The Correlation Between Paternal Investment and Daughters' Sexual Debut

In the context of todays society, there is a potential connection between investment of father and daughters first time experiencing penetrative sex, so we propose an experiment, questioning how the paternal investment predicts the age of sexual debut in daughters. Two surveys are designed for mother to report paternal investment, dividing fathers into always present, partially absent, always absent, and for daughter to report their first time experiencing penetrative sex. Since sexual behaviors are the main approach of reproduction, which evolutionary psychology pays lots of attention on due to its connection to human evolution and natural selection, we decide to use evolutionary psychological perspectives to explain and discuss our results. As this experiment proposal will not yield data, positive correlated and negative correlated results are discussed separately, using different theory to explain the findings.
