Below are three images of fossil hominin skulls - VCE - SSCE Biology - Question 37 - 2015 - Paper 1

To determine the evolutionary sequence of the skulls:

1. Identify Features: Examine the key features of each skull—such as brow ridge prominence, skull shape, and jaw size.

2. Skull Analysis:

   • Skull 1 may appear to be the most primitive, with a more protruding jaw and less rounded forehead.
   • Skull 2 can be seen as transitional, showing signs of a more modern structure.
   • Skull 3 likely represents the most modern characteristics, with a rounded skull and smaller brow ridge.

3. Evaluate Sequences: Based on the analysis, the sequence from the most ancient to the most modern would be: Skull 1, Skull 2, Skull 3.

4. Choose the Correct Option: From the options provided, the correct answer is therefore:

   • Skull 1, Skull 2, Skull 3
