Explanation:
Systematics is the science of classification and phylogeny reconstruction. Studies diversity as a consequence of evolutive history and establishes the bases to reconstruct biological patterns and formulate hypotheses to explain the processes of these patterns. It reconstructs the origin and diversification of a taxon. Systematics creates systems of classification represented in a tree. Taxonomy is based on systematics. 
The main goal of systematics is to solve the genealogical relationship between different species and biological groups that produces natural clusters. 
 Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.
