Question

Predation is a significant pressure on primates. How may a primate respond if predation pressure is high and body size is small? Live in large groups to reduce individual risks. Live in small groups to be better able to hide predators. Live in intermediate from groups. Answers a. and b., because both strategies can lead to reduced predation pressure. Primates are widespread across the globe but are not found in: Mexico. Australia. Japan. Philippines. Why are Plesiadapiforms considered primate-like mammals but not primates? Because they were quadrupedal. Because they had a very well developed sense of smell Because they lacked a postorbital bar. Because their eyes were oriented laterally in the skull. At about 23-25 mya apes diverged from monkeys. Which is an unfailing ape trait: A 2.1.2.3 tooth formula. Y-5 lower molar pattern. Bilophodont molars. Quadrupedal locomotion. Oligocene primates including, the Aegyptopithecus zeuxis family, are important: Because it is possible that all modern old world monkeys and apes are derived from this family. Because all members of this family were quadrupedal and lived in trees, which is the typical form of locomotion of old world primates. morphism in the family exceeded dimorphism observed in other sexual oligocene primate families and sexual dimorphism becomes an important anthropoid trait Because most species of this primate family were primarily frugivorous and fruit later becomes an important item in the diet of monkeys.

Explanation / Answer

Solution 36: The correct option is Option A

When it comes to group living, most mammals are solitary. The disadvantages of group living include the most obvious reasons of competition for resources. Living in big groups can also increase the costs of movement, and increased risk of transmission of diseases and parasites.

In spite of this, primates like monkeys and apes live in groups. There are two main hypothesized benefits:
1 benefits associated with the acquisition of food
2 benefits associated with reducing predation risk

Additionally, primates rely upon alarm calls to warn the other members of the presence of a predator They also resort to mobbing when living in larger groups. For example, baboons will mob any small carnivore, even cheetahs and jackals. When an animal lives in large groups, it can mob large predators which it couldn't do if it was alone. Chimps have been seen to mob leopards and lions. Rhesus monkeys have been seen to mob tigers.

Studies on primates have shown group sizes to be larger when predation pressure was higher.
