Summary Introduction
Introduction:
Behavioral ecology is the study of animal behavior based on the evolutionary process due to ecological changes. If an organism’s behavioral trait gives a selective advantage, natural selection favors it. Adaptive value refers to the traits that induce the reproductive fitness or reproductive success in an animal. Natural selection selects these behavioral traits responsible for the adaptation.

Behavioral ecology assumes
a. that all behavioral traits are innate.
b. learning is the dominant determinant of behavior.
c. behavioral traits are subject to natural selection.
d. behavioral traits do not affect fitness.
A social interaction between an actor and a recipient can influence their relative fitness. When the outcome of such an interaction brings harm to both participants, the action is described as being _________.
A. asymbiotic.
B. spiteful.
C. antagonistic.

. Hamilton suggests altruistic behaviors are favorable when
A. cost/benefit is greater than the coefficient of relationship

C. benefit/cost is less than the coefficient of relationship
D. None of the above
.Hamilton's rule (where r is the degree of relatedness, B is the benefit to the
recipient, and C is the cost to the altruist) predicts that natural selection should favor
altruistic acts under certain circumstances. Which of the following circumstances are
unlikely to lead to selection favoring altruism?
