Someone can physically resemble their parents, siblings, or even third-generation ancestors. When a baby is born, it is common to learn naturally. No one teaches a baby how to crawl or how to respond when hungry. However, talents, qualities and personalities develop through experience. The environment in which people grew up can have a lasting effect or influence on the way they speak, behave, and react to the things around them. According to Steven Pinker, behavioral genetics has shown that temperament emerges early in life and remains relatively constant throughout life, that much of the variation between people within a culture comes from genetic differences, and that , in some cases particular genes may be linked. to aspects of cognition, language and personality (2). Researchers believe that the origin of behaviors lies in DNA genes or even animal instincts, a concept known as the nature of human behavior. Other researchers believe that people are the way they are because they were taught to be. This concept is well known as the culture of human behavior. In society there will always be doubt between Are we born this way or do we behave according to life experiences? I strongly believe that education plays an important role in a child's upbringing and the decisions one makes in the future. First, humans learn from their environment and the behaviors of others. Second, culture occupies an important place in people's lives. Finally, John B Watson, a behaviorist, conducted an experiment inspired by Russian psychologist Ivan Pavlov to determine the classical condition in humans. The Little Albert experiment was carried out on a 9 month old baby who was shown a rat how to see his middle of paper...... we came to the conclusion that genetics are very important for the development of personality but even they must determine how these genes are studied in order to determine a particular personality. “What scientists have discovered is that there does not appear to be a single gene for a particular trait, but that genes show their effects by working together in complex combinations. For example, there is no single gene for dancing or music. Whether a child is musically inclined will be determined by how their genes interact with each other. Some parents would like to believe that creating a music-rich environment while a child is young will develop their talent for music. However, despite such assumptions, there is no evidence demonstrating the long-term effects of growing up in a particular environment” (Pinker, 2003).
