Question

Phylogenetic classification is based on

A. utilitarian system
B. habits
C. overall similarities
D. common evolutionary descent  
Answer :   common evolutionary descent
Solution :
The first phylogenetic system of classification was proposed by Adolf Engler and his associate Karl Prantl in their monograph “Die Naturlichen Pflanzen Familien”. In this system of classification, organisms are classified on the basis of evolutionary sequence and genetic relationship among the organisms. Hence, this system is highly dynamic not static.
Note : Fossil records play a vital role in elucidation of evolutionary relationships. This system has led to new systematics.
