Question

Explain Biological Classification.​

Answer 1

Hello Brainly User

Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.

Hey brainly user!

Here is your answer....

1. Total number of animal species are 1.25 millions. A lot of variations occur in their structure and function. They exhibit great diversity in structure, habitat, habits and modes of life
2. So understand the interactions among highly diversified animal group a Systematic classification is needed which is biological classification
3. Father of taxonomy, founder of modern systematics was Carolous Linnaeus. He has introduced the system if hierarchical classification
4. Numerical taxonomy and phylogentic classification both of which are natural systems of classification emerged during 19 th and 20th centuries
5. Phylogentic classification is also called cladistic classification. It is an evolutionary classification and it explains how the common ancestry was scared by different animal groups
6. This classification emphasize on genetic distance between all species of phylogentic tree. This tree like diagrams for phylogeny was introduced by the Earnst Hackel
7. Cladistic classification considers the occur once of analogous classification by convergent evolution. Different organisms live in the same environment share these characteristics. Genetically they are distantly related ex:wings of sparrow and petagia of flying squirrels
8. It is also considered as homologous characters are functionally different from the structural plan and development. It is also called as divergent evolution
