The extinct ancient human Homo erectus is a species of firsts. It was the first of our relatives to have human-like body proportions, with shorter arms and longer legs relative to its torso.
<h3>What are Homo erectus?</h3>
Homo erectus, an extinct species of Pleistocene archaic human, first appeared about 2 million years ago. Several human species, including H. heidelbergensis and H. antecessor, seem to have diverged from H. erectus, with the former being largely accepted as the ancestor of Neanderthals, Denisovans, and modern humans. Among the first recognizable representatives of the genus Homo are its specimens. The first known ancestor of modern humans, H. erectus, had a continental range that stretched from the Iberian Peninsula to Java. H. floresiensis and possibly H. luzonensis may have its origins in Asian populations of Homo erectus. H. erectus soloensis, from Java, dates to a time period between 117,000 and 108,000 years ago.
