The niche construction perspective: a critical appraisal

Area of Science:

• Evolutionary biology
• Ecology
• Theoretical biology

Background:

• Niche construction involves organisms modifying their environments, with significant evolutionary and ecological impacts.
• Niche construction theory (NCT) posits that standard evolutionary theory undervalues niche construction and ecological inheritance.
• NCT proposes a revised evolutionary framework where niche construction is an evolutionary process equal in importance to natural selection.

Purpose of the Study:

• To critically evaluate niche construction theory (NCT) through a collaborative discussion between an NCT advocate and skeptics.
• To determine if niche construction qualifies as an evolutionary process.
• To assess whether NCT clarifies or obscures the role of natural selection in adaptation and the relative importance of niche construction versus natural selection.

Main Methods:

• A collaborative critical evaluation of niche construction theory (NCT).
• Discussion and debate on the definition and role of niche construction within evolutionary theory.
• Analysis of the internal coherence and accuracy of NCT literature regarding standard evolutionary theory.

Main Results:

• Identified key disagreements regarding whether niche construction is an evolutionary process.
• Debated the explanatory equivalence of niche construction and natural selection.
• Examined claims that NCT overstates niche construction's significance and its portrayal of standard evolutionary theory.

Conclusions:

• The evaluation highlights ongoing disputes in evolutionary theory concerning the reformulation of the neo-Darwinian synthesis.
• Disagreements stem from differing interpretations of niche construction's role and the definition of 'evolutionary process'.
• The study underscores the need for conceptual clarity in evolutionary biology, particularly regarding niche construction and ecological inheritance.
