Ten Thousand Jars of Fruit Flies in a Room at Columbia

Coming to Wonder Science on 3 December 2026.

In 1910 New York, on the high ground of Morningside Heights, a tall professor named Thomas Hunt Morgan, two young helpers and the custodian's nine-year-old daughter are trying to keep ten thousand milk-bottle jars of fruit flies alive in one cramped sixth-floor room at Columbia University. Among thousands of red-eyed flies, a single white-eyed male appears — and suddenly that one tiny fly must be guarded through spilled crates, soapy wash-tubs, a banana market under the elevated railway, a midnight walk home, a broken hand truck in the steam tunnels and a January blizzard that knocks out the heat. Saved in a rooftop glasshouse, the white-eyed fly's descendants let young Alfred Sturtevant unroll the first gene map across a library floor, and the team shows the world that heredity rides on chromosomes — before carrying their jars by steamer to a summer laboratory by the sea.
