Question

Neoteny is found in……………..
A. Axolotl
B. Hyla
C. Salamander.
D. Tadpole.

Answer 1

Hint: The term neoteny is also known as juvenilization and it is a process in which an adult individual which bears some juvenile characteristics or features. Neoteny is also found in modern human beings. It is delaying somatic development.

Complete answer:
The organism holds the sexual maturity at the larval stage is said to be neoteny. Axolotl is known as walking fish which is an amphibious creature, not a fish and it is closely related to the salamander. This animal shows neoteny, which holds juvenile character and reaches adulthood without morphogenesis.
-Hyla is the genus of frog which shows complete morphogenesis and does not show a neoteny process.
-A salamander is a group of amphibious creatures which appear as reptiles or lizards with a slanderous body, blunt snout, short limbs and possess tail in both larval as well as the adult stage. This organism shows complete morphogenesis and does hold neoteny.
-Tadpole is the larval stage of the frog, the tadpole lives inside the water because it bears gills, fins, and tail-like features. Tadpoles develop into an adult frog individual through morphogenesis, so that this organism does not show neoteny.
Hence, the correct option is (A).

Note: Neoteny is found in modern humans and it is amplified in humans as compared to non- human primates. Adults have closely resembled infants of chimpanzees and gorillas. Neotenic features of the head show globular skull, thin skull bone, and reduction of bow ridges, the large brain with a flattened and broad face. The neoteny in the human body is shown by the hairless body and in genitalia the absence of pens bone and presence of hymen.
