Metcalf, Maynard Mayo (United States 1868-1940)
zoology, evolutionary biology

Metcalf was an invertebrate zoologist whose attention shifted over the years from an early interest in gastropods and tunicates to a later one in opalinid protozoans. Most of his publications concerned these groups' morphology, life history, and embryology, but he was also interested in the evolutionary implications of protozoology, especially as related to parasitism. In this connection he published a number of works exploring the use of host associations in understanding zoogeographic contexts. His researches turned him into a somewhat lukewarm supporter of the theory that certain now-fallen intercontinental land bridges might once have existed.
