Biological anomalies refer to unusual or atypical variations in the structure or function of living organisms. These can occur at various levels, from genetic mutations in DNA to physical differences in anatomy. Such anomalies can arise naturally or due to environmental factors, and they may affect an organism's health, behavior, or development. Examples of biological anomalies include polydactyly, where an individual has extra fingers or toes, and albinism, a condition characterized by a lack of pigment in the skin, hair, and eyes. While some anomalies may pose health challenges, others can provide unique advantages in certain environments.
