Biological adaptation is the evolutionary process through which heritable traits that enhance an organism’s fitness become more prevalent in a population over generations under specific environmental conditions. It operates primarily via natural selection acting on genetic variation, including mutations, recombination, and gene flow, and is constrained by developmental, genetic, and phylogenetic factors. Adaptations can be morphological, physiological, or behavioral and are typically characterized by increased survival or reproductive success in a given niche. The process is dynamic and context-dependent, such that traits advantageous in one environment may be neutral or deleterious in another, contributing to diversification and speciation.
Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species. However, ...
