 In 200 BCE, a loosely connected group of Lapita colonists from Island Melanesia also migrated back northwards, settling the islands of eastern Micronesia almost simultaneously.This region became the center of another wave of migrations radiating outwards, reconnecting them with other settled islands in western Micronesia.Around 800 CE, a second wave of migrants from Southeast Asia arrived in the Marianas, beginning what is now known as the Latte period.
