The correct order, from earliest to latest, is Homo habilis, Homo ergaster, Homo erectus, and then Homo heidelbergensis. Homo habilis is one of the earliest members of the genus Homo, appearing about 2.1 to 2.8 million years ago. Homo ergaster and Homo erectus are closely related, with Homo ergaster often considered an African variant of Homo erectus, which spread out of Africa. Homo heidelbergensis appeared later, around 600,000 to 200,000 years ago, and is thought to be a common ancestor of both Neanderthals and modern humans.
