SEGMENT 1: All Things Flow. This segment takes its name from a film it presents that shows the constant motion in nature, through time-lapse photography. Lester R. Aronson, of the museum's Department of Animal Behavior, discusses the cat experiments in progress at that time. SEGMENT 2: Japanese Monkeys. Aronson narrates a film on the social life of an isolated group of Japanese monkeys. The film was made by the Japanese Anthropological Society and won an award at the Venice Film Festival. SEGMENT 3: Genetics. The final segment is the initial broadcast of a projected series on genetics and traces the birth cycle backwards from the moment of birth to the initial fertilization. The program analyzes the almost infinite number of combinations of heredity factors. The John Butler dancers pantomime the story of the formation of the human embryo, including the pairing of the 48 chromosomes. A film of a newborn baby is presented. Harry L. Shapiro, chairman of the AMNH Department of Anthropology, appears in this segment.
