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.
Scientists from Trinity College Dublin have unearthed a universal thermal performance curve (UTPC) that seemingly applies to all species and dictates their responses to temperature change. This UTPC essentially shackles evolution ...
