چکیده
Edmund Beecher Wilson [4] contributed to cell biology, the study of cells, in the US during the end of the nineteenth and the beginning of the twentieth centuries. His three editions of The Cell in Development and Inheritance [5] (or Heredity [6]) in 1896, 1900, and 1925 introduced generations of students to cell biology. In The Cell, Wilson described the evidence and theories of his time about cells and identified topics for future study. He helped show how each part of the cell works during cell division and in every step of early development of an organism. Developmental biologists trained in the mid-twentieth century reported Wilson?s text as their foundation for understanding biology, including about how cells, development, heredity, and evolution [7] interact. Wilson considered cells as the center of all biological phenomena.
