Answer:
Primates that show ecological adaptations similar to those presented by humans and great primates such as chimpanzees and gorillas that are genetically similar to humans.
Step-by-step explanation:
Primatology is the science that studies the entire order of primates, from their ancestral forms to the most modern forms that you can see today. In addition to studying the behavior and biological and evolutionary conditions of these animals, these scientists seek to associate the information found with the study of some primates to explain elements of human beings. In this case, the most relevant primates are monkeys and terrestrial primates because they have biological adaptations similar to those presented by humans; and, great primates that have a strong genetic similarity to humans, such as chimpanzees and gorillas.
