Final answer:
To give a skull a life-like appearance, additional features such as skin texture, hair, and facial expressions can be added to the reconstruction using techniques like painting and shading.
Step-by-step explanation:
To give a skull a life-like appearance, additional features can be added to the reconstruction. These features can include adding details such as skin texture, hair, eyebrows, eyelashes, and even facial expressions. Sculptors and forensic artists often use techniques like painting, coloring, and shading to further enhance the realism of the reconstructed skull.
For example, in ancient Jericho, artisans used plaster to cover human skulls and placed shells in the eye sockets, possibly to celebrate ancestors. In modern times, CT scanning, 3D printing, and facial reconstruction techniques have been used to reveal the appearance of individuals based on their skulls.
By adding these additional features, a reconstructed skull can closely resemble a real person, giving it a life-like appearance.
