Inhibiting variation stifles evolution from "summary" of The Evolution of Everything by Matt Ridley
The concept that inhibiting variation stifles evolution is a fundamental principle in the study of how complex systems evolve over time. Evolution is a process of constant change and adaptation, driven by the generation of new variations in traits and characteristics. These variations arise through a combination of random mutations and environmental influences, leading to a diverse range of possibilities within a population. When variation is restricted or limited in some way, such as through artificial selection or strict environmental constraints, the potential for evolutionary change is also constrained. This limitation on variation can prevent populations from adapting to changing conditions or exploring new opportunities for growth and development. Inhibiting variation not only stifles the ability of a population to evolve in response to external pressures or challenges but also limits the overall diversity and resilience of the system. A lack of variation reduces the pool of potential traits available for selection, making it more difficult for a population to survive and thrive in a changing environment. In contrast, environments that allow for a high degree of variation provide abundant opportunities for experimentation and innovation. Populations with greater genetic diversity are better equipped to adapt to changing conditions, as they have a wider range of traits to draw upon in response to challenges. By inhibiting variation, we limit the ability of populations to explore new possibilities and adapt to changing circumstances. Evolution is a dynamic process that relies on the generation and selection of diverse variations to drive change and growth over time. Without this essential ingredient, the evolutionary potential of a system is severely limited, leading to stagnation and decline.
