primate
Definition
Primates are a group of mammals that share a number of characteristics, including:
- Large brains
- Forward-facing eyes
- Opposable thumbs
- Nails instead of claws
- Grasping feet
- Hairy bodies
- Social behaviour
- Intelligence
Primates are found all over the world, in tropical and temperate forests, as well as in some parts of the desert. They are the most intelligent group of mammals, and they are capable of complex social behaviour and tool use.
The earliest primates evolved about 65 million years ago. They were small, tree-dwelling animals that resembled squirrels. Over time, primates evolved larger brains, forward-facing eyes, and opposable thumbs. These adaptations helped primates to become more successful in their environment.
Today, there are about 500 species of primates. They are divided into two main groups: prosimians and anthropoids. Prosimians are the most primitive primates, and they include lemurs, lorises, and bush babies. Anthropoids are more advanced primates, and they include monkeys, apes, and humans.
Primates play an important role in the environment. They help to disperse seeds and pollinate plants. They are also a food source for other animals. Primates are also important to humans. They are used in research, and they are also popular pets.

Different forms of the word
Noun: a member of the order Primates, which includes humans, apes, monkeys, and lemurs.
Adjective: relating to or characteristic of primates.
Etymology
The word "primate" comes from the Latin word "primÄtus", which means "first".
The first recorded use of the word "primate" in English was in the 16th century.

AQA Science Exam Question and Answer
Question:
Define a primate and explain its significance in the study of human evolution. Provide examples of primate characteristics and discuss how they offer insights into the shared ancestry between humans and other primates.
Answer:
A primate is a type of mammal belonging to the order Primates, which includes humans, monkeys, apes, and lemurs. Primates hold great significance in the study of human evolution as they provide insights into our shared ancestry and the evolutionary processes that led to the development of modern humans.
Primates share several key characteristics that highlight their evolutionary connections. These include forward-facing eyes, allowing depth perception, grasping hands and feet with opposable thumbs and big toes, and well-developed brains relative to body size.
Studying primates informs our understanding of human evolution by identifying common traits and adaptations that emerged in ancestral species. Observing behaviours, social structures, and communication patterns among modern primates provides clues about the behaviours and interactions of early human ancestors.
For instance, the study of chimpanzees and bonobos, our closest living relatives, offers insights into social cooperation, tool use, and communication patterns that might resemble the behaviours of early humans. By comparing the anatomical and behavioural traits of primates, researchers gain valuable information about the selective pressures and adaptations that have shaped the evolutionary path leading to Homo sapiens.
