Question

name any two vestigial organs of human body​

Answer 1

Answer:

In the context of human evolution, human vestigiality involves those traits (such as organs or behaviors) occurring in humans that have lost all or most of their original function through evolution. Although structures called vestigial often appear functionless, a vestigial structure may retain lesser functions or develop minor new ones. In some cases, structures once identified as vestigial simply had an unrecognized function. Vestigal organs are sometimes called rudimentary organs.

The examples of human vestigiality are numerous, including the anatomical (such as the human tailbone, wisdom teeth, and inside corner of the eye), the behavioral (goose bumps and palmar grasp reflex), and molecular (pseudogenes). Many human characteristics are also vestigial in other primates and related animals.

Answer 2

Answer:

External ear: The outer rim of the ear which is known as the helix is a vestigial structure which is the underdeveloped muscle in the ear and is unable to bring about the movement of ears.

Nictitating membrane: Nictitating membrane is the third eyelid that is found in few animals which protect the eyes and keep them most which helps them in vision. It is replaced by plica semilunaris in humans.
