Explain the term evolutionary tree

Explain the term evolutionary tree? Is there an accurate evolutionary tree known by science which describes the emergence and origin of each and every kind of living being?

Evolutionary tree is the schematic and pictorial representation of evolutionary relations among species of living-beings in which the trunk (or preceding branch) symbolizes common ascendants of species and classes of living beings which are distributed all along its branches according to hypothesis on their origin. For illustration, today it is admitted that mammals and birds are two distinct branches of similar preceding reptile branch.

Biology can’t assure a definite evolutionary tree (or phylogeny) on the species of living-beings that live or encompass lived in our planet. There are numerous data to be discovered and lots of knowledge gaps to be filled. One of the most promising techniques to study phylogeny is the comparison of DNA molecules from various groups of living beings researching similarities and differences in the nucleotide sequences which may point out more or less relatedness between species.
