NOTE

Exploring Mutations, Fitness, and Information in Evolutionary Biology

Mutations in organisms act as measurements of the environment, with beneficial mutations being adjustments to thrive in specific conditions while deleterious mutations reduce fitness and are eliminated. This continuous process of mutation leads to an increase in information within an organism over time, forming the law of increasing information in evolution. While the natural selection process generally increases information, environmental changes or factors like recombination can lead to a loss of information. Complexity in organisms is directly related to the amount of information they contain, as complexity is essentially useful and intricate information. Therefore, the complexity in evolution increases with time, reflecting the increasing information within organisms driven by the natural selection process.
