ISBN 978-0-495-38190-7.H. erectus may have appeared some 2 million years ago. Fossils dated to as much as 1.8 million years ago have been found both in Africa and in Southeast Asia, and the oldest fossils by a narrow margin (1.85 to 1.77 million years ago) were found in the Caucasus, so that it is unclear whether H. erectus emerged in Africa and migrated to Eurasia, or if, conversely, it evolved in Eurasia and migrated back to Africa.

- Now also included in H. erectus are Peking Man (formerly Sinanthropus pekinensis) and Java Man (formerly Pithecanthropus erectus). H. erectus is now grouped into various subspecies, including Homo erectus erectus, Homo erectus yuanmouensis, Homo erectus lantianensis, Homo erectus nankinensis, Homo erectus pekinensis, Homo erectus palaeojavanicus, Homo erectus soloensis, Homo erectus tautavelensis, Homo erectus georgicus. The distinction from descendant species such as Homo ergaster, Homo floresiensis, Homo antecessor, Homo heidelbergensis and indeed Homo sapiens is not entirely clear.

- The type fossil is Mauer 1, dated to ca. 0.6 million years ago. The transition from H. heidelbergensis to H. neanderthalensis at about 0.35 to 0.25 million years ago is largely conventional. Relevant examples are fossils found at Bilzingsleben (also classified as Homo erectus bilzingslebensis).

The first humans with "proto-Neanderthal traits" lived in Eurasia as early as 0.6 to 0.35 million years ago (classified as H. heidelbergensis, also called a chronospecies because it represents a chronological grouping rather than being based on clear morphological distinctions from either H. erectus or H. neanderthalensis), with the first "true Neanderthals" appearing between 0.25 and 0.2 million years ago.
