# Drosophila melanogaster *Drosophila melanogaster*, the common fruit fly, is a widely used [[Model Organism]] whose short lifecycle and tractable genetics support research into aging, fertility, metabolism, and stress response. ## Notebook evidence PDF page 13 of [[Scanned_20260730-1825]] asks whether an internship involving “flies,” life extension, fertility, and the University of South Alabama concerned fruit flies. The combined vocabulary strongly matches that institution's Drosophila longevity research lineage. ## Evidentiary boundary The research-cluster identification is strong; the daughter's identity, exact laboratory, internship dates, and species remain unresolved. Fly results identify mechanisms for further study and are not direct evidence of human life extension. ## Source - [[Scanned_20260730-1825]], PDF page 13.
