Selfish genetic elements and the gene's-eye view of evolution

Area of Science:

• Evolutionary Biology
• Genetics

Background:

• The study of selfish genetic elements has seen significant advancements.
• The gene's-eye view has been a dominant framework for understanding these elements.
• Criticism of the gene's-eye view has led to alternative frameworks, such as multilevel selection.

Purpose of the Study:

• To trace the historical association between selfish genetic elements and the gene's-eye view.
• To compare the gene's-eye view with alternative conceptual frameworks.
• To explore the implications of selfish genetic element research for broader evolutionary concepts.

Main Methods:

• Historical analysis of the study of selfish genetic elements and the gene's-eye view.
• Comparative analysis of different conceptual frameworks (gene's-eye view vs. multilevel selection).
• Case studies using transposable elements and major evolutionary transitions.

Main Results:

• The gene's-eye view, while influential, faces challenges from alternative models.
• Different evolutionary models highlight distinct facets of selfish genetic element evolution.
• Empirical studies on selfish genetic elements inform debates on adaptationism and fitness maximization.

Conclusions:

• A plurality of perspectives is essential for a comprehensive understanding of selfish genetic element evolution.
• Selfish genetic elements challenge and refine core concepts in evolutionary theory, including the gene's-eye view.
• Continued research on selfish genetic elements has broad implications for understanding evolutionary processes.
