Explanation

To determine the correct sequence of human evolution, we can outline the major stages and species involved in the evolutionary process of humans. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Identify the Earliest Ancestors**: The first known ancestor in the evolution of humans is **Dryopithecus**. This species is believed to have lived around 12 to 9 million years ago and is considered a common ancestor of both humans and apes.

2. **Next in Line**: Following Dryopithecus, we have **Ramapithecus**, which is often considered a more advanced form of Dryopithecus. It lived around 14 to 8 million years ago and is thought to have traits that are closer to modern humans.

3. **Australopithecus**: The next significant stage is represented by **Australopithecus**, which lived approximately 4 million years ago. This genus is crucial in human evolution as it shows evidence of bipedalism (walking on two legs).

4. **Homo habilis**: After Australopithecus, we see the emergence of **Homo habilis**, which lived around 2.4 to 1.4 million years ago. This species is known for its use of tools and is often referred to as the "handy man."

5. **Homo erectus**: Following Homo habilis, we have **Homo erectus**, which existed from about 1.9 million years ago to as recently as 110,000 years ago. This species is notable for its upright walking and use of fire.

6. **Homo Neanderthalensis**: The next stage is represented by **Homo Neanderthalensis** (Neanderthals), who lived approximately 400,000 to 40,000 years ago. They are known for their robust build and adaptation to cold climates.

7. **Homo sapiens (Cro-Magnon Man)**: Finally, we arrive at **Homo sapiens**, which includes the Cro-Magnon Man. This species represents modern humans and emerged around 40,000 years ago. Cro-Magnons are known for their advanced tools, art, and social structures.

### Conclusion:
The correct sequence of human evolution is:
1. Dryopithecus
2. Ramapithecus
3. Australopithecus
4. Homo habilis
5. Homo erectus
6. Homo Neanderthalensis
7. Homo sapiens (Cro-Magnon Man)
