This is an example of vestigial structure.

Vestigial structures are structures (cells, tissues and organs) found in an organism that has lost most or all of its primitive function through evolution. The vestigial structure has performed vital functions in the organism in the past but as there are changes in species as a result of natural selection, the structure became less important until it no longer functions. A reduced nonfunctional digit on the paws of dogs known as a dewclaw is an example of vestigial structure.

The reduced nonfunctional digit on the dog's paws known as a dewclaw is an example of VESTIGIAL structures. These structures were present in a dog's ancestor.

Vestigial structures and evolution

Vestigial structures are structures that lost their functionality over the course of evolution.

  • Vestigial structures are present in the target taxonomic groups (in this case, dogs) and a recent ancestor where this structure had a determined function.

  • Examples of vestigial structures include the human appendix or are the loss of wings in island-dwelling birds.

In conclusion, the reduced nonfunctional digit on the dog's paws known as a dewclaw is an example of VESTIGIAL structures. These structures were present in a dog's ancestor.
