Assertion: Jave Apeman, Peking man and Heidelberg man are the fossils of Homo erectus.
Reason: Homo erectus evolved from Homo habilis.
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- Correct answerBIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Solution
The fossil of Java Apeman was discovered from pleistocene rocks in central Java. The fossil of Peking man was discovered from the lime stone caves of Choukoutien near Peking while that of Heidelberg man was discovered in mid pleistocene. All these three fossils come under the category of Homo erectus.
Homo erectus appeared about 1.7 million years ago in middle pleistocene. $H$. erectus evolved from Homo habilis. He was about 1.5-1.8 metres tall. He had erect posture. His skull was flatter than that of modern man. He had protruding jaws, projecting brow ridges, small canines and large molar teeth. He made more elaborate tools of stones and bones, hunted big game and perhaps knew use of fire.
Hence, the correct answer is option: 'B'.
