Which is the correct order in the classification of humans?
Think it through first, then pick an option.
- a Mammalia → Homo → Chordata
- b Homo → Primate → Hominidae
- c Mammalia → Primate → Hominidae
- d Primate → Chordata → Mammalia
Answer and explanation
Correct answer: c Mammalia → Primate → Hominidae
Class Mammalia, Order Primate, Family Hominidae: this is the correct order.
Why the other options are wrong
- a Mammalia → Homo → Chordata: Wrong order: Chordata (phylum) is above Mammalia, and Homo (genus) comes last.
- b Homo → Primate → Hominidae: Wrong order: Primate (order) comes first, then Hominidae (family), then Homo (genus).
- d Primate → Chordata → Mammalia: Chordata is the phylum, above both Mammalia (class) and Primate (order).
