The "nature versus nurture" debate explores the relative contributions of genetics and environment to human development. Nature refers to the biological inheritance we receive from our parents, including traits like eye color and personality tendencies. In contrast, nurture encompasses the experiences, upbringing, and culture that shape an individual throughout life. Researchers study this interplay to understand how much of our behavior and characteristics are influenced by our DNA versus our surroundings. For example, a person's intelligence may be affected by both their genetic predispositions and the educational opportunities they receive in their family and community.
