Define and explain the following terms: $1$. Analogous organs,$2$. Vestigial or rudimentary organs.

(N/A) $1$. Analogous organs: These organs have a similar appearance and perform the same function,but they develop in totally different groups and are completely different in their basic structure and developmental origin. For example,the wings of a butterfly (chitinous),a bird (feathered),a Pterodactyl,and a bat (skin fold) all serve the same purpose of flight but differ significantly in their anatomical structure.
$2$. Vestigial or rudimentary organs: These are the useless remnants of structures or organs that were likely large and functional in the ancestors. Examples include the vermiform appendix in humans,the nictitating membrane,auricular muscles,the vestigial tail in vertebrates,wisdom teeth,mammary glands in males,and body hair.
