CHRONICLE Life Devoted to Science (In Commemoration of the 100th Anniversary of the Birth of Barbara McClintock) transposons were found in bacteria, and, after another 17 years, in Drosophila. This succession of discoveries provided the basis for the concept of genome instabil- ity. An idea appeared on the “horizontal” transmission of genes under natural conditions. This has caused a impact on the theory of evolution. Why did McClintock and not another researcher discover transposable elements of the genome? Why were these elements ﬁrst discovered in maize, and only afterwards were similar phenomena found in bacteria and Drosophila, more “convenient” genetic objects? To answer these questions, we should year by year follow the development of McClintock’s studies and take into account their historical background. Barbara McClintock was born on June 16, 1902, in Hartford, Kentucky, United States, in a doctor’s family. She graduated from the College of Agriculture of Cor- nell University in Ithaca, New York, in 1923 and received her Ph.D. degree in botany there in 1927. Hav- ing been
