हिन्दीConsider the following statements regarding taxonomic categories and hierarchy: I. Systematics includes identification, nomenclature, classification, and takes into account evolutionary relationships between organisms. II. A 'taxon' represents a unit of classification and is merely a morphological aggregate rather than a distinct biological entity. III. 'Insects' represent a taxon at a specific rank because they possess recognizable concrete features such as three pairs of jointed legs. IV. The lowest category in the taxonomic hierarchy for both plant and animal kingdoms is 'Genus'. Which of the above statements are correct?
Correct answer · Option 1
I and III only
Explanation
Systematics considers evolutionary relationships in addition to identification, nomenclature, and classification. Taxa are distinct biological entities (not mere morphological aggregates), and species (not genus) is the lowest taxonomic category in the hierarchy.
