Which developmental process emphasizes the role of biology over environmental influence?

The emphasis on biology over environmental influence in the developmental process is most prominently captured by maturation. Maturation refers to the natural growth and development that occurs as a result of biological processes. This concept highlights the sequence of development that is programmed into an individual’s genetics, where certain abilities and behaviors emerge at specific stages regardless of environmental factors.

For instance, physical growth, such as the development of motor skills in infants, follows a biological timetable that is largely independent of external circumstances. While environmental influences can shape experiences and learning, maturation is centered on the innate biological clock that dictates when certain developmental milestones are reached. This is why it is considered the process that primarily emphasizes biological factors in development.
