Consider the following argument:

Question

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

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

Answer 1

The argument states that altruistic behavior in groups of related individuals is likely driven by kin selection due to shared DNA. To weaken this argument, we would need evidence suggesting that altruistic behavior does not align with kinship or that it occurs more frequently among individuals who are not closely related.

Among the provided options, the most effective evidence to weaken the argument would be:

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

This evidence directly contradicts the argument by indicating that altruistic behavior is more prevalent among individuals who are not closely related, thus challenging the notion that kin selection is the primary driver.
