Which one of the following features is closely related with the evolution of humans?
| 1. | Loss of tail |
| 2. | Shortening of jaws |
| 3. | Binocular vision |
| 4. | Flat nails |
In recent years, DNA sequences (nucleotide sequence) of mtDNA and Y-chromosomes were considered for the study of human evolution, because
| 1. | they can be studied from the samples of fossil remains |
| 2. | they are small and, therefore, easy to study |
| 3. | they are uniparental in origin and do not take part in recombination |
| 4. | their structure is known in greater detail |
Which one is irrelevant to evolution of man?
1. Perfection of hand for tool making
2. Change of diet from hard nuts/roots to soft food
3. Increased ability to communicate or develop community behaviour
4. Loss of tail
Which of the following statement is wrong?
| 1. | The first mammals were shrews |
| 2. | The fauna of North America overrode the mammals of South America. |
| 3. | Continental drift caused Australian mammals to survive because of lack of competition. |
| 4. | The fossils of first mammals are small sized. |
The most recent and direct pre-historic ancestor is:
1. Cro-magnon
2. Neanderthal
3. Pre-neaderthal
4. None of these
A Hominid fossil discovered in Java in 1891, now extinct, having a cranial capacity of about 900 cc was:
| 1. | Homo erectus | 2. | Neanderthal man |
| 3. | Homo sapiens | 4. | Australopithecus |
| I. | Homo habilis | Brain capacity 650-800 cc; probably did not eat meat |
| II. | Homo erectus | Brain capacity about 900 cc; probably ate meat |
| III. | Neanderthal man | Brain capacity 1400 cc; buried their dead |
| 1. | Only I and II |
| 2. | Only I and III |
| 3. | Only II and III |
| 4. | I, II, and III |
| (a) | Homo erectus fossil was discovered in Java in 1981. |
| (b) | The Neanderthal man lived in near east and central Africa between 75,000–10,000 years ago. |
| (c) | Australopithecines were probably taller than 4 feet but did not walk upright. |
| (d) | Few fossils of man-like bones have been discovered in Ethiopia and Tanzania. |
| Column-I | Column-II | ||
| a. | Australopithecines | (i) | Probably ate meat |
| b. | Homo erectus | (ii) | Walked like gorillas |
| c. | Neanderthal man | (iii) | Hunted with stone weapons but essentially ate fruits |
| d. | Ramapithecus | (iv) | (iv) Lived in near east and central Asia |
| Statement A: | Similarities in proteins and genes among diverse organisms indicates common ancestry. |
| Statement B: | Humans and chimpanzees also show biochemical similarities. |
