In the field of biology, researchers typically focus on a select few model organisms rather than studying the millions of species on Earth. Model organisms are chosen for their quick reproduction, ease of laboratory maintenance, and relatively simple genetic characteristics. This focus enables scientists to uncover vital biological processes. Among these organisms, fruit flies and nematodes hold particularly symbolic roles. Fruit flies, although small and seemingly insignificant, played a key role in transforming modern genetics.

The story of fruit flies in genetics began in the early 20th century when American biologist Thomas Hunt Morgan started studying them in his lab at Columbia University. This small space, known as the 'Fly Room,' became a groundbreaking site for genetic research. Morgan and his students discovered that genes exist on chromosomes and developed techniques for mapping genes. Their pioneering work laid the foundation for modern genetics, which culminated in Morgan receiving the Nobel Prize in Physiology or Medicine in 1933.

A recent book by Kim Woo-jae explores the history and significance of fruit fly research in a captivating manner. Unlike typical science history texts, Kim’s work delves into how fruit fly studies shaped contemporary biology's culture and research methodologies. The Fly Room is portrayed not just as a laboratory, but as a birthplace for modern biology, demonstrating how significant insights into universal life principles were uncovered through the study of this small insect.
