When Carl Linnaeus initially developed the nomenclature system, he ranked kingdoms as the highest classification, but it was reduced in rank to domain in the 1960's.There are eight major classifications of scientific kingdoms. These are, Eubacteria, Archaebacteria, Archezoa, Protozoa, Animalia, Plantae, Fungi and Chromista.

What are the two major groups of organisms?
The two major groups of organisms are prokaryotes and eukaryotes. Prokaryotes are simple, unicellular organisms that lack a nucleus, while eukaryotes are more complex organisms with cells that contain a nucleus and other membrane-bound organelles.
Biologist classify animals into major groups called?
phyla?
What was developed by nutritionists to classify food into major groups?
The food pyramid.
What are the two major groups that scientists know about Bacteria?
The two groups are, Eubacteria and Archeabacteria.
How do scientists classify the earth's major physical characteristics?
Scientists classify the Earth's major physical characteristics based on factors such as its structure (core, mantle, crust), composition (rocks, minerals), and surface features (mountains, oceans, continents). These characteristics help scientists understand the Earth's geology, topography, and the processes that shape its landscape.
What do scientist use to classify all living things?
Hierarchical Levels (Taxonomic Ranks) Domain: The broadest category, which divides life into three major groups: Archaea, Bacteria, and Eukarya. Kingdom: Organisms are further divided into kingdoms (e.g., Animalia, Plantae, Fungi, Protista). Phylum: Groups organisms based on major body plans or structural similarities. Class: Further subdivision of phyla into groups sharing more specific traits. Order: Organisms within a class are divided into orders. Family: Orders are broken down into families that share even closer traits. Genus: Families are divided into genera (singular: genus), a group of species that are very similar. Species: The most specific level, referring to individual groups of organisms that can interbreed and produce fertile offspring.
What is the term to describe the major classification groups of organisms?
Taxonamy
What are the three major groups of organisms?
Archaea, Eubacteria, and Eukaryota
Biologists classify animals in the animal kingdom into about 35 major groups called?
Phylum
What are the three criteria used by scientists to classify an animal into one of the major phylum?
Scientists classify animals into major phyla based on three main criteria: body symmetry, which can be radial or bilateral; the number of tissue layers during embryonic development, distinguishing between animals with two (diploblastic) or three (triploblastic) layers; and the presence or absence of a body cavity, categorized as acoelomate, pseudocoelomate, or coelomate. These criteria help to categorize the vast diversity of animal life into systematic groups.
What is the only grouping of animals larger than a phylum in taxonomy?
The only grouping of animals larger than a phylum in taxonomy is the kingdom. Kingdoms are broad categories that classify organisms into major groups based on their overall characteristics and evolutionary relationships.
How have scientists been able to infer the relationship between the major groups of Vertebrates?
scientist have been able to infer the relationships between the major groups of vertebrates by bones
