Question

The scientific name of Java man is
(a)Homo habilis
(b)Homosapiens neandarthalensis
(c) Homo erectus erectus
(d) Australopithecus boisei

Answer 1

Hint: It is extinct species of the human genus, perhaps an ancestor of modern humans. It most likely originated in Africa, though Eurasia cannot be ruled out.

Complete answer
Homo erectus erectus is the scientific name of Java man. It is known from when fossil remains were found on the island of Java and Indonesia. The skullcap and thighbone were found by the Dutch anatomist and geologist Eugene Dubois in the mid-1890s. Java man was differentiated by its cranial capacity averaging 900 cubic cm, a skull flat in profile with the little forehead, very thick skull bones, heavy forehead ridges, a crest along the top of the head for the attachment of incredible jaw muscles, and a massive jaw with no chin.

Additional information
Regardless of where it first evolved, the species seems to have dispersed quickly, starting about 1.9 million years ago near the middle of the Pleistocene Epoch, moving through the African tropics, Europe, South Asia, and Southeast Asia.
In 1954–1955 in North Africa, unearthings at Tighenif (Ternifine), east of Mascara, Algeria, yielded remains dating to around 700,000 years prior whose closet affinities appeared to be with the Chinese form of H. erectus. Other Moroccan hominin section from this region which parts of a skull is found in 1933 close to Rabat and jaws and teeth from Sidi Abderrahman in Morocco—the show features reminiscent of H. erectus, however, they are preferably further developed in structure over those of Tighenif and Asia. Another fossil compared to H. erectus is a 400,000-year-old cranium found in 1971 at Sale, Morocco.

So, the correct answer is ‘Homo erectus erectus’.

Note: A traditional view held by certain paleontologists is that a species may be changed gradually into a succeeding species. Such progressive species in the evolutionary sequence are called chronospecies. The boundaries between chronospecies are practically difficult to determine utilizing any objective anatomic or functional criteria; along with these, all that is left is the guesswork of drawing a boundary at a moment in time.
