Question

The example of recapitulation theory is
a. Embryonic membranes of reptiles
b. Tadpole of frog
c. Placenta of mammals
d. Canine teeth of dog

Answer 1

Hint: The recapitulation theory is also called as biogenetic theory, previously the scientist by the name Ernst Heckle states a line called “ ontogeny recapitulates phylogeny” which means that where an animal undergo a lot of changes from the fertilization, and its states that these stages resemble the adult stages of their ancestors in the evolution.

Complete answer:
> It is also known as Meckel – Serres law
> Ontogeny refers to various stages of the organism, in the process of development from the individual cell to Mature individuals, and it is believed that these stages are similar to some of the adult stages of the ancestors.
> Phylogeny mainly tells about the evolutionary relationships between different species and the entire entity, where it is drawn in the form of a phylogenetic tree.

Recapitulation theory applications:
- This theory is applied in various fields and relevant areas such as field art.
- In the case of field art, this principle is applied to create and recast the art history.
- In the field of cognitive development.

So from the above options Tadpole of the frog is an example of this theory

The reason is why it comes under the example is that tadpole is one of the embryonic stages of the frog, during this stage, it exactly resembles like tailed fish, where it respiration is through gills, and from this one can say that frogs arise from fish, and fish are the ancestors of a frog.

Hence, The correct answer is option (B).

Note: Recapitulation theory itself has been viewed in the field of historical biology and it’s development rather than dogma, tadpole of a frog is the best example, gills are present in the larva stage of frog but absent in the adult form.
