Such restriction has been shown to reduce risk factors for several chronic diseases in animals and humans and to increase life span in rats, mice, fish, flies, worms and yeast.

Though RNA editing has been observed before, in animals ranging from humans to nematode worms, this is the first time an edit has been tied to a clear evolutionary difference caused by a feature of the environment in this case ambient temperature.
