Question

Select the correct system of classification among the following which is based on the evolution, order and ancestry.

• A. Natural System
• B. Analogous System
• C. Phylogenetic System
• D. Homologous System

Answer 1

The correct option is C Phylogenetic System

Analogous relationships focus on function like the similarity of function and superficial resemblance of structures that have different origins.

Homologous relationships focus on organs having similar structure but not the same function in different organisms suggesting a common ancestry or evolutionary origin.

Natural System of Classification is based upon morphological and anatomical characteristics and affinities considered in the light of phylogeny and embryology specifically.

Phylogenetic System of Classification is based on the evolutionary trends, order and ancestry of the organisms.
