the documentary “Babies” took four children from different ethnic and cultural backgrounds from different parts of the world; Ponijao in Namibia; Bayarjargal in Mongolia; Mari in Tokyo and Hattie in San Francisco, following them from birth to their first birthday. Although there was no narration from the director, it was clear what the story was about. These children gave us a side-by-side glimpse into their lives, showing us the ways in which they are the same, even culturally, despite how they were raised. Likewise, how much they evolved based on different selection pressures in their culture. Although these children, through their culture, have developed their own identity, there are times when they still show how similar they are. What these children have in common, no matter where they are in the world, are their developmental stages. All four children reached a milestone in their lives at about the same time. They rolled, crawled and walked all the same age. They laughed, cried, pooped and played the same way. They show similarities in game development; you see their playful interactions with others around them, whether it's their parents or other children around them or when they are left to play alone. We saw Mari get frustrated while trying to insert a spindle into the hole of a record; I saw Bayar trying to grab a roll of toilet paper which he manages to unroll, once he grabbed it, he started biting it and seems to be having fun doing it. We observed how these children showed their curiosity about the things around them and also their curiosity about self-discovery. We saw Ponijao looking under the loincloth to see... the center of the paper... being a common practice in Ponijao and Bayar culture. But if we look beyond all these aspects of their lives, we will see the happiness and contentment on the faces of those children. We see the expression of the mother's love and affection towards the child. We see that mothers take great care of their children; they sang to them, talked to them and held them close. Other ways in which children show the impact of cultural selection pressures are the ways in which they interact with the animals around them. While Bayar does not show fear by sitting between two goats and patting them on the back, nor when he was surrounded by the herd of cows. But Mari, on the other hand, seems terrified of the caged gorilla and started crying when her mother took her to see the gorilla while she was at the zoo. Family closeness and gatherings were also one of the differences between cultures.
