Why is a “ring if life “ more appropriate to describe the relationship between archaea, bacteria, and eukaryotes than a “tree of life “?

A "ring of Life" is more appropriate to describe the relationship between archaea, bacteria, and eukaryotes than a “tree of life “, because each group of single-celled prokaryotic organisms produces something that is a necessity to another group of single-celled prokaryotic organisms. so therefor it is not like a tree of life which is more of a hierarchy than an everyone, and everything is equal Ring of Life.

The tree of life refers to a conventional model, which illustrates the origin of Eukaryotes and the relationship amongst the organisms. On the basis of this model, the Archaea and Eukaryotes are the sister lineages, as both descended from the bacterial ancestors.  

On the other hand, the ring of life is a present time model on the basis of which, the emergence of Eukaryotes took place due to the combination of two other domains, that is, Eubacteria and Archaea. The ancestors of Eubacteria and Archaea combined their genomes to produce the initial Eukaryote. That is, two distinct branches of the tree of life were combined to produce the ring of life.  

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
