Final answer:
Homo erectus is believed to have existed on Java from 1.3 to 1.6 million years ago and may have survived until as recently as 50,000 years ago.
Step-by-step explanation:
Fossils of Homo erectus show that this species existed on Java for a significant period in prehistory. This species is believed to have settled on Java between 1.3 and 1.6 million years ago, and they likely traveled there by a land route during the Pleistocene Ice Age when the sea levels were lower. Homo erectus had many features similar to modern humans and may have survived in eastern Asia until about 300,000 years ago, with some evidence suggesting they could have persisted until roughly 50,000 years ago.
