They discovered that children adopted by foster parents tend to exhibit the traits of their respective foster parents significantly more than those of the biological parents (Exeter). Genes given to offspring by the birth parents are not extremely powerful in the sense that personality cannot be developed solely from them. For example, a parent can pass on a high-risk emphysema gene due to smoking cigarettes heavily. However, if this specific person never smokes cigarettes throughout their life, which deals with that person’s environment or nurture in this case, then he or she will not develop emphysema considering that most traits only occur in specific environments. Consequently, the personalities of humans are very flexible and susceptible to change considering the fact that surroundings around humans change very often. If the surroundings did not change, it would be easier to support the Nature Theory and stagnant surroundings would portray the idea that personalities stem from genes alone. In addition, in the book of Frankenstein, the monster watches the family he lives next to as mentioned above. He notices that the family cares for each other and loves each other very much and this makes him want a monster companion and makes him want acceptance, specifically from his creator since the family …show more content…
Many Nature Theory activists will disagree, however. Nature Theory supporters tend to bring upon the argument that anxiety, depression, and increased stress or hypertension only stems from genetically obtained cortisol levels and that imbalanced cortisol levels are received from the offspring’s parents. Dr. Audrey Tyrka, M.D. PhD, conducted a study regarding the interaction of complex neurobiological mechanisms in coherence with traumatic experiences resulting in depression and anxiety. Cortisol, also referred to as the stress hormone, is the main component when it comes to these illnesses; people who have depression and anxiety have lower than average cortisol levels in almost all cases. The receptor for this hormone acts as a receiver for messages that are sent between cells during times of stress. During stress response, corticotrophin-releasing hormone (CRH) stimulates the pituitary gland to release another hormone, adrenocorticotropic, which induces the release of cortisol from the adrenal cortex. In the context of everyday stress, cortisol release helps the body to respond adaptively by releasing energy from storage cells (Tyrka). However, this stimuli and response system in nature is triggered by outside influences in nurture that lead to stress such as abusive relationships, bullying, working long hours, going to school, and the
