The ability of an organism to regrow a lost tail, such as in many lizards, is often achieved through a process called:
Show answer and explanation
Correct answer: Autotomy followed by regeneration
Autotomy is the voluntary shedding of a body part, typically to escape a predator. After autotomy, specialized tissues at the stump initiate a regenerative program; however, the regrown lizard tail typically contains cartilage rather than true vertebrae.
