Are interpretations of a single data tree analysis conclusive enough? Can it accurately describe the evolution and relationships of taxa studied?
Phylogenetic tree or evolutionary tree are branched diagram or tree representation of evolutionary relationship between various life form and their various species i.e. phylogeny, classified on the basis of their similarities and dissimilarities with each other. The life form on earth can be drawn in single phylogenetic tree showing its all evolutionary history. The tree form represents the classification of life from lower to higher form of organisation.
Among many type of evolutionary tree as rooted, unrooted and so on, we can take example of rooted phylogenetic tree. Rooted phylogenetic tree have nodes whose branches represent the closedt ancestor and farthest is least common ancestor. similiar to the tree, this phylogenetic tree has root which represents the parent ancestor. the length of branch representys the time estimated. Similiarly, Unrooted trees only tells the relativity of the leaf nodes and do not require the ancestral root to be known.
yes, single phylogenetic tree analysis can be enough to conclude the evolutionary and relationships of different phylas and taxas.
