In which of the, the cranial cavity was smallest ?

Options

A. Cro-Magnon
B. Neanderthal
C. Peking man
D. Java ape-man

Answer

To determine which of the following had the smallest cranial cavity among Cro-Magnon man, Neanderthal, Packing man, and the Java ape man, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Cranial Cavity**:
- The cranial cavity is the space within the skull that houses the brain. The size of this cavity can give insights into the brain volume and potential intelligence of the species.

2. **Identify the Species**:
- The species mentioned are:
- Cro-Magnon man
- Neanderthal
- Packing man
- Java ape man (also known as Homo erectus erectus)

3. **Evolutionary Context**:
- Recognize the evolutionary timeline:
- Homo habilis → Java ape man (Homo erectus erectus) → Packing man → Neanderthal → Cro-Magnon man.
- As we move through this evolutionary sequence, there is a general trend of increasing cranial capacity.

4. **Compare Cranial Capacities**:
- Java ape man (Homo erectus erectus) is known to have the smallest cranial cavity among the listed species.
- Cro-Magnon man has the largest cranial cavity, followed by Neanderthals and then Packing man.

5. **Conclusion**:
- Based on the evolutionary progression and cranial cavity sizes, the Java ape man is identified as having the smallest cranial cavity.

### Final Answer:
The Java ape man had the smallest cranial cavity among the options provided.
