Final answer:
Anatomical traits in male primates that experience intense male-male competition include sexual dimorphism, larger body size, and elaborate adornments/colors. These traits have evolved through sexual selection, where males compete for mating opportunities with females.
Step-by-step explanation:
Anatomical traits that we see in male primates that experience intense male-male competition include sexual dimorphism, larger body size, and elaborate adornments or colors. These traits have evolved through sexual selection, where males compete for mating opportunities with females. In many primate species, males are larger and more decorated than females, as they compete with other males for access to females. This is seen in various primates such as gorillas and certain monkeys.
