles, birds, and mammals had a thick epidermal layer of scales partially composed of a protein called keratin. Keratinized skin helps prevent water loss in terrestrial environment. A. what type (or form) of Keratinized epidermal structure represents the ancestral character state of all reptiles, birds, and mammals?
EVOLUTION CONNECTION Living members of a vertebratelineage can be very different from early members of the lineage,and evolutionary reversals (character losses) are common. Giveexamples that illustrate these observations, and explain theirevolutionary causes.
What is the possible reason why some cnidarians had evolved to a stony skeleton? plz include citationsss
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.
