Statement A: | Similarities in proteins and genes among diverse organisms indicates common ancestry. |
Statement B: | Humans and chimpanzees also show biochemical similarities. |
Assertion(A): | Among primates, chimpanzee is closest relative to the present day humans. |
Reason(R): | The banding pattern of autosomes 3 and 6 of humans and chimapanzee is remarkably similar. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion(A): | From evolutionary point of view, human gestation period is believed to be shortening. |
Reason(R): | One major evolutionary trend in humans has been the larger head undergoing relatively faster growth in the foetal stage. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion(A): | Human beings possess the property of language skills and self-consciousness. |
Reason(R): | Chimpanzee are also animals with the property of self-consciousness. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |

3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion (A): | Habitat fragmentation and genetic drift ultimately result in evolution. |
Reason (R): | These phenomena accentuate variations that lead to speciation. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
