PHENETICS. Phenetics is a scientific method of classifying organisms based on overall similarity, usually in morphology or other observable traits, regardless of their phylogeny or evolutionary relation.. 

Scene 4

Phenetics is a scientific method of classifying organisms based on overall similarity, usually 
in morphology or other observable traits, regardless of their phylogeny or evolutionary 
relation.

Phenetics starts with species or other taxa as operational taxonomic units (OTUs) and then 
clusters the OTUs on the basis of overall similarity, using an array of numerical techniques.

Cladistics is a scientific method to biological classification in which organisms are 
categorized in groups based on hypotheses of most recent common ancestry.

Cladistics involves the categorization of organisms based on shared traits/characteristics.

EVOLUTIONARY CLASSIFCIATION
EVOLUTIONARY CLASSIFICATION

Evolutionary classification is a method which is a sysnthesis of phenetics and cladistics. In 
this method, the goal is to group species into larger categories that reflects lines of 
evolutionary descent rather than overall similarities and differences. It uses phylogenetic 
techniques, analyzing genetic similarity between organisms to infer how closely one 
species or group is to another and also inferring the timescales of evolution.
The important difference between these two methods of taxonomic classification is that 
traditional evolutionary taxonomy sometimes accepts paraphyletic clades, while cladistics 
does not.

Classification and naming allows us to understand the diversity of fish species better. It 
helps us to learn about different kinds of fishes, their features, similarities and differences. 
Most importantly, classification and naming helps us organize fish species. Also, it is 
essential to give fish a standard name so scientists from different countries can talk about 
the same fish without confusion.
