Final answer:
True, primates are omnivores and their diet includes insects, birds, eggs, and small mammals alongside plant material.
Step-by-step explanation:
The statement that non-human primate meat sources include insects, birds, eggs, and small mammals is true. Primates are mostly omnivorous, which means that they consume both plant and animal material. Their diverse diet can include items such as fruits, leaves, insects, and small vertebrates. This lifestyle is evident across various primate species, from lemurs and tarsiers to monkeys and apes. Humans, part of the primate family, also historically consumed a variety of foods, although modern diets have evolved to include more processed and agriculturally sourced foods.
