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.
Is kin selection the same as inclusive fitness?
Thus, in contrast to inclusive fitness, which considers genetic traits in both related and unrelated individuals, kin selection is concerned only with relatives.
How is altruism evolutionarily adaptive?
In evolutionary biology, an organism is said to behave altruistically when its behaviour benefits other organisms, at a cost to itself. So by behaving altruistically, an organism reduces the number of offspring it is likely to produce itself, but boosts the number that other organisms are likely to produce.
What is the meaning of kin selection?
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.
Which scenario is an example of kin selection?
Alarm calls are another popular example of altruistic behavior motivated by kin selection. In certain groups of closely related animals, such as squirrels and apes, members of the extended family will call out an alarm signal when a predator is within striking range.
Which is the best description of kin selection?
Lesson Summary. Kin selection is a type of natural selection where individuals will sacrifice their own lives in an effort to save closely related organisms; therefore, ensuring the survival of genes that they both share. The whole purpose of reproduction is to pass on genes to the next generation.
How is kin recognition related to altruism selection?
Kin recognition: First, if individuals have the capacity to recognise kin and to discriminate (positively) on the basis of kinship, then the average relatedness of the recipients of altruism could be high enough for kin selection.
Is the theory of inclusive fitness based on kin selection?
This analysis has been challenged, Wilson writing that “the foundations of the general theory of inclusive fitness based on the theory of kin selection have crumbled” and that he now relies instead on the theory of eusociality and “gene-culture co-evolution” for the underlying mechanics of sociobiology .
How is kin selection used in worker bees?
So, by caring for the new babies, the worker bees are making sure that those genes they share are going to be passed on to a new generation, without having to have offspring themselves. This caring for closely related individuals at the expense of personal fertility is known as kin selection. Kin selection is a type of altruistic behavior.
