Nature versus nurture has become one of the most heated debates of the 21st century. It is more aligned with the internal and external factors that make up the behavior of human beings. Internal factors are innate and perceived to be genetic in origin, as opposed to external factors which are influenced by the environment and experiences of individuals. However, researchers from different fields have conducted research on the relationship between nature and nurture without success, which has created gaps for further research on this topic. This context will review academic sources to examine their bone of contention on this issue and criticize them for their shortcomings in approaching this topic. In Bryner Jeanna (2006) in her book, “Nature vs. Nurture: Mysteries of Individuality Unraveled” published by Live Science, crucial questions arise about whether certain events are based on genetic inheritance or are the result of simple coincidence. Elements such as talent, intelligence, and personality are at the forefront of their discussions because they are inherited or acquired through exposure and environmental experience (Bryner). According to her, these questions have posed many challenges to philosophy, psychology and genetics. To verify their claims, twin studies were used. The aim of the study was to determine whether genes play an important role in influencing certain common behaviors such as addiction, violence and talent. Additionally, the possibility that genes may contribute to diseases has also been investigated. Through research, it was realized that smoking was influenced by a gene known as CYP2A6, which varied among individuals (Bryner). Along the same lines, alcoholism also...... middle of article......tp://www.livescience.com/4168-nature-nurture-mysteries-individuality-unraveled .htmlMullen, John. “Nature, culture and individual change. » Cambridge Center for Behavioral Studies, 34 (2006): 1-17.
