Pouched mammals of Australia survived because:
| 1. | they all are top predators in a food chain |
| 2. | they are all herbivores and hence get to feed on large amounts of available primary production |
| 3. | of lack of competition from any other mammals |
| 4. | the Australian environment is not conducive for the survival of true placental mammals |

What does it mean to say that evolution is a stochastic process?
| 1. | Evolution is a predictable and deterministic process. |
| 2. | Evolution is solely driven by natural selection. |
| 3. | Evolutionary changes are due largely to random genetic mutations and chance events. |
| 4. | Evolution only occurs in predictable environments. |
