What are the two superfamilies of strepsirrhines?

The correct answer identifies the two superfamilies of strepsirrhines as Lemuroidea and Lorisoidea. Strepsirrhines are a suborder of primates that include lemurs, lorises, and galagos, and they are characterized by certain anatomical features such as a more developed sense of smell and the presence of a wet nose.

Lemuroidea refers specifically to the group that encompasses all lemurs, which are primarily found in Madagascar. Conversely, Lorisoidea includes lorises and galagos, which inhabit parts of Africa andAsia. Understanding these two superfamilies is essential for studying the taxonomy and evolutionary relationships among primates, especially since they exhibit distinct adaptations to their environments.

The other choices encompass broader or different classifications that do not accurately reflect the superfamilies within strepsirrhines. For example, Haplorrhini and Strepsirrhini refer to two different suborders of primates, rather than superfamilies. Similarly, the terms Prosimians and Anthropoids encompass larger groups that go beyond the strepsirrhines themselves, while Tarsiiformes and Platyrrhini refer to different evolutionary branches altogether within the primate taxonomy.
