One of the first scientists of the Renaissance to advance taxonomy through first hand observations was Aristotle.

God introduced the concepts that would lead to the science of taxonomy by commanding Adam to O feed the animals. O not eat the fruit of the tree of good and evil.

Carl Linnaeus was the famous 18th century Swedish botanist and naturalist who created the basic biological taxonomy — the so-called binomial classification system — that is the foundation of our modern taxonomic system.

Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, physician, and zoologist who formalised binomial nomenclature, the modern system of naming organisms. He is known as the “father of modern taxonomy”.

Living things are divided into five kingdoms: animal, plant, fungi, protist and monera. Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.

The current taxonomic system now has eight levels in its hierarchy, from lowest to highest, they are: species, genus, family, order, class, phylum, kingdom, domain. Thus species are grouped within genera, genera are grouped within families, families are grouped within orders, and so on (Figure 1).

Domain

The Animal Kingdom contains more than two million known species. The Animal Kingdom contains these seven Phyla: Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Arthropoda, and Chordata.

Five Kingdom Classification System

• Monera (includes Eubacteria and Archeobacteria) Individuals are single-celled, may or may not move, have a cell wall, have no chloroplasts or other organelles, and have no nucleus.
• Protista.
• Fungi.
• Plantae.
• Animalia.
• A “mini-key” to the five kingdoms.

Each kingdom is further subdivided into progressively smaller groups. The seven layers of subgrouping are Kingdom, Phylum, Class, Order, Family, Genus, Species. If you like mnemonics, “Kindly penguins commonly order fresh green sausage” is one way to remember this list.

Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. At one time, simple organisms such as amoebas and single-celled algae were classified together in a single taxonomic category: the kingdom Protista.

three domains

A domain in your life is an area in which you live and interact. We have four to five main domains in our life: personal, career, family, community, and spiritual community.

The Three Domain System, proposed by Woese and others, is an evolutionary model of phylogeny based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (rRNA), as well as the cell’s membrane lipid structure and its sensitivity to antibiotics. Comparing rRNA structure is especially useful.

Summary. That Bacteria, Archaea and Eukarya (eukaryotes) represent three separate domains of Life, no one having evolved from within any other, has been taken as fact for three decades.

According to the ‘three-domains tree’, the Eukarya and Archaea are more closely related to each other than they are to the Bacteria (Fig. 1).

There are three domains of life, the Archaea, the Bacteria, and the Eucarya. Organisms from Archaea and Bacteria have a prokaryotic cell structure, whereas organisms from the domain Eucarya (eukaryotes) encompass cells with a nucleus confining the genetic material from the cytoplasm.

It divides life into 23 main divisions in three domains: Bacteria, Archaea, and Eukarya.

The correct order of taxonomic categories, from most specific to broadest, is: species, genus, family, order, class, phylum and kingdom.

In biological taxonomy, a domain is the highest order of life classification, even higher than a Kingdom.

Protista is one kingdom in the domain Eukarya.
