Question

question 15 of 25 which is most likely an example of a vestigial structure? a. tailbone of a human b. tail of a monkey c. flower of a plant d. fin of a fish

Explanation:

Vestigial structures are remnants of organs or structures that had a function in an ancestor but are no longer useful or have reduced function in the current - day organism. The human tailbone (coccyx) is a vestigial structure as it is a remnant of a tail that our primate ancestors once had. Monkeys use their tails for balance and grasping, plants use flowers for reproduction, and fish use fins for swimming, so these are not vestigial.

Answer:

A. Tailbone of a human
