Which piece of evidence best supports the hypothesis that the evolution of altruistic behavior is driven by kin selection? A hippo is observed saving an antelope from an attack by an alligator. A cuckoo bird hides its own eggs in the nest of another bird species. A meerkat protects the offspring of its sister from an attack by hawks. A male gorilla helps protect his offspring from an attack by a tiger.
Hamilton's Rule describes the relationship between cost and relationship in the evolution of altruistic behavior. Which of the following do not support Hamilton's rule: In colonies of Naked Mole Rates, only one female is reproductive. Cattle egrets sometimes kill their siblings. Wood mouse sperm will sacrifice themselves to assist a "sibling" sperm to fertilize an egg. O A Prairie Dog trills in response to an oncoming predator and is more likely to be eaten because it exhibits this behavior.
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? Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other Data showing that food gifts are given more common among family members than between unrelated individuals in a group 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 the more frequent an allele of a gene occurs in a population, the more likely that population performs altruistic behaviors
You document altruism in an animal species that you are studying: female zebras running at the back of the group, closest to the pursuing predator, as the group runs to escape a predator. Both kin selection and reciprocal altruism can explain this behavior. What piece of evidence would support the hypothesis that it's kin selection?
