Based on Darwin's theory, the ape is the progenitor of man. Man and ape have a common origin, but as a result of different directions of development, today they are so significantly different.
Monkey is a representative of the order of humanoid primates. Its main habitat is tree crowns.
Man is a subject capable of influencing the environment. He is active, independent, his decisions are strong-willed and deliberate.
Let's consider what are the main differences between humans and monkeys:
The human spine is characterized by forward bends and backward bends. A man, unlike a monkey, has wider pelvic bones and a voluminous chest. He has a vaulted foot, which prevents the shaking of the internal organs during movement. All limbs are in harmony with the body.
Due to the fact that the thumb on the hand is opposed to the rest, a person is able to perform more operations with his hands than a monkey.
The spine in monkeys has the shape of an arc. Almost all species of monkeys, even from a distance, do not resemble humans in their structure, the only exceptions are chimpanzees. The body of the monkey is covered with hair, the arms are excessively long, and there are no calves on the legs. The front of the skull protrudes strongly forward.
The structure of the teeth
Adapting to the peculiarities of the external world, the way of human nutrition changed significantly . The need to use canines disappeared, and they gradually began to decrease in size and volume, and the spaces intended for closing canines in primates disappeared.
The shape, inclination and surface of other teeth have changed. The front teeth in humans are somewhat rounded, the lateral ones have an outward extension. Since there was a change in the teeth, the general appearance of the skull also underwent some transformations.
The jaw of a monkey is similar to that of a human, but is easily identified by the presence of canines and a U-shaped dental arch.
The state of the brain
The human brain is larger than that of a monkey, which puts it in a special position relative to other primates. In addition, the number of nerve cells and their location are also different for them.
A person has two signaling systems with the help of which he can create images, make plans for the future and subsequently implement them.
Method of movement
In the course of evolution, man acquired the ability to move on his lower limbs, straightening his back. This made it possible to free your hands. Now they were involved in a labor process in the course of which dexterity and skill were developed.
The main mode of movement for primates is on all fours and climbing. There are some species of monkeys that partially practice upright walking, such as gorillas. However, their stay in a horizontal position is short, from time to time, when moving, they lean on the back of the palms.
- The human brain is larger in size and more developed.
- Man has the ability to walk upright.
- There is no hair on the human body, and the arms are shorter than the legs.
- A person, in addition to the first signaling system, has a second one.
- Man owns consciousness.
