allows the father to be able to spend more time with the infant and really create a bond with them. This makes a father's role in child upbringing an important aspect of the Aka culture. The Aka foragers in the Central African Republic do not hunt with bows. Their main source of hunting is through nets. In Hillary N. Fouts cross-cultural research, she had statistical data that supported the claim that different roles in foraging populations had an impact on the amount of time a father spent with their children. Fouts took different foraging populations in Africa and compared their type of hunting and the percentage of time these fathers were seen holding their child. Her first foraging group was the Aka population. They were a net hunting group that held their children aged 1–4 months 22% of the day, held their children 8–12 months 11.2% of the day, and held their children 13–18 months 14.3% of the day. The other net hunting population was the Bofi. They had fathers hold babies aged from 36-47 and 48–59 months for 5.4% of the day. In contrast, the foraging groups that participated in bow hunting had fathers hold babies for significantly less time. The Hadza foraging population had fathers hold babies from the ages 0–9 months for only 2.5% of the day. The other bow hunting foragers, the !Kung, had fathers hold babies from 0–6 months for 1.9% of the day and babies 6–24 months 4.0% of the day. This statistical data shows that different roles in a society influences how much time the father spends holding and interacting with his children. This is important because it shows that each culture is different regarding father upbringings and father bonding. Legal paternity United States In the U.S., legal paternity is presumed for the husband of the mother unless a separate action is taken; an unmarried man may establish paternity by signing a voluntary recognition of paternity or by taking court action. Paternity may also be established between a man and a younger person, commonly in adoption, without the two being biologically related.
