Based on kin selection Bob is most likely to help his brother Ralph.
Kin selection is a sub-theory of natural selection that states organisms tend to help those genetically related to them (relatives). In humans, this theory implies:
- The closest a person is in terms of genes, the most likely you are to help him/her.
- Helping relatives can sometimes decrease our chances to survive while increasing the survival chances of that person.
- We are less likely to help people that are not genetically related to us such as colleagues, friends, classmates, etc.
Based on this, Bob is most likely to help his brother rather than his step-sister, cousin, or best friend. This is because in terms of genetics Bob and his brother are very close.
