Altruistic behavior in groups of related individuals is most likely driven by kin selection since related individuals would share DNA.

Question

Which of the following pieces of evidence would be most likely to weaken this argument?
(1 point)
Data showing that the more frequent an allele of a gene occurs in a population, the more likely that population performs altruistic behaviors
Data showing that individuals that share a higher percentage of DNA in a group tend to show the most altruistic behavior between themselves
Data showing that food gifts are given more commonly among family members than between unrelated individuals in a group
Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other

Answer 1

The piece of evidence that would most likely weaken the argument that altruistic behavior in groups of related individuals is driven by kin selection is:

Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other.

This evidence suggests that altruistic behavior may occur among individuals who are not closely related, contradicting the idea that such behavior is primarily influenced by genetic relatedness and kin selection.
