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?

In the animal kingdom today, poikilotherms outnumberhomeotherms by a great margin. Why is poikilothermy asuccessful way of life even though poikilotherms sometimesmust compete successfully with homeotherms to survive?
Mammals are most successfulland dominant animals todaygive evidence?
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?
referring to Figure 1.20, provide a possible explanationfor how, over a very long time, the green warbler finchcame to have a slender beak.
How humans learn and remember things is still one of the major unsolvedbiological mysteries. Much of what is currently understood about learning andmemory and the biological basis of behaviour comes from the study ofinvertebrates, including the gastropod molluscs. Describe the types ofexperiments that have been performed on gastropods and the extent to whicheach has increased our understanding of how animals learn.
House sparrows (Maya) were introduced to North America in 1852. Since that time thesparrows have evolved different characteristics in different locations. Sparrow populations inthe north are larger-bodied than sparrow populations in the south. This divergence inpopulations is probably at least partly a result of natural selection: larger-bodied birds canoften survive lower temperatures than smaller-bodied birds can. Colder weather in the northmay select for larger-bodied birds. What type of evolution based on natural selectionaccounts for this observation? Explain your answer.
Look at your feet. What feature of the arrangement ofyour toes provides evidence of an evolutionary history thatinvolved a tree-dwelling lifestyle?
Insects are the largest group of animals on Earth. Insectdiversity is greatest in the tropics, where habitat destructionand species extinction are occurring at an alarming rate.What biological, economic, and ethical arguments can youadvance to persuade people and governments to preservethis biological diversity?
This honeypot ant (genus Myrmecocystus) can store liquid foodinside its expandable abdomen. Consider other ants you arefamiliar with, and explain how a honeypot ant exemplifiesthree key features of life: adaptation, unity, and diversity.
Gould wrote his passage as a criticism of his fellow evolutionary biologists. Of the following statements about the human eye, which would those biologists agree with the most? A. The eye has lost its purpose and it's obsolete. B. The eye is a perfect fine-tuned machine well suited to its purpose. C. The eye has a use, but it was not evolved for that use.
If you discovered a fossil of an extinct mammal thatlived high in the Andes, would you predict that it wouldbe more closely resemble present-day mammals fromSouth American jungles or present-day mammals thatlive high in African mountains? Explain.
