A long-lived human species with near-modern body proportions, the first known to spread widely beyond Africa, about 1.9 million–110,000 years ago.
See it on the Life map →What happened
Homo erectus had long legs, shorter arms and a body size close to ours, suited to walking and running long distances in open country. Its brain grew from about 600 to over 1,100 cc over its history. It made Acheulean handaxes from about 1.76 million years ago and spread to Georgia, China and Java. The first fossil, 'Java Man', was found by Eugène Dubois in 1891; the near-complete 'Turkana Boy' skeleton was found in Kenya in 1984.
Why it matters
Erectus was the first hominin with a humanlike body and the first known to range across Asia. It lasted about 1.8 million years, several times longer than our species so far.
The evidence (fossils, genes, rocks)
Hundreds of fossils from Africa, Georgia, China ('Peking Man') and Java, dated by volcanic ash, magnetic reversals and other methods; the youngest, from Ngandong, Java, are about 117,000–108,000 years old.
Still debated
Whether early African fossils form a separate species (Homo ergaster), and how erectus relates to later species such as heidelbergensis and floresiensis.

Connections (5)
▸Homo habilis may have led to Homo erectusDebated
The connection
Homo habilis appears earlier than Homo erectus, and its brain and teeth are intermediate, so it was long seen as erectus's ancestor. But habilis fossils as young as about 1.44 million years show it lived alongside erectus, so habilis may be a sister branch rather than a direct parent.
When and how
East Africa, about 2.4–1.4 million years ago; key finds published in 2007 from Ileret, near Lake Turkana, Kenya, by Fred Spoor and Meave Leakey.
How sure are we?
Fossil dating shows habilis came first, but overlapping dates and a thin record leave the ancestor question open.
Debates and open questions
Whether erectus came from habilis, from Homo rudolfensis or from an unknown population, and whether these are truly separate species. Dmanisi's varied skulls add to the puzzle.
▸Dmanisi skulls (Georgia) preserve early Homo erectusWell established
The connection
The Dmanisi fossils show Homo erectus at an early stage: small brains (about 550–780 cc), short stature and simple tools. They reveal that early erectus left Africa before big brains and handaxes evolved, and that skulls varied widely within one population.
When and how
Dmanisi, Georgia, in the Caucasus; fossils found from 1991 beneath a medieval town by David Lordkipanidze's team, dated about 1.85–1.77 million years ago.
The evidence
Five skulls, plus jaws and limb bones, from one site, dated by volcanic rock and magnetic reversals, and compared closely with African erectus fossils.
Debates and open questions
Some call the fossils a separate species, Homo georgicus. The 2013 claim that their variation means several African 'species' were really one lineage remains contested.
▸Homo erectus probably mastered Control of fireDebated
The connection
The earliest convincing traces of fire, burned bone and plant ash about 1 million years ago in South Africa's Wonderwerk Cave, lie with handaxes of the kind erectus made. Fire for warmth, protection and cooking may have helped erectus settle colder and more varied lands.
When and how
Wonderwerk Cave, South Africa, about 1 million years ago; possible older traces in Kenya about 1.5 million years ago; Gesher Benot Ya'aqov, Israel, about 780,000 years ago.
How sure are we?
Microscopic analysis of burned material deep inside the cave argues against wildfire there. Older open-air sites could reflect natural fires, so the timing is debated.
Debates and open questions
Whether erectus made fire or only captured it from wildfires, and whether cooking began early enough to drive its larger brain, as primatologist Richard Wrangham argues.
▸Homo erectus probably led to Homo heidelbergensisStrong evidence
The connection
By about 700,000 years ago, larger-brained humans appear in Africa and Europe, with brains of about 1,100–1,300 cc versus erectus's 600–1,100. Most researchers think an African erectus population evolved into this group, which kept making handaxes but with more refinement.
When and how
Africa and Europe, about 800,000–600,000 years ago; fossils such as the Bodo skull (Ethiopia) and the Mauer jaw (Germany), both about 600,000 years old.
How sure are we?
Skull shapes intermediate between erectus and later humans, in a matching time sequence. Spain's Homo antecessor fossils, about 850,000 years old, complicate the picture.
Debates and open questions
Whether Homo antecessor or other populations sit between them, and whether heidelbergensis is a real species or a convenient label for varied fossils.
▸Homo floresiensis ('the hobbit') may descend from Homo erectusDebated
The connection
Homo erectus reached nearby Java by roughly 1.5 million years ago. One idea is that some erectus crossed to Flores and shrank over hundreds of thousands of years, as island mammals often do when food is limited. Tiny 700,000-year-old jaw, teeth and arm-bone fossils from Mata Menge support this.
When and how
Flores, Indonesia; Mata Menge fossils about 700,000 years old, published in 2016 and 2024; stone tools on Flores about 1 million years old.
How sure are we?
Mata Menge teeth and a tiny arm bone resemble Javan erectus in shape. Small size alone does not prove descent.
Debates and open questions
Its wrists, feet and very small brain look more primitive than erectus, so some argue it descends from an earlier, habilis-like hominin that left Africa.
