Which is the highest genus and species of the Phylum family, which is the lowest

The realm is the highest, and the species is the lowest.

According to the characteristics of biological evolutionary kinship and morphological structure, modern biologists use seven levels to classify biological evolution, in order:

Domains, phyla, classes, orders, families, genera, species.

The highest in the world and the lowest in species are ranked from highest to lowest.

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.

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.

After the Swedish biologist Linnaeus named the organisms, later biologists classified them by domain, kingdom, phylum, class, order, family, genus, and species. The species is the most basic unit of taxonomic unit, and the family is the most commonly used unit of classification.

Linnaeus solved two key problems for taxonomy: the first was the establishment of a binomial system, in which each species was given a scientific name, consisting of two Latin pseudonyms, the first representing the genus name and the second representing the species name.

The second is the establishment of the order system, Linnaeus divided the natural world into three kingdoms of plants, animals and minerals, and under the animal and plant kingdoms, there are four levels: class, order, genus and species, thus establishing the order system of classification.

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. <>
