Which scientist proposed that "embryo never pass through the adult stages of other animals"?

• A. Alfred Wallace
• B. Thomas Malthus
• C. Karl Ernst von Baer
• D. Ernst Haeckel

Hint:

Answer 1

The Correct Option is C

Karl Ernst von Baer, a pioneer in embryology, formulated Baer’s Law.
He proposed that the embryo of a species does not pass through the adult stages of other species, contradicting Haeckel’s theory of recapitulation.
Baer emphasized that embryos of different species resemble each other in early development but diverge as they grow.
