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.<u>Although environmental factors may influence  this developmental stages, the exact mechanism of occurrence is constant and fixed.</u>
<u />
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.
<u>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.  </u>
 
        
             
        
        
        
Answer:
This type of brain plasticity is known as neuroplasticity.
Explanation:
Neuroplasticity allows neurons to regenerate (anatomically and functionally), which allows them to form synaptic connections. Neural plasticity means the ability of the brain to recover and restructure. This is a characteristic of the adaptive potential of the nervous system allowing the brain to recover from disorders, and can also reduce the negative effects of diseases such as multiple sclerosis, Parkinson's, Alzheimer's disease, etc.

Thomas Malthus was an English scholar and cleric who was known for his views in political science and demography (study of population). His views suggested that population would outpace food the supply of food and that the only vital parameters of population growth were famine, war and diseases. His writings on demography were influential in shaping the economic thinking.
