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?

Ans. Speciation plays a crucial role in increasing biodiversity by creating new species with unique characteristics. This diversity is important for the overall health and stability of ecosystems.

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.
