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. References are the books  "Primate Behavioral Ecology" by Karen Strier and "Planet Without Apes" by Craig Stanford
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. CHARACTER SEXUAL DIMORPHISM MALES FEED YOUNG Cassin's Vireo No No Red Fox Sparrow Cape May Warbler Cedar Waxwing Golden-Crowned Kinglet Pyrrhuloxia Yes No No No No Yes No Yes Yes No California Gull No Yes Note: This data is fictional 5) Which of the hypotheses in part 4 is consistent with your analysis? Explain why in a brief paragraph.
