Researchers have been in dispute for many centuries about whether nature or nurture has a stronger influence on early human development. Nature is inherent traits from birth and Nurture is one's environment (physical, cultural, social, and familial) plays in one's physical and psychological identity. This essay will examine the degree to which nurture or nature influence early human development. Nurture strongly influences early human development, for many reasons. According to Locke (17th.Century), the mind of a new born infant is a “blank slate”. As the baby experiences and interacts with his world through his or her senses the knowledge become built and is written down on the slate. Examples: seeing, hearing, feeling, touching,

Speech according to (Kagan, 1979) motivates infants and toddlers to learn to speak a word or a sentence but not until reaching a certain level of neurological development. Example: no infant speaks a sentence within less than a year old. Nature, alternatively some researchers believe that it also influences early human development. Charles Darwin’s (1859) theory of evolution highlights on the fact that the biological basis of human development affects heredity.
At the moment of conception, our genes determine our personal characteristics which programs our growing cells so that we develop into a person rather than a chimpanzee. Example: our sex, color of our skin, eyes, hair and general body size.
Genetic determinants are expressed in development through the process of maturation. Example: fetus developing in the mother’s body follows an orderly sequence depending on the stage of growth.
All children go through the same process and same sequence of motor behaviors in the same order. Example: rolling over, crawling and sitting without support.
Practice and extra stimulation can also accelerate the appearance of motor behaviors. Example: a group of infants were given stepping practice for a few minutes several times a day began walking five to seven weeks earlier than babies who had not had this practice.
Through the track of normal development, all infants learn to speak, but not until they attain a certain level of neurological
