The article examines the evolutionary dynamics of intelligence, highlighting that greater cognitive ability is not always advantageous for survival. Using examples such as parasitic barnacles (genus Sacculina), fruit flies, pheasants, koalas, and various parasites, it illustrates how some species have evolved reduced brain size or cognitive capacity as adaptive strategies suited to their ecological niches. Research shows that intelligence can entail significant energetic costs and trade-offs with longevity, reproduction, or survival, and in certain environments, simpler or less flexible behavior may be more beneficial. These findings challenge the common assumption that evolution inherently favors increased intelligence, emphasizing that evolutionary fitness depends on context rather than cognitive complexity.
