Among the most frequently used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known standard sequences are estimated using phylogenetic trees.
<h3>What is a phylogenetic tree?</h3>
Among the most commonly used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known reference sequences are estimated using phylogenetic trees.
A phylogenetic tree is a diagram that depicts the evolutionary relationships between organisms or groups of organisms.
Scientists consider phylogenetic trees to be evolutionary hypotheses because the proposed relationships cannot be confirmed in the past.
Thus, every individual of same species are related to each other, so scientists can analyze another specimen from the same species.
