NEET Zoology Question (2026) — Solution

Step-by-step solution

Embryological support for evolution was proposed by Ernst Haeckel based on the observation of certain features during the embryonic stage common to all vertebrates that are absent in adults. However, this proposal was disapproved after careful study by Karl Ernst von Baer, who noted that embryos never pass through the adult stages of other animals. Therefore, the embryological support as proposed by Ernst Haeckel is not considered valid evidence for evolution. Divergent evolution (homology), convergent evolution (analogy), and paleontological evidence (fossils) are all accepted evidences for evolution. Answer: Embryological support for evolution as proposed by Ernst Heckel
