Options

A.
B.
C.
D.

Answer

To identify the skull that has evolved recently among the four given skulls, we can follow these steps:

### Step 1: Analyze the Cranial Capacity
- **Observation**: Compare the size of the skulls. The cranial capacity refers to the volume of the skull which houses the brain.
- **Conclusion**: Generally, as evolution progresses, cranial capacity increases. The skull with the largest cranial capacity is likely to be the most recently evolved.

### Step 2: Examine the Jaw Structure
- **Observation**: Look at the jaw sizes of the skulls. Earlier ancestors had larger, protruding jaws, while more recent species have smaller, less protruding jaws.
- **Conclusion**: A skull with a reduced jaw size indicates a more recent evolutionary stage.

### Step 3: Compare the Skulls
- **Observation**:
- Skull 1 has the smallest cranial capacity and a large protruding jaw, suggesting it is the most primitive.
- Skull 2 has a larger cranial capacity than Skull 1 but still has a relatively protruding jaw.
- Skull 3 has a larger cranial capacity than Skull 2 and shows a slightly protruding jaw, indicative of Neanderthals.
- Skull 4 has the largest cranial capacity and a reduced jaw size, characteristic of modern humans (Homo sapiens sapiens).
- **Conclusion**: Skull 4 is the most advanced in terms of cranial capacity and jaw structure.

### Step 4: Identify the Most Recently Evolved Skull
- **Final Conclusion**: Based on the analysis, Skull 4 is identified as the most recently evolved skull, belonging to Homo sapiens sapiens.

### Summary
- The skulls were analyzed based on cranial capacity and jaw structure.
- Skull 4, with the largest cranial capacity and reduced jaw size, is the most recently evolved.
