The response that best reflects what the skulls in the fossil record tell us about hominin evolution is:
The nose became more prominent as hominins evolved.
Throughout hominin evolution, various changes in skull morphology, including the shape and prominence of features like the face and nose, have been observed. While there are changes in jaw size and overall body size, the prominence of the nose and other facial characteristics is more closely associated with adaptations to environmental factors, such as climate and diet.
