Niche construction, sources of selection and trait coevolution.

Area of Science:

• Evolutionary Biology
• Ecology
• Behavioral Ecology

Background:

• Organisms actively modify their environments, a process termed niche construction.
• Niche construction influences ecological dynamics, natural selection, and inheritance via ecological legacies.
• The role of niche construction in directing adaptive evolution requires further elucidation.

Purpose of the Study:

• To propose niche construction as a driver that initiates and directs selection.
• To illustrate how niche construction imposes a consistent bias on selection, co-directing adaptive evolution.
• To position niche construction relative to artificial and natural selection.

Main Methods:

• Conceptual framework comparing niche construction to artificial selection.
• Analysis of how niche construction generates evolutionary bias.
• Formulation of testable predictions regarding evolutionary responses.

Main Results:

• Niche construction acts as a directed and sustained source of selection on constructors and other species.
• It occupies an intermediate position between artificial and natural selection.
• Predictions include reduced variance in natural selection responses, multi-trait coevolution, and a positive link with biodiversity.

Conclusions:

• Niche construction is a significant evolutionary force that actively shapes adaptive trajectories.
• Recognizing niche construction offers a more comprehensive understanding of evolutionary biology.
• Further research should focus on the diverse properties of all selection sources, including niche construction.
