vastigi
Vastigi is a term that can refer to several different concepts, primarily in the realm of biology and genetics. In its most common usage, vastigi is a colloquial or informal term sometimes used to describe vestigial structures in organisms. Vestigial structures are anatomical features that have lost their original function through evolution. Examples include the human appendix or the pelvic bones of whales. These structures may be reduced in size or appearance compared to their functional counterparts in ancestral species.
The term vastigi might also be encountered in specific research contexts, potentially as a less common synonym
