Does kin selection require kin recognition?

Does kin selection require kin recognition?

Kin recognition, also called kin detection, is an organism’s ability to distinguish between close genetic kin and non-kin. There is debate over this, since in strict theoretical terms kin recognition is not necessary for kin selection or the cooperation associated with it.

What are some examples 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.

Does kin selection apply to humans?

The viscous population mechanism makes kin selection and social cooperation possible in the absence of kin recognition. In humans, altruism is both more likely and on a larger scale with kin than with unrelated individuals; for example, humans give presents according to how closely related they are to the recipient.

Is kin selection the same as inclusive fitness?

Inclusive fitness suggests that altruism occurring among organisms who share a given percentage of genes enables those genes to be passed on to subsequent generations. Inclusive fitness applying only to relatives is called kin selection.

Which is the best description of kin selection?

Kin selection occurs when an animal engages in self-sacrificial behaviour that benefits the genetic fitness of its relatives. The theory of kin selection is one of the foundations of the modern study of social behaviour. British evolutionary biologist W.D. Hamilton first proposed the theory in 1963 and noted…

How is kin selection related to altruism and cooperation?

Hamilton’s proposal in 1964 that kin selection plays a role in the evolution of altruism, cooperation, and sociality. Kin selection is based on the concept of inclusive fitness, which is made up of individual survival and reproduction (direct fitness) and any impact that an individual has on the survival and…

How is kin selection based on direct and indirect fitness?

It is based on the concept of inclusive fitness, which is made up of individual survival and reproduction (direct fitness) and any impact that an individual has on the survival and reproduction of relatives (indirect fitness).

Who was the first person to discover kin selection?

British evolutionary biologist W.D. Hamilton first proposed the theory in 1963 and noted that it plays a role in the evolution of altruism, cooperation, and sociality; however, the term kin selection was coined in 1964 by British evolutionary biologist Maynard Smith.
