Animals have teeth that have evolved to help them eat their food easily and gain the most nutrition possible. Primates have flat, grinding molars. This allows them to eat vegetation and plants that may be difficult to eat with only sharp teeth. Human beings have the same kind of teeth, which allows us to eat meat and plants. Human's teeth can chew both efficiently; some primates can eat insects because of this.
Human beings were able to evolve and develop tools partially due to having opposable thumbs. All primates have opposable thumbs, which allow them to grip objects, pick things up, and turn knobs. Primates also have a strong grip, which gives them the ability to handle things firmly without dropping them. Primates have what is termed "precision grip," so their hands can make precise, detailed movements. Most animals do not have these abilities.
Primates, like all mammals, give birth to live young. Like humans, primates have evolved to having fewer offspring, usually having only one child at a time. This is because primates devote years of their lives to raising their children. Primates have an elaborate social structure and every member of the group knows their role. Members of primate groups often care for the young together and the society shares the responsibility of teaching them.
Some animals, such as dogs, can only see in black and white. However, primates can see in color, just as humans can. Primates have their eyes on the front of their heads like humans, which is called binocular vision. This gives them the ability to see depth. Primates are especially reliant on their eyes because their other senses are not as strong as some animals; they have short noses and less whiskers with which to sense their environment.
