This West Indian manatee (Trichechus manatus) is an aquaticmammal. Like amphibians and reptiles, mammals are tetrapods (vertebrates with four limbs). Explain why manatees areconsidered tetrapods even though they lack hind limbs, andsuggest traits that manatees likely share with leopards andother mammals (see Figure 26.12b). Discuss how early members of the manatee lineage might have differed from today’smanatees.

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?
Neanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. They shared Europe for 10,000 years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthals has generated much debate. Why did Neanderthalsbecome extinct? State at least two major factors toexplain their fate.
Many species of animals make alarm calls, whichwarn others in their group that a predator isapproaching. Alarm calls also attract the attention of the predator, making it more likely thatthe individual making the call will be eaten. Whymight natural selection favor the evolution ofalarm calls in a species? How might you test thathypothesis?
Nothartcus is an extinct early primate that lived around 50 million years ago. With long curved fingers and naisl instead of claws, it was one of the earliest hands that looked like ours. True or false?

What is the best evidence that Monotremes are a transitional taxon between reptiles and other mammalian groups? O A. they have fur, have mammary glands without nipples, have a cloaca and lay leathery eggs. O B. They have poison glands like a snake, have a tough beak, have web-feet like a beaver, and give birth to live young. O C. their reproducive tract resembles a kangaroo's but they lay eggs and lack a marsupial pouch O D. they have fur, lay eggs but don't suckle their youg as they lack mammary glands, and appear in the fossil record before the placental mammals. 11:52 Al 12/16/202 ere to search End F10 PgUp PF11 F12 PrtScn Home F9 DII F5 F7 F6 F4 F3 F2 F1 & %3D 23 2$ 9. 7 3 4 W J K L S D F C V .. .- * CO
