. Boa constrictor snakes have tiny pelvic girdles and leg bones within their bodies. Since these structures are not functional,
blondinia [14]

Those organic structures that do not seem to play any important biological function in the organism that possesses them are known as vestigial structures.

<h2>What is a vestigial structure?</h2>

A vestigial structure is one that has atrophied or lost its original function throughout the course of evolution.

  • It generally refers to those organic structures that were useful at some point, but are now practically or totally useless.

  • These structures are preserved as an inheritance of the evolutionary process, because at some point an ancestor of the current species had that structure, which was functional, but it ceased to be important and would end up atrophy.

Therefore, we can conclude that vestigial structures are structures that some organisms still conserve as an inheritance from their ancestors but that, for some reason or another, are no longer useful for the functioning of the same.
