The chronological order of human evolution from early to the recent is:
| 1. | Ramapithecus → Australopithecus → Homo habilis → Homo erectus |
| 2. | Ramapithecus → Homo habilis → australopithecus → Homo erectus |
| 3. | Australopithecus → Homo habilis → Ramapithecus → Homo erectus |
| 4. | Australopithecus → Ramapithecus → Homo habilis → Homo erectus |
According to Hugo de Vries, the mechanism of evolution is:
| 1. | Phenotypic variations | 2. | Saltation |
| 3. | Multiple-step mutation | 4. | Minor mutations |
Among the following sets of examples for divergent evolution, select the incorrect option:
| 1. | Brain of bat, man and cheetah |
| 2. | Heart of bat, man and cheetah |
| 3. | Forelimbs of man, bat and cheetah |
| 4. | Eye of octopus, bat and man |
The similarity of bone structure in the forelimbs of many vertebrates is an example of:
1. Convergent evolution
2. Analogy
3. Homology
4. Adaptive radiation
Sickle cell anaemia has not been eliminated from African population as
1. It is controlled by dominant genes
2. It is controlled by recessive genes
3. It is not a fatal disease
4. It provides immunity against malaria
In the famous experiment by Louis Pasteur, the straight and long-necked flasks served :
1. as the experimental setup
2. as a control
3. as a cohort
4. no useful purpose
In the human population the frequency of which of the following will always be more than what is apparent?
| 1. | somatic mutations | 2. | dominant alleles |
| 3. | recessive alleles | 4. | females |
Which of the following statements about fossil evidence for evolution is correct?
| 1. | Fossil evidence shows a sudden and complete appearance of modern species without transitional forms. |
| 2. | Fossils of transitional forms, such as Archaeopteryx, demonstrate the evolutionary link between reptiles and birds. |
| 3. | The fossil record is complete and provides evidence for every stage of evolution in all organisms. |
| 4. | Fossils primarily show that extinct species were entirely unrelated to modern species. |
