Question

What are the vestigial organs? Write two names of vestigial organs found in man.

Answer 1

Hint: Vestigial organs are believed to be remnants of organs. The study of vestigial organs offer an evolutionary explanation of such vestiges by stating that adaptations to the new environment of the organism have made these rudent. In human being about ninety vestigial organs are present

Complete answer: Vestigial structures are remnants of structures that used to function in our ancestors, but no longer function in our body. They are degenerated and dysfunctional. They are found in animals (humans) as well as in plants.
Examples of some vestigial organs in humans
-The human appendix is ​​the remnant of an appendix, a large functional structure located at the junction of the small and large intestines. Helps digest cellulose. This structure suggests that our ancestors ate only plant material for which the cecum played an important role. However, as it developed, this organ became smaller and more restless.
-In the inner corner of each eye there is a completely inextensible membrane called the nictitating membrane. In lower animals, it can be opened with the eyes when the animal is under water.
-The early stages of the human embryo have a short tail that decreases in size early in development.
-The outer earlobe is useless to humans, but may serve several functions for human ancestors.

Note:
Vestigial organs are found in many other organisms like -In snakes, the remnants of the hind legs and pelvis are attached to the flesh of the abdomen. In animals constantly living in deep holes, eyes develop quickly or do not develop. Birds that do not fly have small, broken wings. For instance; Ostrich, Emu, Kasu Lead Plants such as ruskus and asparagus turn leaves into thorns.
A person has about 90 imperfect organs. Vestigial organs existence can only be explained if they are perceived as useless and disappear. This evidence shows that animals and plants change and fertilize.
