Less hair makes cold easier to feel. Why didn’t that wipe humans out?
Show answer & explanation
Answer: Behavior helped compensate
Behavior helped compensate ✓ — Correct! Early humans could offset some of the cost through behavior and tools, using shade, fire, shelter, grouping, and better timing of activity.
Humans stopped feeling cold — Wrong. Humans still feel cold. The key is that behavior can reduce the cost of being less furry.
Skin made extra heat — Wrong. Skin helps regulate heat, but it is not a special new heat-making engine that replaced body hair.
