Which of the following had the smallest brain capacity?

Options

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

Explanation

To determine which of the following had the smallest brain capacity, we can analyze the brain sizes of various hominins. Here’s a step-by-step breakdown:

### Step 1: Identify the Hominins
We need to consider the following hominins:
1. Homo Erectus
2. Homo Sapiens
3. Homo Neanderthalensis
4. Homo Habilis

### Step 2: Gather Brain Size Information
Next, we will look at the brain sizes associated with each of these hominins:
- **Homo Erectus**: Approximately 900 cc
- **Homo Sapiens**: Approximately 1450 cc
- **Homo Neanderthalensis**: Approximately 1400 cc
- **Homo Habilis**: Approximately 650 to 800 cc

### Step 3: Compare Brain Sizes
Now, we will compare the brain sizes:
- Homo Habilis: 650 to 800 cc (smallest)
- Homo Erectus: 900 cc
- Homo Neanderthalensis: 1400 cc
- Homo Sapiens: 1450 cc (largest)

### Step 4: Identify the Smallest Brain Capacity
From the comparison, it is clear that **Homo Habilis** has the smallest brain capacity, ranging from 650 to 800 cc.

### Conclusion
Thus, the answer to the question "Which of the following had the smallest brain capacity?" is **Homo Habilis**.
