Consider the following argument:
Altruistic behavior in groups of related individuals is most likely driven by kin selection since
related individuals would share DNA.
Which of the following pieces of evidence would be most likely to weaken this argument?
(1 point)
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 the more frequent an allele of a gene occurs in a population, the more likely
that population performs altruistic behaviors
Data showing that only distantly related individuals are most likely to perform altruistic behaviors
in order to protect each other
