Complications and Arguments within Parental Investment
There are any different factors that play into this theory.

In humans specifically, there are situations that involve different variations of a father figure. There are situations in which, the father is involved, a step-father is involved, and no father is involved. Situations in which the father is involved, Ellison has conducted research that has concluded that daughters will go through puberty later compared to those with no father-figure in their life. Ellison also concluded that those with step-father figures primarily in their life, the daughters typically go through puberty in between the times in which those with no father and with a father would go through puberty. Those daughters with a higher "quality" and more involvement with their father figure will go through puberty later. The daughters with parents that have a higher "quality" relationship with each other also resulted in the daughters going through puberty later.

This all differs throughout different cultures. There are cultures in Asia that don't find it appropriate to hug and praise their children in certain ways while in America, they are more open to affection while there are still limitations. So how do you measure the "quality" of a relationship when it varies amongst cultures. There are also genetic factors that contribute to pubertal timing as well as the environment that the child has grown up in and the resources that have contributed to the growth and health of the child.
