(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Ernst Haeckel’s biogenetic doctrines underpin evolutionary developmental biology, distinguishing recapitulation from related concepts. The correct answer is option (1): (A)-(IV), (B)-(I), (C)-(II), (D)-(III) [ from prior context].
Statement Matching
Ontogeny repeats phylogeny (A) – Doctrine of recapitulation (IV): Haeckel’s core idea states embryonic development (ontogeny) mirrors ancestral evolutionary history (phylogeny) [conversation context].
An abnormality is a reminiscent of a remote ancestor (B) – Doctrine of teratology (I): Abnormal developments recall ancestral forms, linking pathology to phylogeny.
Serial arrangement of organisms depicting gradation in a trait (C) – Doctrine of sequences (II): Organisms arranged linearly show trait progression, reflecting evolutionary steps.
In a derived trait, the primitive condition is similar to ancestral structure (D) – Doctrine of association (III): Primitive states in advanced traits resemble ancestors, tying development to origins.
Option Breakdown
-
(1) (A)-(IV), (B)-(I), (C)-(II), (D)-(III): Correct; matches Haeckel’s doctrines precisely.
-
(2) (A)-(II), (B)-(III), (C)-(IV), (D)-(I): Wrong; swaps recapitulation with sequences.
-
(3) (A)-(I), (B)-(II), (C)-(III), (D)-(IV): Wrong; misaligns ontogeny with teratology.
-
(4) (A)-(III), (B)-(IV), (C)-(II), (D)-(I): Wrong; confuses association and recapitulation.
Ontogeny repeats phylogeny doctrine of recapitulation matching clarifies Haeckel’s evolutionary theories for biology competitive exams. List I concepts pair with List II doctrines explaining development, abnormalities, sequences, and ancestral traits.
Haeckel’s Doctrines Explained
Haeckel proposed four doctrines linking embryology to evolution. Recapitulation remains foundational despite modifications [conversation context].
