Chapter 39.6, Problem 1CC
Summary Introduction
To determine:
That the choice of the prey of the garter snake is evolved by the natural selection.
Introduction:
Behavioral differences can be observed in the same species based on the location where the species inhabit. This behavioral variation can lead to

You want to distinguish between two hypotheses to explain the patterns you see:
1) Males not feeding the young is an adaptation to dimorphism
2) If males don't feed the young in a species, it will allow them to become brightly colored
To begin to address this question, map the characters changes in dimorphism and males feeding
the young onto each of the trees on the previous page.

- 1) Think back to the example of ovenbird evoluon in South America. Ovenbirds are a diverse family of small, insect-eang birds that live mainly in South America. Different ovenbird species have adapted to rocky ocean shorelines, snowy mountains, scorched deserts and tropical rainforests. Like finches, ovenbirds have a variety of beak sizes and shapes, an important indicator of food preference that makes them ideal for studying evoluon. In ovenbirds, "some [beaks] are long and down-curved, like a scythe, for probing into crevices in tree bark and others have short dagger-like bills." What conclusions did the researchers reach? A) ovenbirds are diverse because they do not share any common ancestors B) ovenbirds because successful because they are not native to the area and could easily colonize the area C) birds have different beaks that help them exploit different resources and avoid competition 2) One ant species from Africa is best at competing for space, but is worse at colonizing a…arrow_forwardDiscuss the costs and benefits of allomothering behavior, and describe the conditions under which the frequency of allomaternal behavior varies across different primates.

Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.arrow_forwardIn the eclectus parrot (Eclectus roratus), mothers sometimes take parental favoritism to extreme lengths by killing their sons, but never their daughters (Heinsohn et al. 2011). Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes. Don't write from any online source..arrow_forward
- 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.
