Pauling
ecology, epidemiological studies
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
population is the primary evolutionary unit of any living organisms
evolutionary changes in organisms
Systematics is the scientific study of the diversity of organisms and their evolutionary relationships. The science of naming, classifying, and describing organisms is called taxonomy.
Pauling
scientists can infer how closely related the organisms are in an evolutionary sense
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.
Charles Darwin was the first evolutionary biologist who championed the theory of natural selection.
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.
ecology, epidemiological studies
They see similarities with structures between modern day organisms and older organisms.

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
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.
population is the primary evolutionary unit of any living organisms
