How far back does H. erectus date?

Homo erectus is understood to have existed from approximately 1.8 million to around 200,000 years ago, making this time frame significant in the study of human evolution. This species is notable for its role in marking the transition to more advanced behaviors, including the use of tools and control of fire, and its physical characteristics reflect adaptations for both climbing and walking long distances.

The dating of H. erectus is supported by various fossil finds in Africa and parts of Asia, illustrating its widespread presence during the Pleistocene epoch. This span indicates a prolonged existence that contributed to the evolutionary lineage leading to modern humans, emphasizing the species' importance in our understanding of hominin development.

The other timelines do not accurately represent the known fossil record or the estimated existence of H. erectus, making them less relevant in identifying the proper historical context for this species.
