Daniele Rosa (1857–1944) was an Italian invertebrate zoologist.[1]
Rosa was born in Susa, Piedmont. He graduated from the University of Turin. He is most well known for his orthogenetic evolutionary theory known as hologenesis ("ologenesi" in Italian).[1] His theory proposed that evolution is internally driven.[2][3] Science historian Peter J. Bowler has noted that Rosa's theory of hologenesis was "ignored or dismissed by the supporters of the modern synthesis".[4] His orthogenesis theory is considered to be discredited. However, Rosa contributed valuable research to the fields of biogeography and cladistics.[1][5] His research influenced the biogeographer Léon Croizat.[6]
