NATURE VERSUS NURTURE 2

Nature and Nurture influence human behavior

Introduction

The debate about nature versus nurture focuses on the comparative significance of a

human being’s inborn character traits, and the individual acquired behavior through nurtured

experiences. Human behavior is influenced by both nature through the genetic composition that

vary from one person to another, and behaviorism, which result from environmental factors.

According to Galton (2008), both heredity and environment have great influence on the

human beings’ social advancement. Human beings traits vary because of the inherited genes

from the parents, which results leads to the difference in the traits like intelligence. The genetic

composition of human being is reproduced in the consecutive generations, which make people of

the same generation behave in a similar way. When the biological structure of a person is

tampered with, it may result in behavior change. For example, if an individual has a brain injury,

the person’s demeanor changes from polite to aggressive.

Manipulation of certain genes in a human being results in behavior change. In a recent

study by Bulmer (2003), genes have been activated to manipulate traits, which adversely affect

the behavior. There is a correlation between traits and behavior. Certain traits are observed

because of the genetic composition, which result to the difference in behavior. This means

behaviors are influenced by traits, and traits are affected by certain composition of several genes.

The explanation of how nature influences behavior has been advanced to entail influences on

development, which result from prenatal and parental experiences.

The key diversity between the impact of genes and environmental factors can be

observed in population variance. The focus from an individual to population sample underscores

the fatal difference between nature and nurture. The environment influences a person’s

personality largely although the traits in that person must be involved. Nurturing does not only

entail the care the mother gives to a child, but it is any contemporary influence on human

behavior anchored in political and social-economic status. Factors such as social norms, culture,

faith, and attitudes shape how people behave (Triandis, 2009).

The most pertinent way to determine the influence of genetic composition and

environment on a certain trait is depicted in a case study of twins. In the case study, the two

twins were raised in a different environment. From the study, the following deductions were

made: the twins had the same genetic composition, but had different behavior because of

difference in the environment. The twins shared a similar trait of intelligence, but they liked

different music, food, clothing, and religion. This shows both environment and genetics play a

big role in the development of human behavior (Triandis, 2009).

Conclusion

Nature and nurture both play a key role in the behavior of people. It is through nature

individuals traits are formed, and then behaviors are shaped by environmental factors. Nature

entails genetic composition of a person that shows distinct human traits. Consequently, nurture

encompasses the influence of environmental factors on human traits, which result to the

difference in behavior.
