The fruit fly is the most-studied animal in scientific history. Six Nobel Prizes have been awarded for research using Drosophila — including the foundational 1933 prize for chromosome theory. Around 75% of human disease genes have a Drosophila equivalent. A single 3 mm fly has driven a century of biology.

Field guide
Drosophila melanogaster, the common fruit fly, is the most-studied animal in the history of biology. Beginning with Thomas Hunt Morgan's 1910 discovery of the white-eye gene at Columbia University, Drosophila has been the foundational model organism for genetics, developmental biology, neuroscience, and behavior. Six Nobel Prizes in Physiology or Medicine have been awarded for Drosophila research: 1933 (Morgan, chromosomes), 1946 (Muller, mutations), 1995 (Lewis, Nüsslein-Volhard, Wieschaus, embryonic development), 2004 (Axel and Buck, smell), 2011 (Hoffmann, immunity), 2017 (Hall, Rosbash, Young, circadian rhythms). About 75% of human disease genes have a recognizable Drosophila ortholog — Alzheimer's, cancer, Parkinson's, diabetes, addiction research all use fruit flies. The species' short generation time (10 days egg-to-adult), small genome (4 chromosomes), prolific reproduction (~100 eggs/day per female), and ease of culture make her ideal. Drosophila also has surprising behavioral complexity — they sleep, dream, become addicted to alcohol, court via species-specific 'songs' (males vibrate wings at distinct frequencies), and learn associative tasks.

Cultural file
Drosophila is a foundational figure in 20th-century science history. The 'fly room' at Columbia University (1910s-1920s) is recognized as one of the most important laboratory spaces in biology. Modern Drosophila research drives a $3+ billion annual research economy across thousands of labs worldwide.
