Why is taxonomy important? a. taxonomy allows scientists to analyze dna and rna sequences. b. taxonomy allows a better understanding of relationships among species. c. taxonomy allows the manipulation of genes for medical purposes. d. taxonomy allows scientists to use both common names and domains of life.

The right answer is B.

The challenge of taxonomy is to reflect the succession of ramifications of the single tree of the living world. Grouping species, all the more closely as they are related, allows an understanding of the world, the origins of humanity and the diversity of life.

The current scientific classification is the phylogenetic classification still called "new classification". It is based on recent discoveries in genetics linking the genetic proximity of organisms to  their evolution.
