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 is an example of kin selection?
The honeybee and other social insects
provide the clearest example of kin selection. … So any behavior that favors honeybee sisters (75% of genes shared) will be more favorable to their genotype than behavior that favors their children (50% of genes shared).
What is kin selection quizlet?
Kin selection. selection
favoring alleles that increase indirect fitness
, it is not altruism because it acts to increase indirect fitness. Hamilton’s rule.
What is known as 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.
What is kin selection in psychology?
Kin Selection. Definition. Otherwise known as inclusive fitness theory, kin selection refers to
the theory that people have evolved to favor others who are genetically related to them
. The logic of the theory is that a gene can propagate itself through two routes.
What is the purpose of kin selection?
Kin selection is important because it can
explain altruistic behavior
, such as in workers of the social insects. However, it can also explain selfish behaviors and is important for understanding conflicts between individuals.
What is Hamilton’s rule?
Specifically, Hamilton’s rule states that
the change in average trait value in a population is proportional to BR−C
. This rule is commonly believed to be a natural law making important predictions in biology, and its influence has spread from evolutionary biology to other fields including the social sciences.
How does kin selection work?
Kin selection is a part of natural selection. Selection normally
favors a gene if it increases reproduction
, because the offspring share copies of that gene, but a gene can also be favored if it aids other relatives, who also share copies. It is this selection via relatives that is referred to as kin selection.
what is kin selection and altruism and how are the two related?
Kin selection is when indivduals choose to ensure that their genes and other close genetic relatives survive by producing offspring
. Altruism is behaviour that is performed for the benefit of others.
What is animal reciprocity?
In evolutionary biology, reciprocal altruism is
a behaviour whereby an organism acts in a manner that temporarily reduces its fitness while increasing another organism’s fitness
, with the expectation that the other organism will act in a similar manner at a later time.
How do you explain natural selection?
Natural selection is the
process through which populations of living organisms adapt and change
. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Does kin selection occur in nature?
According to Hamilton’s kin selection theory (also known as “inclusive fitness” theory), kin selection is
the process by which social evolution occurs in nature
.
Which of the following is an example of kin selection altruism?
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.
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.
What is empathic joy?
The Empathy Joy hypothesis states that
the reason for someone helping another in need are positive feelings associated with the altruistic behavior
. Helping others is a reward in itself because it brings a person happiness and joy when they commit a helping behavior.
What is an example of altruistic behavior?
Altruism refers to behavior that benefits another individual at a cost to oneself. For example,
giving your lunch away
is altruistic because it helps someone who is hungry, but at a cost of being hungry yourself. … Recent work suggests that humans behave altruistically because it is emotionally rewarding.
