Pauling
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
Researchers who study the relationship of organisms through DNA are primarily molecular biologists, geneticists, and evolutionary biologists. They analyze genetic material to understand evolutionary relationships, species classification, and the genetic basis of traits. This field often involves techniques like DNA sequencing and phylogenetic analysis to trace lineage and evolutionary history. These studies contribute to our understanding of biodiversity, evolution, and conservation efforts.
If two organisms are in the same phylum, it means they share a significant level of evolutionary relationship and exhibit fundamental structural and developmental similarities. Phyla are major taxonomic groups that categorize organisms based on key characteristics, such as body plan and organization. This classification indicates that the organisms likely diverged from a common ancestor relatively early in the evolutionary timeline. Thus, being in the same phylum suggests a broad connection in the evolutionary history of those organisms.
evolutionary changes in organisms
The study of the relationship of organisms through DNA is primarily conducted by evolutionary biologists and geneticists. They analyze genetic sequences to understand evolutionary relationships, biodiversity, and the mechanisms of evolution. This field often involves techniques such as phylogenetics, which uses DNA data to construct evolutionary trees that depict the relationships among species. Additionally, bioinformaticians play a key role in processing and analyzing the vast amounts of genetic data generated in these studies.
Pauling
The most accurate evidence of an evolutionary relationship between two organisms is the presence of shared genetic similarities, specifically in their DNA sequences. This indicates a common ancestry and evolutionary history between the two organisms.
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.

Cladograms tell you which animals are the closet in relationship, which are the farthest, what characteristics the animals have in common, what characteristics they would need to have in order to be closely related to them, and the number of shared characteristics between the animals.
The evolutionary relationship of a specific species to other organisms on a phylogenetic tree node shows how closely related that species is to other organisms based on their common ancestry. The closer the species is on the tree node, the more closely related they are in terms of evolution.
The evolutionary relationship of a specific species to other organisms within a phylogenetic tree node shows how closely related they are in terms of their common ancestry. The closer the species are on the tree, the more recent their shared ancestor.

I think you mean phylogeny. Phylogeny is the evolutionary history of a species or group of related species.
I don't really know that one I will have to look it up and put it up here
The separation of archaebacteria into a separate domain suggests that they have a distinct evolutionary history and are not closely related to other organisms in the traditional bacteria domain. This indicates that archaebacteria have unique characteristics and may have diverged early in the evolutionary timeline.
Taxonomy is abranch of biology that deals with classification and naming of organisms while Systematics deals with classification as well as traces there evolutionary history and evolutionary relationship.
