Fun Fact
“Vestigial” comes from the Latin word vestigium, meaning “footprint” or “trace.” Initially referring to physical remnants, it evolved to describe anything lingering or diminished. In evolutionary biology, it describes traits like the human tailbone or appendix, which no longer serve their original purpose but offer fascinating insights into our species’ history.
