Fruit flies remember their larval diet, which influences their longevity

Fruit flies that eat less protein as larvae tend to have a shorter lifespan as adults due to their reduced ability to produce proteins. This is based on research on the Drosophila melanogaster species, which found that flies that were fed a diet low in protein had lower levels of protein production as adults. The study suggests that the protein intake during the larval stage affects the development of adult flies.
