Modifying lab mice to grow wings through DNA editing is also challenging for many of the same reasons that make it difficult for humans. The biological process of growing wings involves not just the genetic material but also complex physiological and developmental processes, and it is not clear that these could be mimicked or modified through DNA editing alone.

Additionally, even in mice, there would likely be safety concerns with any new or altered anatomy, such as the structural integrity of the wings and how they would interact with the rest of the mouse's body. Moreover, there would also be ethical considerations, such as the well-being of the mice themselves and the potential for their use in testing or other activities.
