Answer:The discovery of the "distal-less," or Dll, gene in many different phyla.
Explanation: Appendages of animals are any external attachment or extension of one or two body parts of an organism in order for it to be able to effectively perform its responsibilities.
The morphological and functional changes or evolution of appendages is responsible for the adaptive radiation of tetrapods, arthropods and winged insects. Recent studies tends to show that all animal appendages may be homologous through the discovery of the "distal-less," or Dll, gene in many different phyla.

A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism. Plants also exhibit phototropism, or growing toward a light source. This response is controlled by a plant growth hormone called auxin.
