The archaeological evidence of the earliest human foraging on Madagascar may date up to 10,000 years ago. Human settlement of Madagascar occurred by Austronesian peoples, arriving on outrigger canoes from present-day Indonesia.  These were joined around the 9th century AD by Bantu migrants crossing the Mozambique Channel from East Africa.  Other groups continued to settle on Madagascar over time, each one making lasting contributions to Malagasy cultural life. The Malagasy ethnic group is often divided into 18 or more subgroups, of which the largest are the Merina of the central highlands.
