Developmental plasticity refers to the ability of an organism to change and adapt its development in response to environmental influences. This phenomenon allows organisms, including humans, to modify their physical and behavioral traits based on experiences during critical periods of growth. For example, a child's brain can form new connections based on learning and social interactions. This adaptability is crucial for survival, as it enables species to thrive in varying conditions. Factors such as nutrition, stress, and social environments can significantly impact developmental outcomes. Understanding developmental plasticity helps researchers explore how early experiences shape lifelong health and behavior.
