The Moneran Kingdom
The kingdom placed at the bottom of the phylogenetic tree is typically the most ancient or primitive kingdom, which is Monera (bacteria). This placement reflects the evolutionary history and divergence of life on Earth, with more complex organisms branching off from simpler ones.
Porifera (sponges) is considered one of the most primitive phyla because they lack true tissues and organs, and exhibit a simple body plan without symmetry.
they show the least in kingdom and the most in phyla
The Kingdom Protista has the most members without structures for movement. This kingdom includes single-celled organisms such as protozoans and algae that may not have specialized structures for locomotion.
Typically, the classification level with the broadest scope, such as kingdom in biological classification or phylum in the animal kingdom, would have the most members because it encompasses multiple subgroups. These higher levels group together organisms with similar characteristics before further classifying them into more specific categories.
Archaeopteryx, the earliest and most primitive bird known, belongs to the Animalia Kingdom.
The Protista kingdom is often considered one of the most primitive groups of eukaryotic organisms, as it includes a diverse array of unicellular and simple multicellular life forms, such as algae, protozoa, and slime molds. However, the concept of "primitive" can be misleading; Protista is not a monophyletic group and encompasses organisms that have evolved various complex traits independently. While they may exhibit simpler structures compared to higher kingdoms, they also possess unique adaptations and evolutionary innovations. Thus, labeling Protista as the most primitive kingdom oversimplifies the complexity of evolutionary relationships.
An archaebacterium is a primitive bacterium-like organism in the kingdom Archaea.
most primitive
The most "primitive" protist in the Kingdom Protista would be the more ancestral protists. One major group of protists called the Excavates (which include the Diplomonads and the Parabasalids) are considered by some scientists as the most "primitive" because it lacks a mitochondria while other protists have mitochondria.
no..primitive is archaebacteria
It is as primitive as a cave man.

The word sought may be the taxonomic kingdom Archaea(primitive early microorganisms).
Yes it is the oldest and most primitive coding mechanism
scypozoans
No. marsupials are not considered primitive. They just have a different method of reproduction.
