Question
Chapter 51.4, Problem 1CC
Summary Introduction
To explain: The reason why the geographic variation in the garter snake might indicate that the behavior has evolved due to natural selection.
Concept introduction: There is a geographic distribution of the garter snake according to the habitat and the region. The food of the snake depends upon the availability of food in the surrounding habitat. An experiment designing revealed that the food acquired by the snake changed especially for the pregnant mother garter snakes.

Explain the difference IN PRIMATES between contest competition and scramble competition, referencing how the distribution of different types of foods interacts with group size to affect levels of these kinds of competition in primate groups.

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.

- Behavior influences how organisms experience the environment and thus patterns of natural selection on behavioral traits. Which of the following examples is consistent with this statement? Some lizards in complex tropical forests prefer to hang out on tree trunks and branches, rather than the ground substrate, which has resulted in selection for shorter relative limb length and toe pads that can cling to bark. Ground-burrowing mammals experience greater exposure to dust and increased selection on their respiratory system to filter these particulates. Specialist parasitoids only target a handful of different host/prey types, resulting in a predictable resource and less selection on the ability to learn new resources All of the above Imagine that scientists have just discovered a weird new marine tunicate at extreme depths of the ocean.

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_forward
- Do the following two hypothesis supports their graphs? Explain. Figure 1: The hypothesis for novice vs. experienced foraging is that animals who have been foraging for ages should have a greater chance of survival than beginner foragers since they are more skilled and invest less time looking for food.
