Daniele Rosa

Daniele Rosa (1857–1944) was an Italian invertebrate zoologist.

He is most well known for his orthogenetic evolutionary theory known as hologenesis ("ologenesi" in Italian).

[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".

However, Rosa contributed valuable research to the fields of biogeography and cladistics.

[1][5] His research influenced the biogeographer Léon Croizat.
