Question

Among the anatomical contrasts that distinguish H. erectus from modern humans are

a) Larger cranial capacity
b) Reduced brow ridges
c) Smaller limb proportions
d) Absence of bipedalism

Answer 1

Homo erectus can be distinguished from modern humans by its larger cranial capacity, reduced brow ridges, and smaller limb proportions.

Step-by-step explanation:

The anatomical contrasts that distinguish Homo erectus from modern humans are:

1. Larger cranial capacity: H. erectus had a progressive increase in brain size from about 550 cc to 1,250 cc, showing a larger capacity than modern humans.
2. Reduced brow ridges: While H. erectus had a prominent brow ridge, modern humans have reduced brow ridges.
3. Smaller limb proportions: H. erectus is taller than any other previous hominin, with longer legs that provided the ability to run great distances and chase prey.
