Why Classification Systems Keep Changing — NEET Biology

Correct answer: B — S3 and S5 only

This question evaluates the understanding of the definitions and scope of classification, taxonomy, and systematics based on NCERT. S1. Correct. NCERT states, "Classification is the process by which anything is grouped into convenient categories based on some easily observable characters." (Page 5, 'The Living World'). S2. Correct. NCERT mentions, "The scientific term for these categories is taxa." (Page 5, 'The Living World'). S3. Incorrect. NCERT states, "The scope of systematics was later enlarged to include identification, nomenclature and classification. Systematics takes into account evolutionary relationships between organisms." The statement claims it's *without* evolutionary relationships, which is false. (Page 6, 'The Living World'). S4. Correct. NCERT states, "Hence characterisation, identification, classification and nomenclature are the processes that are basic to taxonomy." (Page 5, 'The Living World'). S5. Incorrect. The dynamic nature of classification systems is implied throughout the chapter and explicitly questioned in the exercises, for example, "Why are the classification systems changing every now and then?" (Page 9, Exercise Q2). This suggests they are not static. Therefore, statements S3 and S5 are NOT correct.
