What is the significance of the classification of the genera and species of the family species

Genus and species of the family of the Phylum of Man.

As follows: the kingdom is the animal kingdom; The phylum is the phylum Chordates.

The subphylum is a subphylum of vertebrates; The class is mammalian class; The subclass is the subclass of the true beast; The order is primate.

Science is a human science; genus is a genus of people; The species is Homo sapiens.

"Phylum genera and species" belong to taxonomy, which is the branch of biology that studies the methods and principles of taxonomy. Taxonomy is to follow the principles and methods of taxonomy to name and rank various groups of organisms. The "genus and species of the family of the Phylum Compendium" that we often refer to are the seven main levels in taxonomy, the species (species) are the basic units, the closely related species are grouped into genera, the genera are grouped into families, the family is subordinate to the order, the order is subordinate to the class, the class is subordinate to the phylum, and the phylum is subordinate to the kingdom.

1. Boundary.

For a long time, kingdom was the highest category in the biological science taxonomy. In the beginning, man divided living things into two kingdoms: animal and plant.

After the discovery of microorganisms, they were also classified into the animal or plant kingdom for a long time: active microorganisms were classified into the animal kingdom, pigmented (algae) or bacteria were classified into plants, and some were even placed into both kingdoms at the same time.

Later, bacteria without a nucleus were separated into a separate kingdom, and later fungi were separated from the plant kingdom and became an independent kingdom, and finally archaea were established as a kingdom on their own.

According to the originally accepted classification of the Six Realms, organisms are divided into the kingdom Viral, Prokaryotic, Fungi, Protists, Plants and Animals.

The latest genetic studies have found that this taxonomy is not quite correct, so domains have been introduced as the highest category of organisms. Existing organisms are classified into non-cellular biotic domains, eukaryotic domains, or prokaryotic domains, and organisms without a nucleus (bacteria and archaea) are classified into prokaryotes.

Only in eukaryotes there is a bounded division. There are four kingdoms in eukaryotes: the protists, fungi, plants, and animals. There are nine realms in total:

Viroids, Virions, Archaea, Bacteria, Cyanobacteria, Protists, Fungi, Plants, Animals.

2. In phylum biology, organisms with the most basic and significant common characteristics are divided into several groups, each group is called a phylum, such as protozoa, gymnosperms, etc. The following is the outline.

3. The outline is under the door and above the eye. Sometimes there is a general program and a sub-program. For example, mammals (belonging to the kingdom Animalia, chordates, vertebrate subphylum, under the order Carnivores, odd hoofs, artiodactyls, etc.), monocotyledons (belonging to the kingdom of plants, seed plants, angiosperms subphylum, under the duck grass subclass, Poaceae, etc.).

4. There are classes or subclasses under the headings, and there are families under them. There may also be general orders and suborders. For example, Carnivora (belonging to the kingdom Animalia, Chordates, subphylum vertebrates, mammals, under the felines, bears, canines, pandas, etc.), sedge (genus Plantae, seed plants, angiosperms, monocots, duck grass subclass, Poaceae, sedge family, etc.).

5. The family is located between the order and the genus. There are humans, cruciferae, monkeys.

6. The genus belongs to the family, and its purpose is to classify the organisms in the "order" in detail. For example: Macaque, Brassi, Man.

7. Species, also known as species, is the basic unit of taxonomy, which is located at the last level of taxonomy, under the genus. A more general concept refers to a group of related organisms that are more or less morphologically different from other such groups and are capable of mating and reproducing and having fertile offspring.

Man: Animal kingdom.

Humans belong taxonomically to: Animalia, Chordates, Mammalia, Primates, Hominidae, Homo sapiens, Homo sapiens.

The taxonomic units from large to small are kingdoms, phyla, classes, orders, families, genera, and species. The boundary is the largest taxonomic unit, and the most basic taxonomic unit is the species; The larger the taxonomic unit, the less similar the organisms, the fewer common features, the more species of organisms are included, and the more distant the relatives of the organisms; The smaller the taxonomic unit, the greater the degree of similarity of the organisms, the more common traits there are, the fewer species of organisms included, and the closer the kinship of the organisms.

Features Introduction:

In anthropology, human beings are defined as beings who are capable of using language, have complex social organizations and technological developments, and are especially capable of building groups and institutions to support and assist each other.

Paleoanthropologists see upright walking as an important factor in human evolution and an important symbol of human birth. For example, the inevitable consequence of walking upright is the division of hands and feet, which allows humans to use tools flexibly. Another example is that after walking upright, the field of vision is broadened, which helps the development of the brain and promotes the development of human intelligence.

The classification of genera and species of the phylum of human beings is as follows: eukaryotic general kingdom, animal kingdom, metazoan subkingdom, posterior mouth animal phylum, chordate phylum, vertebrate subphylum, amniotic general mammalia, euzoan subclass, primate, ape, narrow-nosed monkey suborder, ape superfamily, hominidae, hominidae, hominidae, homininus, homo sapiens.

Human Development:

After the end of the transition from ape to man, the human physique continues to develop.

Over a long period of time, people divided this development process into three stages: ape-man, ancient, and new-man.

Due to the continuous enrichment of fossil materials and the deepening of people's understanding, this staging method is no longer suitable.

There are two main staging methods used by foreign scholars. First, it is divided into three stages: Australopithecus, Homo erectus, and Homo sapiens; Homo sapiens is further divided into early Homo sapiens and modern Homo sapiens.

The disadvantage of this division is that it puts Australopithecus australopithecus who cannot make tools and Homo 1470 who can make tools in the same category.

The other is divided into three stages: Homo erectus, Homo sapiens in the early Zhenla period, and modern Homo sapiens. Chinese scholars have also proposed four stages of division, namely early ape-man, late ape-man (Homo erectus), early Homo sapiens, and late Homo sapiens.

The "early ape-man" stage is equivalent to the "earliest human (hominus)" stage proposed by foreign scholars. Although few fossil materials have been found before the Homo erectus, it is still appropriate to classify it as a separate stage to distinguish it from Australopithecus and Homo erectus. <>
