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

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about human ancestors with a brain size greater than 1000 cc. This refers to the cranial capacity, which is the volume of the brain measured in cubic centimeters (cc).

2. **Identifying the Options**: The options provided are:
- Homo Erectus
- Ramapithecus
- Homo Habilis
- Homo Neanderthals

3. **Researching Brain Sizes**:
- **Homo Neanderthals**: Their cranial capacity ranges from approximately 1300 to 1600 cc.
- **Homo Erectus**: Their cranial capacity is around 800 to 1000 cc.
- **Homo Habilis**: Their cranial capacity is about 375 cc.
- **Ramapithecus**: This species is much older and had a smaller cranial capacity, but specific values are less commonly cited.

4. **Comparing the Brain Sizes**:
- Homo Neanderthals clearly have a cranial capacity greater than 1000 cc.
- Homo Erectus is on the cusp but does not consistently exceed 1000 cc.
- Homo Habilis and Ramapithecus have significantly smaller cranial capacities.

5. **Conclusion**: Based on the cranial capacities, the only ancestor among the options with a brain size greater than 1000 cc is **Homo Neanderthals**.

**Final Answer**: Homo Neanderthals
