Origin of 'vestigial'
The word 'vestigial' originated in the mid-19th century from the Latin word 'vestigium', meaning 'footprint' or 'trace'. It was first used in the context of biology to describe structures in organisms that have become reduced or functionless over evolutionary time. The concept of vestigial structures played a significant role in the development of evolutionary theory, as it provided evidence for the idea of common ancestry among different species.
