1. Personality and Your Parents Cesar Monzon Humans choose mates based on attractiveness or some level of fitness(not just physical). The personality traits you inherited have been given to you through the process known as selection and evolution. (Nettle, 2006)

2. Personality Evolution There are many different personality evolution perspectives. One perspective involves a trade off of positive and negative aspects for each variation of behavior(Nettle, 2006). What purpose does your personality serve? Extroversion is related to number of sexual partners but at the same time results in an increase in risky activity with other individuals or the environment(Nettle, 2006). Neuroticism has benefits such as an increase in speed of detecting threats as well as increasing competetativeness. The negatives of such a trait are obvious stress, anxiety and overall worse physical health(Nettle, 2006). Cesar Monzon

3. Openness-related to artistic creativity which in turn attracts more mates. Prone to psychosis type disorders(Nettle, 2006). Conscientiousness- sticks to long term plans, delays gratification. Being overly conscientious can be obsessive lower overall fitness by reducing mating opportunities(Nettle, 2006). Agreeableness- Related to trust and cooperation with others, less exposure to violence and more harmony. Lack of agreeableness correlated with antisocial personality disorder(Nettle, 2006).
