Part 4/9:
The discovery of Homo erectus fossilized remains began with Dutch surgeon Eugene Dubois in 1891 in Indonesia, back when anthropological consensus leaned toward an "Out of Asia" hypothesis for human origins. Initially named Pithecanthropus erectus, these remains were later classified as Homo erectus, leading to an ongoing exploration of various subspecies or lineages including H. ergaster, H. georgicus, and H. soloensis, which complicates classification but demonstrates the diversity within the species.
