Systematics differs from traditional taxonomy primarily because systematics explicitly includes which of the following dimensions in its study of organisms?

1. Only observable morphological features and local name comparisons.
2. Evolutionary relationships among diverse organisms along with identification, nomenclature, and classification.
3. Solely the biochemical analysis of floral characters for floral formula construction.
4. Characterisation based exclusively on the ecological uses of organisms for human welfare.
