Nature  vs Nurture debate.

Explanation:

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.
