The activity of an organism depends on the total activity of its cells, with energy flow occurring within and between them. Cells contain hereditary information that is carried forward as a genetic code during cell division. [145] There are two primary types of cells, reflecting their evolutionary origins.

Males establish social bonds, dominance, or general group consensus. [34] They can make dog-like barks [29] when threatened or when females are herding young. [35]
