A phylogenetic system of classification was proposed by jhon hutchinson.

Phylogenetic system of classification was proposed by John Hutchinson.

Explanation:
Phylogenetic system of classification is based on the evolutionary history of organisms and their relationships to one another. It aims to classify organisms based on their evolutionary relationships rather than their morphological or anatomical similarities and differences. The phylogenetic system of classification was proposed by John Hutchinson in the 1950s.

Hutchinson was a British botanist who was interested in the classification of plants. He believed that traditional methods of classification were insufficient and that a new approach was needed. He proposed the phylogenetic system of classification to address this need.

The phylogenetic system of classification is based on the principles of cladistics. Cladistics is the study of evolutionary relationships among organisms. It involves the analysis of shared characteristics and the construction of a cladogram, which is a branching diagram that shows the evolutionary relationships among the organisms being studied.

In the phylogenetic system of classification, organisms are grouped together based on their shared evolutionary history. Organisms that share a common ancestor are placed together in a group called a clade. The clade includes all of the descendants of the common ancestor, and only the descendants of the common ancestor.

The phylogenetic system of classification has become increasingly popular in recent years, as advances in molecular biology have allowed scientists to study the DNA of organisms and better understand their evolutionary relationships. It has also been applied to the classification of animals, fungi, and other organisms, in addition to plants.

In conclusion, John Hutchinson proposed the phylogenetic system of classification, which is based on the evolutionary history of organisms and their relationships to one another. This system has become increasingly popular in recent years and has been applied to the classification of a wide range of organisms.
