Müller was an early investigator of
coevolution
In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well a ...

Müller was increasingly attacked by conservative circles in Germany for his ideas about evolution.

Yet, the Prussian state did not dismiss Müller.][ Daum, ''Wissenschaftspopularisierung'', pp. 72–74, 78–9.]
