Why developmental niche construction is not selective niche construction: and why it matters

Area of Science:

• Evolutionary biology
• Developmental biology
• Genetics

Background:

• Niche construction is recognized as a key evolutionary process.
• Organisms interact with and construct their environments, influencing selection and generating variation.
• Parental effects demonstrate non-DNA-mediated offspring influence.

Purpose of the Study:

• To formally introduce and define Developmental Niche Construction (DNC).
• To differentiate DNC from traditional niche construction theory.
• To explore the evolutionary significance of DNC.

Main Methods:

• Literature review and conceptual synthesis.
• Analysis of existing evidence for exogenetic inheritance and parental effects.
• Theoretical framework development for DNC.

Main Results:

• DNC encompasses mechanisms for transgenerational transfer of developmental resources.
• DNC highlights the organism's active role in its developmental environment, distinct from its selective environment.
• The concept provides a formal name for exogenetic inheritance phenomena.

Conclusions:

• DNC offers a comprehensive framework for understanding environmentally induced heritable variation.
• DNC expands evolutionary theory by incorporating the organism's active role in shaping its developmental trajectory.
• Further research into DNC mechanisms is crucial for understanding evolution.
