Question

based on the data that you collected from the virtual lab, which primate had the smallest skull or supraorbital height (shi)?

homo sapiens (modern human)
pan troglodytes (modern chimpanzee)
australopithecus afarensis (extinct hominid)
homo erectus (extinct hominid)

Explanation:

Define supraorbital height index

The supraorbital height index (SHI) measures the height of the braincase above the brow ridge.

Compare primate skull features

Using Hominid Evolution concepts, modern chimpanzees (Pan troglodytes) have a very flat, low braincase.

Identify the smallest value

Modern humans have the highest SHI, while chimpanzees have the smallest SHI among the options.

Answer:

• (A) Homo sapiens (Modern human)
• (B) Pan troglodytes (Modern Chimpanzee) (Correct answer)
• (C) Australopithecus afarensis (Extinct hominid)
• (D) Homo erectus (Extinct hominid)
