How development follows a definite and predictable pattern?

Development follows a definite and predictable pattern through established stages that individuals typically progress through, such as infancy, childhood, adolescence, and adulthood. These stages are characterized by specific biological, cognitive, and emotional milestones that align with age-related changes. Additionally, developmental theories, such as Erikson's psychosocial stages and Piaget's cognitive development theory, provide frameworks that highlight common trajectories and challenges faced at each stage. While individual experiences may vary, the overall pattern remains consistent across cultures and populations.
