Question

Evolutionary classification is known as

Answer 1

Evolutionary classification system is based on the evolutionary ancestry like evolution of life and it shows the genetic relationship in organisms. This kind of classification is based on the descent on the common ancestry.

Complete answer:
The artificial system of classification is based on characters that are superficial, arbitrary and easily observed. Whereas when we talk about natural classification we use characters that are pertaining to morphology, cytology, anatomy, biochemistry etc. They are used to classify the organisms into homogenous groups of organisms that are related. Evolutionary classification is a branch of biological classification that seeks to classify organisms on the basis of phylogenetic relationship and the degree of evolutionary changes taking place.

We can also say that the classification that is based on the evolutionary relationship is referred to as phylogenetic classification or evolutionary classification. This kind of classification helps us to know ancestral relationships, the lineages and the evolutionary history of taxonomic groups for the process of classification. It arose from the Linnaean taxonomy that was generally given under the influence of the theory of evolution. The taxonomy of the Animal and Plant Kingdoms was formulated before Charles Darwin’s book named On the Origin of Species was published.

Evolutionary classification deals with the classification of the organisms by the use of taking into consideration of phylogenetic relationship or progenitor- descendant relationship and the degree of evolutionary changes taking place. It is also called a phylogenetic system because the classification of organisms takes place while considering the phylogenetic relationship that are in the organisms.

Hence, it is also called a phylogenetic system.

Note: Evolutionary taxonomy was made in contribution of 3 taxonomists named, Cavalier- Smith, G.G Simpson and Ernst Mayr. From the past few decades there has been a drastic increase in DNA sequencing that is done for reconstruction of phylogeny and there has been more emphasis from evolutionary taxonomy. Today scientists use molecular phylogeny to guide their research.
