What is an example of kin selection?

The honeybee and other social insects provide the clearest example of kin selection. They are also particularly interesting examples because of the peculiar genetic relationships among the family members. Male honeybees (drones) develop from the queen’s unfertilized eggs and are haploid.

What are two reasons for kin selection?

Hamilton proposed two mechanisms for kin selection. First, kin recognition allows individuals to be able to identify their relatives. Second, in viscous populations, populations in which the movement of organisms from their place of birth is relatively slow, local interactions tend to be among relatives by default.

Is kin selection true?

It is true that the kin selection approach (in both its neighbor-modulated and inclusive fitness guises) has received more theoretical attention than the group selection approach and has been put to work in more empirical applications.

Is inclusive fitness the same as kin selection?

Thus, in contrast to inclusive fitness, which considers genetic traits in both related and unrelated individuals, kin selection is concerned only with relatives.

How do we define kin selection?

: a theory of natural selection which states that a usually altruistic behavior or attribute that lowers the fitness of a particular individual is selected for if it increases the probability of survival and reproduction of related kin who possess some or all of the same genes as the altruistic individual.

What is group selection theory?

Group selection is a proposed mechanism of evolution in which natural selection acts at the level of the group, instead of at the more conventional level of the individual. They argued on the basis of mathematical models that individuals would not altruistically sacrifice fitness for the sake of a group.

What kin selection means?

kin selection, a type of natural selection that considers the role relatives play when evaluating the genetic fitness of a given individual. Kin selection occurs when an animal engages in self-sacrificial behaviour that benefits the genetic fitness of its relatives.

How does kin selection work?

What is the Hamilton rule?

Hamilton’s rule asserts that a trait is favored by natural selection if the benefit to others, B, multiplied by relatedness, R, exceeds the cost to self, C. Specifically, Hamilton’s rule states that the change in average trait value in a population is proportional to BR−C.

What is the meaning of kin selection?

What’s the difference between altruism and kin selection?

The main difference between kin selection and reciprocal altruism is that kin selection favors the reproductive success of the other relatives even at a cost to the organism’s own survival and reproduction. Furthermore, kin selection uses shared genes, while reciprocal altruism does not use shared genes.

What is the difference between kin selection and reciprocal altruism?

Reciprocal altruism is the altruism that occurs between two unrelated individuals. Kin selection is an evolutionary strategy which favours the reproductive success of relatives even at a cost to the organism’s own survival and reproduction.
