Animals are organisms with a number of life processes, just like plants. The science concerned with this is called zoology, which is timeless. Even the ancient Greeks were concerned with it. Since Darwin there has been explanatory research such as the evolution, morphology and adaptability of organisms. The single-celled organisms also traditionally belong to this group, although that does not seem logical and opinions are divided about it. The division and division of the animal world looks very impressive thanks to evolution. Is man the last link?

The boundary between plant and animal
Animals can be said to be apparently more independent of the environment in which they live than plants. The adaptation to temperature differences is a good example. The biggest difference, however, is that animals do not generate their energy through it photosynthesis. Under the influence of light, plants are able to make their own food from nutrient salts, minerals, water and carbon dioxide. Animals lack that ability.
Fungi
In general, only multicellular organisms are considered part of the animal kingdom in science. Traditionally, however, this also includes single-celled organisms. Whether that is biologically justified? Opinions are still divided on it. An example of this is the fungus (sister group of the animal kingdom).
Transitional forms
There are many transitional forms in biology. Some living things can make food from minerals with the help of green leafy green granules and light. At the same time they have an eye spot, with which they catch light. Just like the animals. They also move with whip or cilia.
Organisms
To give an example: the sea anemone is a species of sea anamon and resembles a flowering one plant, but is an animal. Taxonomically, the sea anemone is classified with the Cnidarians (Cnidaria) and the class of the flower animals (Anthozoa). The beautiful ?? leaves ?? its tentacles. Partly because of this, it is often difficult to determine whether an organism belongs to the animal or plant kingdom.
Is man an animal?
Biologically yes. This is also clearly evident from behavioral research and animal communication. This also applies to abstract thinking. However, the development of a so-called high culture is typically a human gift ?? although? As research in the animal world continues, that line is likely to fade too. Scientific-biological seen, the distinction between humans and animals is decidedly arbitrary.
Traditional, simplified division of the animal kingdom
Charles Darwin (1809-1882) published in 1859 On the origin of species by means of natural selection (Origin of Species). His theory had and still has a major influence on social and social thinking. At the time, the work caused one landslide especially in philosophy and religion. Zoology is a branch of biology that studies the animal kingdom. The animal kingdom that consists of many subgroups, divided into tribes.
Invertebrates
Invertebrate means that these animals do not have a central strand that provides strength to the body.
- Unicellular animals: Single-celled organisms are microscopic in size.
- Sponges: Have a skeleton of needles between the cells.
- Cavity animals: Their body is characterized by a bag-shaped whole. Sweep with their tentacles ?? they eat food.
- Flatworms: Very primitive worm. Usually they live parasitically, just like the roundworm.
- Ringworms: These worms are articulated. So they consist of separate parts. The earthworm is an example of this.
- Crustaceans: The group of crabs and lobsters.
- Insects: The group with the most species. They have a three-piece body and six legs.
- Spiders: Belong to the arthropods with the previous two groups. Spiders have eight legs.
- Molluscs: Animals with a week’s body. They remove lime from the water with which to make their shell.
- Echinoderms: With the lime from the water they form skin spines, like the starfish.
Vertebrates
The vertebrates have a spinal column with a central nerve, or the spinal cord.
- Fishing: Tied to the water.
- Amphibians: Live both on land and in water.
- Reptiles: This group includes all animals that are dependent on the environment for their body temperature. This also applies to fish and amphibians.
- Birds: Poetically, they are lord and master of the air.
- Mammals: The most highly developed animals, including humans.
What Comes After Man?
An interesting question. After all, according to Darwin, man arose from the primate. Scientists are already looking for clues that indicate that humans are mammals. develops that rivals us in every respect, as we surpassed our predecessors. What will it be if man is not the last link? A creature some see in their dreams: with hydrocephalus. and wide-eyed, creatures that move into what is still considered today ufo ?? s considers? In other words, do these ‘dreamers’ see man’s distant future?
