Question

Java Man is
A. Pithecanthropus erectus
B. Pithecanthropus pekinensis
C. Komo rhodesinensis
D. Homo heidelbergensis

Answer 1

Hint: Evolution is the change of characteristics and adaptation of species over millions of years. Human evolution showed the changes in the human species right from walking on four legs to complete erect posture and many more characteristics.

Complete answer:
Java man is a part of the tree of human evolution. Java man is a human fossil that was discovered in the year 1891-92. It was found on the Java land part of Indonesia. So, it is known as Java man. The excavation team was led by Eugene Debois and he named the fossil of java man as Pithecanthropus erectus.

Pithecanthropus pekinensis is known as Peking man. It was discovered around 1929-37 in Beijing China.
Komo rhodesinensis: There is no such human fossil in the history of human evolution.
Homo heidelbergensis: It is a human fossil found in the Pleistocene era in Heidelberg Germany. So, it is named Homo heidelbergensis.

Evolution of humans: It has been traced that human evolution appeared to have evolved from a tree-dwelling shrew-like animal. This process began in the Palaeocene epoch. Major changes that took place in the evolution of man include an increase in size and complexity of the brain and enhanced intelligence, increase in cranial capacity, bipedal locomotion, opposable thumb, erect posture, shortening of forelimbs and lengthening of hind limbs, development of chin, broadening of the pelvic girdle, development of lumbar curvature, social and cultural development (articulated speech, art, development of tools, etc).
Human evolution: Dryopithecus: Dryopithecus was more ape like. It was found nearly 20 – 25 mya ago.

Ramapithecus: Ramapithecus was more man-like. It was found nearly 14-12 mya ago.
Australopithecus: Australopithecus evolved around 4 million years ago. Not taller than 4 feet, jaws larger, prognathous face, chin absent, lumbar curvature present. He was a man with an ape brain.
Cranial capacity: 450 to 600 cc

Homo habilis: Handyman. It was found nearly 2.5 to 1.4 mya. The lower jaw, lightly built, dentition more like modern man, smaller molars. did not eat meat, made tools from stones, nicknamed handy man.
Cranial capacity: 650 to 800 cc.
Homo erectus: Ape man. It was found nearly 1.5 mya ago. 5 feet in height prognathus face, massive jaws, Huge teeth, chin absent, Bony eyebrow ridges present. They ate meat, omnivorous might have used fire.
Cranial capacity: 900 cc

Neanderthal man: Advanced prehistoric man. It was found nearly 100000 to 40000 yrs ago. Heavy built short prominent brow ridges, low forehead, deep jaws, chin absent, outwardly curved thigh bones. They used hide (animal skin), buried their dead, constructed flint tools
Cranial capacity: 1400cc

Homo- sapiens: Modern man. developed distinct races. Developed cave art about 18000 yrs ago
Cranial capacity: 1450cc.

Hence, the correct answer is option (A)

Note: Homo is the genus under which different human species like habilis, erectus, sapiens, etc are there. Pithecanthropus erectus, Pithecanthropus pekinensis come under Homo erectus.
