“A father is known as a  man who exercises paternal care over other people.^[2][3]  Most fathers are naturally protective, supportive, and responsible and are able  to provide a number of significant benefits to themselves, their communities,  and their children.^[4]
Involved fathers offer developmentally specific provisions to their sons and daughters throughout the life cycle and are impacted themselves by their doing  so.^[5]  Active father figures have a key role to play in reducing behavior problems in boys and psychological problems in young women.^[6] For example, children who experience significant father involvement tend to exhibit higher scores on assessments of cognitive development, enhanced social skills and fewer behaviour problems.^[7][8][9] An increased amount of father–child involvement has also proven to increase a child’s social stability, educational achievement, and even their potential to  have a solid marriage as an adult. The children are also more curious about the world around them and develop greater problem solving skills.^[10] Children who were raised without fathers perceive themselves to be less cognitively and physically competent than their peers from father-present
families.^[11] Mothers raising children without fathers reported more severe disputes with
their child. Sons raised without fathers showed more feminine but no less masculine characteristics of gender role behaviour.^[12]

According to the anthropologist Maurice Godelier, the parental role assumed by human males is a critical difference between human society and that of humans’ closest biological relatives—chimpanzees and bonobos—who appear to be unaware of their “father” connection.^[13][14]“
