Part One: How scientists classify organisms

Different organisms can be classified into categories based on the degree of difference in biological traits and the distance of genetic relationships.

Based on this principle, biologists divide existing organisms on the earth into: kingdom, phylum, class, order, family, genus, and species.

Species are the basic unit of biological classification. Arranging the various taxonomic levels in order of their level and subordination forms a hierarchical system of biological classification.

Understand the specific position of dogs in different taxonomic units

Animal kingdom: dogs, wolves, foxes, lions, orangutans, fish, birds, locusts, sea anemones, amoeba

Mammalia: dogs, wolves, foxes, lions, orangutans, fish

Carnivora: dogs, wolves, foxes, lions,

Canidae: dogs, wolves, foxes,

Canine genus: dog, wolf

Breed: dog

Features:

Note: 1) The smaller the taxonomic unit, the more common characteristics the organisms it contains will have, and the closer the genetic relationship will be; vice versa.

2) The fewer taxonomic units, the fewer taxa, and the fewer species it contains; vice versa.

Classification of living things PPT, part 2: the significance of biological classification

Classification according to the hierarchical method not only satisfies people's ability to identify organisms and utilize the evolution and development of organisms. This is of great significance to people's understanding of the evolution and development of organisms, as well as the introduction, domestication and cross-breeding of animals.
