The endosymbiotic theory implies that certain organelles, such as mitochondria and chloroplasts, originated from free-living prokaryotes that were engulfed by ancestral eukaryotic cells. This suggests a more complex evolutionary history where horizontal gene transfer and symbiotic relationships played a significant role in the development of eukaryotic life. Consequently, phylogenetic trees must account for these unique evolutionary events, indicating that the relationships among organisms may not solely reflect vertical inheritance but also horizontal gene transfer and symbiosis. This reshapes our understanding of evolutionary lineage and the classification of organisms.

What implication does the endosymbiont theory have for phylogeny?
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.
How are binomial nomenclature and phylogeny?
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.
Organisms can now be grouped into categories that represent lines of?
phylogeny.
What is the name of branch of biology deals with extinct organisms?
phylogeny
Who said Ontogeny Recapitulate 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.
What is Phylogeny 2?
The theory and practice of classifying organisms.

Who created the recapiculation theory?
" Ontogeny recapitulates phylogeny. " Ernst Haeckel. Now considered incorrect.
What is an organism's evolutionary history called?
Phylogeny
How do you use phylogeny in a sentence?
A phylogeny is history of organisms and they have six kingdoms.
How are phylogeny and kingdom related?
Kingdom and phylogeny are related because they both have to do with facts about the organism.
What is the word for an organism's evolutionary history?
The word for an organism's evolutionary history is its phylogeny. Phylogeny represents the evolutionary relationships and history of a group of organisms.
What is organismal phylogeny?
The oldest use for phylogenies of genes is inferring organismal phylogeny (Fitch, 1996)
Why was the stab in the back theory a problem for the Weimar republic?
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.
Is it true that A scientific theory is a statement that describes what scientists expect to happen every time under certain conditions?
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.
What is the modeling of the phylogeny of a species?
cladistics
What is cladogram used to do?
model a phylogeny
