Explain Systematic - Modern Trends in Animal Taxonomy

Systematic is defined as the study of relationship among organisms which means reconstruction of phylogenies. It is that branch of biology which employs the techniques of other branches of biological knowledge like biochemistry, genetics. biophysics etc, for the comparative study of the interrelationships of groups of organisms. In other words, there are two parts of systematic. The first part is taxonomy which is concerned with identifying, describing and naming the various kinds of organisms. The second part is evolution which is concerned with understanding the origin of organisms in nature and the processes which tend to change or maintain them.
