Step 1: Understanding the Concept:
Taxonomy is divided into three distinct conceptual levels based on the degree of evolutionary and systemic organization: Alpha, Beta, and Gamma taxonomy.
Step 2: Detailed Explanation:
Let us look at each level of taxonomy:
- Alpha Taxonomy: Deals with the basic step of identifying, naming, and characterizing species.
- Beta Taxonomy: Deals with the arrangement of species into a natural system of classification based on structural and phylogenetic relationships (lower to higher categories).
- Gamma Taxonomy: Deals with the study of evolutionary regimes, speciation rates, and intraspecific variations (evolutionary taxonomy).
Step 3: Final Answer:
Beta-taxonomy is concerned with the arrangement of species into a natural system of classification, corresponding to option (D).
