Among the human ancestors the brain size was more than 1000 cc in:

Options

A. Homo habilis
B. Homo neanderthalensis
C. Homo erectus
D. Ramapithecus

Answer

To determine which human ancestor had a brain size greater than 1000 cc, we will analyze the cranial capacities of the mentioned species:

1. **Homo habilis**:
- The cranial capacity of Homo habilis is approximately 600 to 700 cc.
- This is below 1000 cc.

2. **Homo neanderthalensis (Neanderthals)**:
- The cranial capacity of Neanderthals ranges from 1000 to 1200 cc.
- This exceeds 1000 cc.

3. **Homo erectus**:
- The cranial capacity of Homo erectus is about 950 cc.
- This is still below 1000 cc.

4. **Homo ramapithecus**:
- Homo ramapithecus does not have a defined cranial capacity as it is considered to have a very primitive brain structure.
- Therefore, it does not exceed 1000 cc.

Based on the analysis above, the only human ancestor among the options that had a brain size greater than 1000 cc is **Homo neanderthalensis (Neanderthals)**.

**Final Answer**: Homo neanderthalensis (Neanderthals)
