It is expected that closely related organisms are more likely to show similar ecological interactions than less related ones. But this has been tested only for certain types of interaction, and in a restricted set of taxa. Now interaction networks have been constructed for 116 different clades of related organisms, across the entire tree of life, and including all types of interaction. The results reveal significant conservatism across the board, including both specialist and generalist species.
