To determine which statement is incorrect, let's analyze each option step by step:

1. **Statement 1: Homo erectus lived on earth around 1.5 to 1.7 million years ago.**
- Homo erectus is indeed known to have existed approximately 1.9 million years ago to about 110,000 years ago. Therefore, this statement is correct.

2. **Statement 2: Homo sapiens appeared in African grassland.**
- Homo sapiens are believed to have originated in Africa, and the grasslands were one of the habitats they inhabited. Thus, this statement is also correct.

3. **Statement 3: Archaeopteryx had characters of birds and reptiles.**
- Archaeopteryx is known as a transitional fossil that exhibits features of both birds (such as feathers) and reptiles (such as teeth and a long tail). Therefore, this statement is correct.

4. **Statement 4: All the Darwin finches were discovered on a single island of Galapagos.**
- This statement is incorrect. The Darwin finches are a group of species that were discovered across multiple islands in the Galapagos archipelago, not just one island.

**Conclusion:**
