Which type of anatomic structure are birds wings and human arms when compared to each other?
Homologous
Body parts similar in origin and structure are what?
homologous
Which would be homologous structure to a human arm bone?

Homologous structure that is greatly reduced in size is called?
A homologous structure that is greatly reduced in size is known as a vestigial structure. These structures are remnants of organs or body parts that had a function in ancestors but are no longer used in modern organisms. Examples include the human appendix and the hip bones in whales.
What is a homologous sturcture?
