Which hominin was discovered by Eugene Dubois in Java, Indonesia in 1891?

Eugene Dubois discovered Java Man in 1891 in Java, Indonesia. Java Man is a significant find as it is classified as a member of the hominin genus Homo erectus. This discovery was pivotal because it provided evidence for early human ancestors existing outside of Europe and Africa, helping to expand the understanding of human evolution. Dubois' work contributed to the establishment of the idea that humans originated in Asia as well as Africa. The fossil evidence, including a skullcap and a thighbone, suggested that Java Man had both ape-like and human-like characteristics, which made it a critical piece in understanding the connection between modern humans and earlier hominins.

Peking Man is associated with discoveries made in China, Neanderthals are primarily linked to Europe and Asia, and Australopithecus is an earlier genus of hominins that predates Homo erectus. Each of these options represents a different aspect of human evolutionary history, but only Java Man corresponds directly with Dubois' discovery in Java in 1891.
