Someone may physically resemble their parents, siblings, or even third generation ancestors. When a child is born, it is normal for him to learn naturally. No one teaches a baby how to crawl or how to react when he is hungry. However, talents, qualities and personalities develop through experiences. The environment in which people are raised can have a lasting effect or influence on the way they speak, behave, and respond to the things around them. According to Steven Pinker, behavioral genetics has shown that temperament emerges early in life and remains fairly constant throughout the life course, that much of the variation between people within a culture arises from differences in genes, and that in some particular genes can 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 what they are because they are taught to do so. This concept is well known as education in human behavior. In society there will always remain the doubt between are we born like this or do we behave according to life experiences? I firmly believe that education plays an important role in a child's upbringing and the decisions one will make in the future. First, humans learn from their environment and the behaviors of others. Secondly, culture plays an important role in people's lives. Finally, Jhon B Watson, a behaviorist, conducted an experiment inspired by Russian psychologist Ivan Pavlov to determine the classical condition in humans. Little Albert's experiment was conducted on a 9 month old baby who was shown a mouse to see his r...... in the middle of a sheet of paper...... I came to the conclusion that genetics are very important for personality development but they also need to determine how these genes are studied in order to determine a particular personality. “What scientists have found 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 dance or music. Whether a child will be musically inclined will be determined by how his or her genes interact with each other. Some parents would like to believe that creating a music-rich environment when the child is young will develop the child's talent for music. However, despite hypotheses like this, there is no evidence to demonstrate the long-term effects of growing up in a particular environment” (Pinker, 2003).
