Question

Biogenetic law is propounded by
a. Von Baer and Haeckel
b. Von Baer and Aristotle
c. Haeckel and Mendel
d. Mendel and Griffith

Answer 1

Hint: A theory of expansion and progression of animals is called the biogenetic law. It is known to be one of several recapitulation philosophies, which postulate that the phases of growth for an animal embryo are similar to other animals' mature periods or forms.

Complete answer:
We can say that the biogenetic law, which is known to be one of the recapitulation Theories and propositions, is proposed by Ernst Haeckel in Germany in the 1860s. he is the one who invented the study of ontogeny which restates phylogeny.

The word phylogeny includes the development of the person's emerging organism and young follows the conversion of progression of the classes. However, on the other hand, in the middle of the years of 1792– 1876, a scientist Baer Karl Ernst van Estonian was brought into the world of German scientists and embryologists.

Briefly, after ten years, he found the mammalian ovum and he followed its progression from the Graafian follicle to the emerging creature. Thus, the completion of the explanation of this theory was made by the scientist Baer Karl Ernst van Estonian.

The great Greek philosopher Aristotle was the one to create the two classification systems to assemble living organisms. Also, the scientist Griffith is famous for his well-proven Griffith’s experiment which states that the bacteria are proficient in shifting their genetic material through a procedure acknowledged as transformation. Moreover, Mendel was the person who gave the inheritance theory. However, they are not the ones who gave the biogenetic law.

Hence, the correct answer is option (A).

Note: In this replication theory, the scientists mentioned two terms, ontogeny and phylogeny. The ontogeny is the branch of science that normally deals with ontogenesis. The word Ontogenesis refers to the development of organisms. However, on the other hand, phylogeny is the branch of biology that deals with phylogenesis. The word phylogenesis is the process of evolution of organisms. Thus, we can say these terms have great importance in the biogenetic law.
