If an alien stumbled across that data they might surmise that rodents "rule" this planet, followed by fruit flies as their symbiotes/slaves/pets, followed by everyone else. However, if they had a moral code like ours they might instead surmise that rats, mice, and flies are viewed as expendable to the actual "rulers" of the planet and that these have an aversion to slicing themselves up for science. So they might conclude the rulers to be one of the primates given the existence of three close species: human/chimp/baboon in one family (monkey).
