Darwin's finches are examples of ..........................Speciation.

Explanation

**Step-by-Step Solution:**

1. **Understanding Darwin's Finches**: Darwin's finches are a group of bird species that Charles Darwin studied during his visit to the Galapagos Islands. He observed that these finches had different physical characteristics and behaviors despite sharing a common ancestor.

2. **Identifying the Concept of Speciation**: Speciation is the process through which new species arise. There are different types of speciation, including allopatric, sympatric, parapatric, and peripatric speciation.

3. **Recognizing Adaptive Radiation**: The phenomenon observed in Darwin's finches is known as adaptive radiation. This occurs when a single ancestral species diversifies into multiple species, each adapted to different environments or ecological niches.
