Question

How is cladistics different from Linnaean taxonomy?

Answer 1

Hint: The classical taxonomy is based on observable morphological characters whereas modern taxonomic studies are based on some essential features like study of both external and internal structure of organisms along with their cell structure, development process and ecological information of organisms.

Complete answer:

Linnaean taxonomy	Cladistics.
In this type of taxonomy species is considered as basic unit or can be called as fixed entity	In this type of classification species is considered and said to be the dynamic entity
It is known as old taxonomy	It is known as neo systematics mean new taxonomy
Morphological features are taken into the account.	Biological feature that is both internal and external features are taken into account
This taxonomy does not include evolutionary relationship of organisms	This taxonomy includes in it the evolutionary relationship of organisms
The studies are more preferable on the species	The studies are preferable on the sub-species and the population
This taxonomy is based on PR Darwinian period	This taxonomy is based on the post-Darwinian period

Human beings had not only studied different kinds of organisms but also tried to find out relationships among them. This led to the development of a new branch of study in the science field, known as "Systematics". The word systematics is derived from Latin word "Systema" which means systematic arrangement of organisms. It was first used by Carolus Linnaeus in the title of his book published as "Systema Naturae".
Note: Systematics is a wider field of science as with identification, nomenclature and classification, it also takes into account evolutionary relationships between various organisms. "Systematics" is the science which deals with diversity of organisms and all their comparative and evolutionary relationships.
