Given an example of missing link

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Concept of Missing Link:**
- A missing link refers to a species that exhibits traits common to both an ancestral group and its descendants. It acts as a bridge in the evolutionary chain, showing how two different types of organisms are related.

2. **Example of a Missing Link - Archaeopteryx:**
- One of the most well-known examples of a missing link is Archaeopteryx. This organism lived approximately 150 million years ago and is considered a transitional fossil between reptiles (specifically dinosaurs) and birds.
- Archaeopteryx possessed features of both groups: it had feathers and wings like birds, but also had teeth and a long bony tail like reptiles.

3. **Example of a Missing Link - Australopithecus:**
- Another significant example is Australopithecus, which is often regarded as a missing link between early primates and modern humans.
- Australopithecus exhibited both ape-like and human-like characteristics, such as bipedalism (walking on two legs) and a smaller brain size compared to modern humans.

4. **Conclusion:**
- In summary, Archaeopteryx serves as a missing link between birds and reptiles, while Australopithecus serves as a missing link between early primates and humans. These examples illustrate how certain organisms can provide insight into the evolutionary process.
