The process by which living organisms adapt to changing environments is referred to as evolution, often driven by mechanisms such as natural selection. Through gradual changes over generations, species develop traits that enhance their survival and reproductive success in specific environments. Adaptations can be structural, behavioral, or physiological, allowing organisms to cope with challenges like climate shifts, food availability, or predator-prey dynamics. Understanding adaptation is fundamental to the study of biology and ecology, illustrating the dynamic relationship between organisms and their habitats.
