DNA analysis is commonly used to determine the similarity between two species. From this, we can infer the evolutionary relationship of those species.

What evidence do scientists use to make phylogenetic trees?
Phylogenetic trees represent hypotheses about the evolutionary relationships among a group of organisms. A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups.
What are 3 pieces of evidence that scientists combine to determine evolutionary relationships among species?
Genetic features, morphological features and behavioural features.
The differences between the taxonomy of a given group and its phylogeny?
Taxonomy is the science of naming and classifying organisms. It is done by looking at shared characteristics, such as morphological characters, against the background of biological diversity. It also takes phylogenetic relationships and DNA evidence into account.A phylogeny is the evolutionary history of a species or group of species. They separate organisms by evolutionary relationships (clades), based on comparative cytology and the comparison of DNA, morphological characters, and shared ancestral and derived characters.
Do Linnaeus Used Similarities in Structure to Determine Relationships Among Organisms?
yes
HOW ARE THE AREA OF STUDY -EVOLUTION AND CLASSIFICATION-INTERLINK?
Evolutionary relationships are traced in the classification of organisms. For classification of organisms, we look for similarities among organisms which allows us to group them. The more characteristics two species will have in common, the more closely they are related. It indicates that more closely two species are related, the more recently they would have had a common ancestor. Thus, classification of species is in fact a reflection of their evolutionary relationship.

Phylogenetic systems of classification attempt to reflect what type of relationships among species?
evolutionary
What is phylogeny?
I think you mean phylogeny. Phylogeny is the evolutionary history of a species or group of related species.
Why is the gene coding for ribosomal RNA or rRNA used for establishing phylogenetic relationships?
rRNA genes are actually conserved among species, they do not largely vary for each different strain or the subtypes of the same species! hence we are using rRNA sequences to identify the bacterium and place them on phylogenetic tree accordingly.
Phylogeny refers to what aspect of individuals?
Evolutionary relationships
How do you determine the evolutionary relationships among species?
examining the fossil records.
What sources of information are used to determine the relationships among different species Which provides information at the species level?
One source of information that is used to determine the relationships among different species is DNA. DNA bar coding and macroevolution research provide information at the species level.
What is phylogenetic skills?
For humans, a motor skill that is common among all cultures.
What species does the grey whale have a parasitic relationship with?
The grey whale has a parasitic relationship with whale lice, which grows on the back of grey whales, among the barnacles.
How do scientists determine the evolutionary relationship among species?
They use a taxonomic map to help classify organisms. The placement of organisms on this was originally based on similarities between species. Today we are able to look at their actual genes, which has resulted in a better understanding of evolutionary relationships - or the lack of them- and has resulted in some re-classification.
What are 3 pieces of evidence that scientists combine to determine evolutionary relationships among species?
Genetic features, morphological features and behavioural features.
Why would you infer that two species that look similar share a common evolutionary history?
scientist compare body structures development before birth and DNA sequences to determine the evolutionary relationship among organisims
