The Kumulipo is an ancient Hawaiian chant that details the genealogy and creation of Hawaii according to their oral tradition. It divides history into 16 periods and traces the lineage of Papahanaumoku (Earth Mother) and Wākea (Sky Father) whose union created the Hawaiian islands and people. Their firstborn was a premature fetus named Hāloanakalaukapalili which became the first kalo plant, and their second born was the first Hawaiian man, Hāloa. The kalo plant and Hawaiian people are considered siblings and the kalo holds cultural significance as the main sustenance crop and source of the Hawaiian word for family, ʻohana.
