This West Indian manatee (Trichechus manatus) is an aquatic mammal. Like amphibians and reptiles, mammals are tetrapods (vertebrates with four limbs). Explain why manatees are considered tetrapods even though they lack hind limbs, and suggest traits that manatees likely share with leopards and other mammals (see Figure 20. 12b). How might early members of the manatee lineage have differed from today's manatees?

Essay on (2 pages): Dogfish sharks (Squalus acanthias) represented “primitive” gnathostomes and cats (Felis catus) represented the “derived” state. Was this appropriate? How does the anatomy of a cat reflect humans’ shared ancestry with sharks?
Which is NOT an example of a structural homology? Please choose all applicable options. a) All vertebrate embryos form pharyngeal pouches.b) Vertebrate forelimbs generally have the same number and a similar arrangement of bones.c) The same group of embryonic cells forms the adult jaw of a perch and of a dog.d) All organisms share a common genetic code.
Human embryos have tails which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and
mammals Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?
a close evolutionary connection between humans and many other mammals
a very distant evolutionary connection between humans and many other mammals
a very distant evolutionary connection between humans and many other reptiles
a close evolutionary connection between humans and many other reptiles

- INTERPRET DATA Which of the primates in Figure 18-18 is the most distantly related to humans? Explain your answer. Figure 18-18 Differences in DNA nucleotide sequences as evidence of evolutionary relationships Comparing the same gene in different organisms provides a window into evolution. Here the differences in the non-protein-coding region of the -globin gene are compared between humans and other primates. Evolutionary biologists are rapidly expanding such studies from comparing one or several genes to comparing entire genomes.arrow_forwardThe tree shows one lineage of ornithischian dinosaurs and many lineages of theropoddinosaurs.

Some paleoanthropologists believe these specimens represent one species, but differ because one is female and one is male. Others believe them to be different species. What do you think? Support your answer using anatomical evidence. Name the key anatomical features and behaviors that set the earliest member of our genus, H. habilis, apart from the australopithecines and that are defining characteristics of the genus Homo.arrow_forward
- Neanderthal fossils were first discovered in the nineteenth century. Study of their morphology suggested that Neanderthals were more closely related to humans than any living species of primate was. Much later, it became possible to sequence DNA from Neanderthal fossils and compare the sequences to those from other primates. Did the results confirm or refute the earlier conclusions based on morphology?

However, animals with ancestral characteristics still successfully exist on Earth today. Why is this so? Why have the animals with derived traits not completely replaced the ones with ancestral traits? Use examples from the lab to illustrate your answer. examples cephalochordata jawless fishes jawed fishes tetrapods ratarrow_forward
- Most animals show derived characteristics (character states) that differentiate them from their common ancestor (ancestral character state). However, evolution can also move in reverse, involving the change of a derived character state back to an ancestral state. Provide two examples from invertebrates of such ‘reverse evolution’ from a derived state (specialized state) back to a more ancestral character state. Make sure to use examples provided in this class.
