Question

explain the importance and applicationof biosytematics

Answer 1

Answer:

explanation:

The term systematics is derived from the Latinised Greek word and ‘systema’ means ‘together’. The systematics partly overlap with taxonomy and originally used to des­cribe the system of classification prescribed by early biologists. Linnaeus applied the word “Systematics” in the system of classi­fication in his famous book ‘Systema Natu­rae’ published in 1735.

Blackwelder and Boyden (1952) gave a definition that “sys­tematics is the entire field dealing with the kinds of animals, their distinction, classifica­tion and evolution”. C. G. Simpson (1961) considers that “Systematics is the scientific study of the kinds and diversity of organ­isms and of any and all relationships among them”.

Application of Systematics in Biology:

1. Systematics is the study of diversity of organisms including past and present and relationships among living things. Relationships are established by mak­ing cladograms, phylogenetic trees and phylogenies. The phylogeny is the evolutionary history of an animal or plant, for a taxonomic group.

Phylogenies include two parts—the first part shows the group relationships and the second part indicates the amount of evolution. Phylogenetic trees of species and higher taxa are established by morphological, physi­ological and molecular characteristics, and the distribution of animals and their ancestors are related to geogra­phy. In this way the systematics is used to understand the evolutionary history of organisms.
