Immortality has always been a term that humans were interested in. From inventing religions to live forever in heaven to searching through space to find some weird anomalies. But as it turns out the answer for immortality might be closer. In the early 90s scientists discovered that turritopsis dohrnii a really small type of jellyfish which originated from Mediterranean Sea but now can be found in all around the world’s tropical waters can be immortal. This animal can reverse its life cycle when it comes to end. Its cells are getting younger and it is changing into polyp the earliest stage of jellyfish’s development. It isn’t said that some turritopsis dohrnii will live forever but it is possible if nothings eats it or other unpredictable conditions happen. But who knows maybe the research on this jellyfish will show scientists how to make humans immortal.
