How do altruistic behaviours arise through natural selection?
A)By his/her actions, the altruist increases the likelihood that some of its genes will be passed on to the next generation.
B)The altruist is appreciated by other members of the population because their survivability has been enhanced by virtue of his/her risky behaviour.
C)Animals that perform altruistic acts are allowed by their population to breed more, thereby passing on their behaviour genes to future generations.
D)Altruistic behaviours lower stress in populations, which increases the survivability of all the members of the population.
E)All of the options are correct.

Question

Quizplus · Accepted Answer

Altruistic behaviours arise through natural selection when an individual's actions increase the likelihood that some of its genes will be passed on to the next generation. This is known as inclusive fitness or kin selection. An individual may sacrifice its own reproductive success to help a close relative (who shares many of the same genes) reproduce, therefore indirectly ensuring that some of its own genes are passed on to future generations.
