HISTORY OF TAXONOMY

HISTORY OF TAXONOMY:-

The history of plant taxonomy can be study in 4 phases.


1) Explotrary phase
2) Consolibation phase
3) Bio-Systematic phase
4) Holotaxonomic phase

1) Explotrary phase:-

a) Theophrastus:- Published a book enquiry in to plant.

b)  The first herbarium was specialized 1533 in Padva Italy.

c)  Bubhin, John Ray they have concept of species synonyms classification and nomenclature.

d) Linn:- Species plantarum and introduced bionomial nomenclature.

2) Consolibation Phase:- 

The phase worked by publication a number of monomental works on plant classification.

a) De-Kendulle:- Modified Linn.  Classification

b) Benthem and hooker:- Published genera plantarun and introduced natural system of classification.

c) Charles darvin(1859):- Published a book the origin of species.

d) Dobzhansky:- Published biological species concept.

e) Engler and Prantl(1937):- Suggested semi phylogenetic system.

f)  John Hutchinsion:- He gave 24 principle of phylogeny published a book Family of flowering plants 1959.


g) Takhtajan:- Origin and dispursal 1969.

h) Cronquiest:- In immunation and classification of flowering plants.
Technique of herbarium preparation and presentation.

3) Bio-Systematic Phase:-

a) Huxley(1940):- 

Purposed the term new systematic phase.

b) Camp and Gilly(1943):- 

Purposed the term Bio-Systematic to new systematic.
The development of many technique like paper chromatography detains, and sequences of amino acids DNA and RNA.

4) Holotaxonomic Phase:- 

Collection of data analysis and synthesized numerical taxonomy is known as qualtative taxonomy.
