| A. | It is a process in which individuals with certain heritable traits survive and reproduce at a higher rate than do other individuals |
| B. | It is a process that occurs through interactions between individuals and their enviornment resulting in the evolution of individuals |
| C. | It is a process that can over time, increase the frequency of favourable adaptations in a given enviornment |
| D. | It is a process that disropts the adaptation of individuals to a new environment |
| E. | Natural selection may lead to speciation |
| Statement I : | When the two species are morphologically almost identical but do not normally interbreed, such species are sibling species. |
| Statement II: | A sub population becomes reproductively isolated in the midst of its parent population. This is allopatric speciation. |
| 1. | Both the statement I and statement II are true |
| 2. | Both statement I and statement II are false |
| 3. | Statement I is correct but statement II is false |
| 4. | Statement I is incorrect but statement II is true |
| Statement I: | In England, during the Industrial Revolution, the black-colored form of Biston Betularia became dominant over the light-colored form of moth because of natural selection, the darker forms were selected. |
| Statement II: | Prior to the Industrial Revolution, the peppered moths exhibited protective mimicry and the light-colored moths were not noticed by predatory birds due to light-colored lichens on the bark of trees. |
| Statement I: | Mutations are random and direction less, while Darwinian variations are small and directional. |
| Statement II: | Darwin's finches represent one of the best examples of adaptive radiation. |
| 1. | Both statement I and statement II are correct |
| 2. | Both statement I and statement II are incorrect |
| 3. | Statement I is correct but statement II is incorrect |
| 4. | Statement I is incorrect but statement II is correct |
