The endosymbiont theory proposes that organelles like mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by a host cell and developed a symbiotic relationship. This has implications for phylogeny as it suggests that certain organelles have a different evolutionary history than the rest of the cell, leading to the concept of lateral gene transfer and complicating the interpretation of evolutionary relationships based on traditional phylogenetic methods.
Binomial nomenclature and phylogeny both have to do with organisms. The former refers to the modern scientist's system for naming organisms. The latter is about how an organism evolved over time.
phylogeny.
phylogeny
This statement means that the development of an individual organism (ontogeny) summarizes the development of the entire group of organisms (phylogeny). In other words, when we look at the stages of embryonic development of a human being we can see the stages of the evolution of mammals. The embryo starts as a single cell organism, changes to multicellular, develops gill arches, a single chamber heart that changes to a multichambered heart, etc.. Evolutionists theorize that these are the same stages in evolution.
The theory and practice of classifying organisms.

" Ontogeny recapitulates phylogeny. " Ernst Haeckel. Now considered incorrect.
Phylogeny
Phylogeny is the study of evolutionary relationships among organisms.
Kingdom and phylogeny are related because they both have to do with facts about the organism.
The word for an organism's evolutionary history is its phylogeny. Phylogeny represents the evolutionary relationships and history of a group of organisms.
The oldest use for phylogenies of genes is inferring organismal phylogeny (Fitch, 1996)
The implication of the stab-in-the-back theory was that the pro-Republic parties and politicians had # Stirred up discontent, strikes, and fomented revolution in Germany in 1918 # Asked for an armitice unnecessarily # Signed a devastating peace treaty In other words, the implication was that these politicians were traitors.
A scientific theory presents an explanation for a phenomenon. Using that explanation, one can then make predictions about what will happen under certain conditions. But the prediction is not the theory, it is a implication of the theory.
