History of Behavioural Genetics
From Thomas Hunt Morgan to Woo Jae Kim

"The pedigree is skewed to show how the Drosophila renaissance in the 1980s descends from the Columbia Fly Room. Descendants who founded schools in other organisms are also shown, but their ‘heirs’ are not (unless they move back into flies). Individuals are listed only once. Thus, interactions within labs can be deduced but not the spread of ideas and techniques via the movement of postdocs. The pedigree is divided vertically into filial generations and horizontally into sublineages. At the top left are the ‘triumvirate’ who ‘invented’ Drosophilia as a genetic organism, Morgan and his two graduate students Sturtevant and Bridges. All three moved to Caltech when Morgan founded the Division of Biology (1928), and the pink band contains Morgan’s direct line, which formally descends through Sturtevant. ‘F2’ graduate students are those selected by Sturtevant himself (A History of Genetics. New York: Harper and Row; 1965), plus Lindsley. Delbrück is also on Sturtevant’s Caltech pedigree and illustrates the movement into ‘lower’ organisms in the 1930s–1940s, followed by the move back into flies in the 1960s–1970s. (Delbrück was a cofounder of the ’phage group; Benzer founded Drosophila neurogenetics.) The beige and yellow bands also descend from Columbia. Muller, a semi-detached member of the Fly Room, moved often and founded several schools; only his Texas and Edinburgh heirs are shown here. Stern was the most successful of the Fly Room postdocs: he and Hadorn (an amphibian embryologist who moved into flies via a postdoc with Stern) pioneered Drosophila developmental biology. In the lowest band are two Caltech postdocs: Dobzhansky founded a school of Drosophila population genetics at Columbia; Beadle ‘invented’ Neurospora as a tool for biochemical genetics and succeeded Morgan as head of Caltech’s Division of Biology. Two of Beadle’s heirs moved back into flies: Mitchell in the 1950s and Hogness in the 1960s. The Hogness laboratory pioneered Drosophila molecular biology and launched the Drosophila renaissance." Winchester, Guil. "Pedigree: The Morgan lineage."

If you want to know more about the history of behavioural genetics, you can read the book A Great Biologist and His Quest for the Origins of Behavior> written by Jonathan Weiner. This book "recounts the story of the work of many scientists but especially that of Seymour Benzer, who did basic research using genetic dissection, an approach that he “had started . . . with single genes . . . working up to behavior” in a fly room at the California Institute of Technology (Caltech)."
