Concept explainers
Concept introduction: Behavior is the capacity of an organism to learn through experience. Behavioral ecology is study of how natural selection shapes the behavior of an organism. Behavioral traits are influenced by an organism’s environment. Some environmentally-induced variations in behavior occur due to epigenetic effects.
Answer to Problem 1SQ
Correct answer: Genes affect the behavior of individuals by influencing the development of nervous system, affecting the kinds of hormones in individuals, and determining which stimuli can be detected. Option d. is given as “all of the above”. Hence, option d. is the correct answer.
Explanation of Solution
Reason for the correct statement:
Studies of behavioral differences within a species or among related species can shed light on the proximate causes of a behavior and the ultimate causes that favored the behavior.
Option d. is given as “all of the above”. Behavior starts with genes that influence the development and the activity of the nervous and endocrine systems. Behavior is often a triggered response to a stimulus. This also affects the hormones in the individuals. Hence, option d. is the correct answer.
Reasons for the incorrect statements:
Option a. is given as “influencing the development of nervous system”. This is not the only factor that is affected by the genes. Hence, option a. is incorrect.
Option b. is given as “affecting the kinds of hormones in individuals”. This is not the only factor that is affected by the genes. Hence, option b. is incorrect.
Option c. is given as “determining the stimuli can be detected.” This is not the only factor that is affected by the genes. Hence, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
Genes affect the behavior of individuals by various factors such as influencing the development of nervous system, affecting the kinds of hormones in individuals, and determining which stimuli can be detected.
