Biologist Edmund Beecher Wilson studied the role of heredity in cellular development and, working independently of Nettie Stevens, both scientists co-discovered the chromosomal basis of sex, in concurrent papers published in 1905. Their work effectively settled the long scientific debate over whether sex is determined by heredity or by environmental factors.

Wilson, who was born before Darwin's Origin of Species was published, is generally cited as America's first cellular biologist. He wrote extensively on cellular structure and general biology, and stressed that biology is comprised of different factors, including embryology, evolution, and heredity. He headed Columbia University's Zoology Department in the early decades of the 20th century, where Wilson, with his friend Thomas H. Morgan and his student Hermann J. Muller, helped establish the modern science of genetics.
