Reciprocal altruism can be best explained with a model proposed by Robert Trivers in 1971. Trivers hypothesized that if one indi

vidual (A) pays some cost to help another individual (B), but the cost is recovered at some point in the future (when B helps A), then natural selection might favor behaviors that lead to this type of reciprocity. In which of the following situations is reciprocal altruism likely to occur?

Answer:

Reciprocal altruism is one of the altruism behaviors in which an individual organism helps in increasing the fitness of another organism by reducing the fitness of itself temporarily in expectation of the same behavior from another organism in the future later.

It takes place in the same set of organism partners which is a continuous interaction ion in stable groups of organisms.

Thus, the correct answer would be - an ongoing interaction in the same set of partners.

GaryK [48]

The answer here is D, and it's kind of obvious. But you probably already knew the answer and are just doing this for piece of mind.

(Okay, I read your question completely wrong, it's asking for which one of these has been solved isn't it?)

This is tough because all of these other than D have been figured out. Go with the methane atmosphere then.
