Which animal has a large brain in proportion to its body?
Think it through first, then pick an option.
- a tiger
- b lion
- c human
- d elephant
Answer and explanation
Correct answer: c human
Humans are in genus Homo because their brain is the largest for their body size.
Why the other options are wrong
- a tiger: Not the tiger; the largest brain for body size is the trait of genus Homo (humans).
- b lion: Not the lion; the book gives this as the reason for the human genus Homo.
- d elephant: An elephant's brain is large, but the largest brain for body size is the human's (Homo).
