The theoretical status of ‘niche construction’ in evolution is intensely debated. Here we substantiate the reasons for different interpretations. We consider two concepts of niche construction brought to bear on evolutionary theory; one that emphasizes how niche construction contributes to selection and another that emphasizes how it contributes to development and inheritance. We explain the rationale for claims that selective and developmental niche construction motivate conceptual change in evolutionary biology and the logic of those who reject these claims. Our analysis (...) shows how the contention arises from alternative assumptions regarding the causal independence of the processes that generate variation, differential fitness and inheritance.
