Explicación
## Step 1Vestigial 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.## Step 2Dolphin 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.## Step 3The 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.## Step 4Cat legs are not vestigial structures. They are fully functional and are used for movement and other activities.## Step 5The limbs of animals are not vestigial structures in general. They are essential for movement and other functions, depending on the species.## Step 6Wisdom teeth are considered vestigial structures. They are remnants of the teeth that our ancestors used to grind plant material. In modern humans, they often cause pain and problems and are sometimes removed.
