Do ants smell? Detailed answer
Directory / Big encyclopedia. Questions for quiz and self-education Did you know? Do ants smell? Ants are such interesting insects that we would need much more space than we can afford to tell about all the amazing features of their life. Therefore, we will limit ourselves to only a few of them. To begin with, let's say that ants can be found in the sands of deserts, and on the prairies, and on the sea coast, and on the slopes of mountains, and in forests - in almost all corners of the world, except perhaps for the tops of the highest mountains! They can live in almost any climate. There are thousands of varieties of ants, and they are all relatives of bees and bumblebees, that is, they belong to the same order of insects. All ants are social creatures. This means that they live in colonies. There are three types of ants in each colony: males, females (or queens), and worker ants. Males and females of almost all ant species have wings, but workers are always wingless. After her mating departure, the queen gets rid of the wings. Ant colonies can vary greatly in size. In some of them, only a few dozen of these hardworking workers live, in others - hundreds of thousands! Although ants differ considerably in size, they are more or less similar in appearance. A pair of long antennae, or antennae, hangs from the ant's head, they constantly sway and not only feel objects, but are also organs of smell. Therefore, although the ant does not have a "nose", it can smell. The antennae also help the ant to distinguish and communicate with its fellow tribesmen. An ant's head contains a brain, a pair of complex or compound eyes, strong jaws, and a mouth. In addition to compound eyes, most ants have additional organs of vision - simple eyes, or stemmas. The life cycle of an ant is very interesting. The females leave the colonies and rise high into the sky, the males follow them. After this mating flight, the males die almost immediately, and each female, or queen, flies away and establishes a new colony. She burrows into the ground, arranges a nest in this way and lays her eggs in it. After the eggs hatch into legless larvae, the queen helps each of them to spin a cocoon. When a young ant grows inside the cocoon, she tears one end of the cocoon and pulls the ant out. Almost immediately, these newborn worker ants begin their adult life, full of labors in arranging their common home - the colony and special care for the uterus, which in English is called the "queen".

When did civilization appear? Much time has passed since man has reached what we call a civilized society. At first, man, like animals, was in a wild state. He did not speak and ate only what he could find. Later, people began to live in groups, learned how to make fire, and even later they learned how to make tools and hunt. Man learned to make pottery for cooking, began to live in tribes, could move from one area to another. The next stage of human development, which was called the era of barbarism, showed that man had learned to grow food from seeds and tame animals. Then he began to smelt such metals as copper and iron, which made it possible to produce more advanced tools and build his own dwelling. The appearance of rock paintings can be considered the end of the era of barbarism and the beginning of the era of civilization. The invention of writing is considered the beginning of the era of civilization, as it allowed a person to record the events of the past. Thus, people could study the experience of their ancestors. This happened about 5-6 thousand years ago. By the time man has reached this stage of development, he too has improved in many ways. He developed agriculture and industry to the point where people could live in villages and even cities. There was management, trade, laws, there was also the migration of people. The earliest civilizations known to us from the history of civilization are Egyptian and Babylonian. The Egyptians invented writing 4500 years ago. They had a well-thought-out control system; they used mathematical calculations when building the pyramids; they had a calendar; skillful architects appeared; various mechanisms were used. About 4000 years ago, civilization developed on the island of Crete, and about 4500 years ago, the Sumerian civilization developed on the banks of the Tigris and Euphrates rivers.
