Embryological support for evolution was disapproved by:
1. Alfred Wallace
2. Charles Darwin
3. Oparin
4. Karl Ernst von Baer
Answer:4. Karl Ernst von Baer
👉Embryological support for evolution was also proposed by Ernst
Heckel based upon the observation of certain features during embryonic
stage common to all vertebrates that are absent in adult.
👉For example,
the embryos of all vertebrates including human develop a row of vestigial
gill slit just behind the head but it is a functional organ only in fish and
not found in any other adult vertebrates.
👉However, this proposal was
disapproved on careful study performed by Karl Ernst von Baer. He noted
that embryos never pass through the adult stages of other animals.
