Read the following two excerpts outlining distinct theories from different academic disciplines:
Excerpt A
According to Thomas Kuhn, scientific progress is not purely cumulative. Instead, disciplines spend long periods in 'normal science,' operating under a universally accepted paradigm that dictates which problems are legitimate. Over time, anomalies—observations that the current paradigm cannot explain—accumulate. Initially ignored or dismissed, these anomalies eventually induce a profound crisis of confidence within the scientific community. This crisis is resolved only through a sudden, discontinuous 'paradigm shift,' wherein an entirely new theoretical framework abruptly overthrows and replaces the old, redefining the discipline's fundamental boundaries.
Excerpt B
The theory of punctuated equilibrium challenges the view of steady, gradual evolution. It posits that species spend the vast majority of their geological history in morphological stasis, exhibiting essentially no physical change. However, as localized ecological stresses silently build over time, a population's existing physiological traits become increasingly mismatched with its environment. This growing evolutionary friction reaches a critical threshold, often manifesting as a sudden environmental cataclysm. This triggers a rapid, explosive burst of speciation in isolated populations. Consequently, novel descendant species emerge abruptly in the fossil record, completely superseding their ancestors.
Based on the structural analogies between the two chronological models presented, match each conceptual element from Excerpt A with its precise logical counterpart in Excerpt B.
