| 2. What are the different types of speciation? | |
Ans. The two main types of speciation are allopatric speciation, which occurs when populations are geographically isolated, and sympatric speciation, which occurs within the same geographic area.
| 3. How does speciation contribute to biodiversity? | |

| 4. What are the factors that can lead to speciation? | |
Ans. Factors that can contribute to speciation include geographic isolation, genetic drift, natural selection, and mutations. These factors can drive populations to diverge and eventually become reproductively isolated from each other.
