At the Deathbed of Darwinism

Eberhard Dennert gathers objections to Darwinian natural selection in a series of papers presented in this English translation of 1904. The opening separates the broad idea of common descent from the proposed mechanism of small useful variations preserved through the struggle for life. Dennert builds his argument around the views of named scientists, asking how adaptations arise and what evidence supports gradual changes from one species to another.

A discussion of butterflies gives the controversy a concrete focus. Leaflike wings, recurring patterns and changes of color become evidence in Eimer's case for development shaped by climate and nourishment. Across the chapter headings, botanical experiments, fossil records and competing theories of organic growth connect biological explanation with philosophical and religious concerns. Readers interested in the history of evolutionary debate can examine how Dennert selects testimony and frames scientific disagreement in support of his own position.
