Final answer:
Large primates, such as apes and humans, lack a tail and possess characteristics such as large body size, increased brain size, and an opposable thumb. These adaptations help them thrive in their environments.
Step-by-step explanation:
Large living primates that lack a tail, such as apes and humans, have several distinct characteristics that differentiate them from other primates. Some of these characteristics include:
- Lack of tail: Unlike other primates, apes and humans do not have a tail.
- Large body size: Apes and humans are generally larger in size compared to other primates.
- Increased brain size: Apes and humans have a larger brain size in relation to their body size.
- Opposable thumb: Both apes and humans have an opposable thumb, which allows for more precise gripping and manipulation of objects.
These characteristics are adaptations that enable apes and humans to excel in their complex social, cultural, and physical environments.
