Question 2

Answer 2

Split into two suborders - Strepsirrhini and Haplorrhini.

Strepsirrhini is split into one infraorder - Lemuriformes, which is split into the two superfamilies Lemurs and Lorises.

Haplorrhini is split into two infraorders - Tarsiiformes (1 family, Tarsiers) and Simiiformes.

Simiiformes are split into two parvorders - Platyrrhini (New World monkeys) and Catarrhini.

Catarrhini is split into two families - Cercopithecoidea (Old World monkeys) and Hominoidea (apes, including humans).
