Concept explainers
To compare: The cost and benefits of dominance hierarchies and territoriality.
Introduction: The process of mating is dominated by the big and strong individual of a species. In the sociobiology, the presence of a number of individuals does not mean it is social. Dominant hierarchy is represented by the ranking of social status in which one animal has a higher status when compared to the other animals which are lower in rank. The social behavior is described as the interaction of two animals which represents the common species. Territoriality is exhibited by certain species of animals, where these animals defend their territory against individuals of the same species or individuals of different species.

- Can Kin selection explain eusocialty?arrow_forwardWhat are some other prezygotic reproductive barriers besides a mating dance?arrow_forwardDescribe and give an example of a dominance hierarchy. What role does it play in social behavior? Give a human parallel, and describe its role in human society. Are the two roles similar? Why or why not? Repeat this exercise for territorial behavior in humans and in another animal.arrow_forward
- Earlier explanations of altruistic behavior as a form of group selec-tion have been supplanted by Hamilton’s hypothesis of kin selection. What distinguishes kin selection and how does it accord with the no-tion of inclusive fitness, the relative number of an individual’s alleles that pass to the next generation?arrow_forwardWhat are some costs and benefits of territoriality?arrow_forwardPolygyny is a form of polygamy in which a male mates with more than one female. Explain how three forms of polygyny differ from each other: resource-defense polygyny, female-defense polygyny, and male-dominance polygyny.arrow_forward
- What are indirect fitness benefits of siblicide? When would an individual gain more from siblicide than from inclusive fitness benefits? When might it be worth it for a subordinate to fight to the death with its dominant sibling?arrow_forwardIntrasexual selection favors traits that enhance direct competition among individuals of the same sex. are attractive to the opposite sex. increase survival. are easily adapted to change.arrow_forwardGive typing answer with explanation and conclusionarrow_forward
