How are Different Animals Related?

Zootaxonomy is a branch of zoology. It mainly studies the types of animals, the kinship between species, the origin and evolution of the animal kingdom, and so on. According to the shapes of animals in the nature, internal structure of the body, characteristics of embryonic development, physiological habits, and life. Comprehensive research on the geographical environment and other characteristics of animals is carried out. Animals with the same or similar characteristics are classified into a category and they are named. This is the research content of animal taxonomy. The animal kingdom includes chordae and invertebrates (invertebrates are divided into coelenterates, flat animals, linear animals, phytons, molluscs, arthropods, etc.).

Taxonomy

Knowledge of animal taxonomy is a necessary foundation for studying and studying zoology. ^[1]

From the Lin Nai era to the present, many different viewpoints have emerged in animal taxonomy. The journal "Systematic Zoolog" in the United States has been the subject of debates, which has led to an unprecedentedly active taxonomy theory and has rapidly promoted the development of the discipline. The taxonomic neighborhood can be divided into four schools.

1. Traditional taxonomy

This school represents older or traditional ideas and methods. Earlier taxonomists, while fully supporting and directly aware of the theory of evolution, felt that seeking

Imbalances in taxonomic studies

The above discussion refers to the entire history of the development of taxonomic disciplines, and specific to different animal species or different regions and countries, there is a great imbalance.

From different animal categories, vertebrates are better than invertebrates. Among vertebrates, birds and mammals have the highest level of research, and the main research work has entered the second and third stages of development. Among invertebrates, taxa that are economically important or easy to find, gorgeous or eye-catching, or hard and easy to preserve are often studied more, otherwise the research on seals has just entered the first stage of research. As far as insects are concerned, because of their small size and variety, the work of the first stage of development is far from complete, and many animals have disappeared from the earth before humans knew them.

Imbalances studied in different countries

In terms of different regions of the world, Western Europe's small and economically developed countries, such as Britain, Germany, and France, have the highest levels of research. Although the Soviet Union, the United States, and Canada have a long history and many personnel, due to their large size and complex natural environment, the domestic species have not been investigated clearly. Except for Brazil, Mexico, India, and Pakistan, which have a large number of national taxonomists, the classification work in most countries is still being studied by the staff of developed countries, and there are more types to be discovered.

China's animal taxonomy has made great progress since the founding of the People's Republic of China, both in academics and in serving production practices. But because of a weak foundation, development is very uneven. Taking insects as an example, there are still a large number of species in the blank state, and no one has conducted any research in China. Young friends, the future belongs to you. I hope that from an early age, you will make up your mind to fill the gaps in the taxonomy of our country's taxonomy, and use your ingenuity to catch up with the advanced world level as soon as possible.
