Wilson, is credited as America's first cell biologist, in 1898 he used the similarity in embryos to describe phylogenetic relationships, by observing spinal cleavage in molluscs, flatworms and annelids he concluded that the same organs came from the same group of cells, he concluded that all these organisms must have a common ancestor. He also discovered the chromosomal XY sex-determination system in 1905, Nettie Stevens discovered the same in 1905, too. Professor Wilson published many special papers on embryology, and served as president of the American Association for the Advancement of Science in 1913.
