## Step 1<br />Vestigial structures are parts of an organism that are reduced from a previous ancestral form and are usually nonfunctional in a descendant. They are remnants of features that served important functions in the organism's ancestors.<br /><br />## Step 2<br />Dolphin flippers are considered vestigial structures. They are remnants of the limbs of terrestrial ancestors of dolphins. Over time, as dolphins adapted to life in the water, their limbs evolved into flippers, which are used for swimming and maneuvering in the water.<br /><br />## Step 3<br />The wings of an ostrich are also vestigial structures. Ostriches are flightless birds, and their wings have evolved into limbs used for running and other activities on the ground.<br /><br />## Step 4<br />Cat legs are not vestigial structures.
