d. a long, low, wide base; thick bones; and large browridges.

Answer 1

Homo erectus' skull morphology is characterized by a long, low, wide base, thick bones, and large browridges. These features are well-known through fossil records and distinctively describe this species' skull characteristics.

Step-by-step explanation:

The skull morphology of Homo erectus includes distinctive features that have been well-documented through fossil records. These features include:

• A long, low, wide base of the skull.
• Thick bones that make up the cranium.
• Large brow ridges which are prominent.

Additional characteristics of Homo erectus are a projecting nasal spine, a sagittal keel (a raised ridge on top of the head), and a brain size ranging between 1,000 and 1,200 cubic centimeters. This species also possessed a prominent brow and a downward-pointing nose. Given these characteristics, the correct answer to the student's question would be option d. a long, low, wide base; thick bones; and large browridges.
