Phenotypic Evolution

Phenotypic evolution refers to the gradual changes in observable traits of organisms over generations, such as size, shape, color, or behavior. These changes occur because of genetic variations within a population, which are passed to offspring. When certain traits offer advantages for survival or reproduction, they become more common over time. This process helps species adapt to their environments, shaping their physical and behavioral characteristics through natural selection. Essentially, phenotypic evolution is how living beings change their outward features and behaviors across generations to better fit their surroundings.
