The dna of humans and mice is almost 92% Similar. This similarity indicates that. Nice have a tail, while humans have a tailbone. The tailbone is a structure

Answer

The tailbone is a homologous structure

Explanation

A homologous structure is an organ/bone which is present in different animals (like in humans and the mice) that has common anatomic characteristics which shows that the organisms had a common ancestor. In this case, the organ can relate in functionality or formation.

The tailbone is a homologous structure.

Homologous structures is a bone (or organ, but in this case, bone) that shows up in different animals in different animals (mice and human). It shows evidence of evolution by highlighting different similarities in different organisms that show that they may have descended from a common ancestor. It may have a very similar form or function in the different animals.
