The most non-derived or primitive primates are lemurs and lorises (option a)
The most non-derived or primitive primates are lemurs and lorises (option a).
Lemurs are found only on the island of Madagascar and are considered the most primitive primates due to their similarities with early primate ancestors. They have features such as a wet nose, elongated snout, a grooming claw on their second toe, and a toothcomb made up of specialized lower incisors and canine teeth. Lemurs have a less specialized brain and exhibit a wide range of behaviors and adaptations.
Lorises, on the other hand, are found in Africa and Asia. They possess some primitive characteristics like a wet nose, elongated snout, and grooming claw on their second toe, which are also seen in lemurs. Lorises are primarily nocturnal and arboreal, spending most of their time in trees. They have a slow metabolic rate, which contributes to their slow movements and ability to stay still for long periods. These traits are considered more primitive compared to other primates.
It is important to note that the term “primitive” here refers to primitive characteristics that resemble those of early primate ancestors. It does not mean that lemurs and lorises are less evolved or less adapted to their environments. They have evolved and adapted to their respective habitats over millions of years, but they retain some ancestral features that distinguish them as more non-derived or primitive primates.
