Biologists focus on heredity in human development, whereas sociologists focus on learning, socialization, and culture. This difference of opinion is called ___________.

Development in human is inborn.The stages of development is dictated and directed by expression of genes encoded by the DNA.Therefore physiological and biochemical interpretations of these DNA dictates is known as human development. it is a fixed mechanisms which is fastest at childhood,and progressively slower at advanced stage.Although environmental factors may influence this developmental stages, the exact mechanism of occurrence is constant and fixed.

Nuture concept believe that, human development is as a result of societal and cultural factors in the environment, and the progression of the development is due to the influences of theses factors on human perception of life. Thus Human development is acquired through life exposure and experiences.They are therefore dynamic, and not static, but fluctuates based on level of exposure in the environment.

However, both concept interacts with one another to ensure an holistic human development. Generally it is the interaction of the environment with genetic that explains the concept of natural selection and evolution of human race.
