Question

structures like the human tail bone are called vestigial structures.
true
false

Explanation:

Vestigial structures are remnants of organs or structures that had a function in an early ancestor. The human tail bone (coccyx) is a vestigial structure as it is a remnant of a tail that our ancestors had, and it no longer serves the same purpose (or has a greatly reduced function) in humans. So the statement is true.

Answer:

TRUE
