His career was devoted to the processes whereby a new individual arises from parental reproductive materials.<ref>Baltzer, Fritz 1967. ''Theodor Boveri: The life of a great biologist 1862–1915''.

His other significant discovery was the [[centrosome]] (1888), which he described as the ''especial organ of cell division''. Boveri also discovered the phenomenon of [[chromatin]] diminution during embryoni
