The Thread of Science

Nope. They actually do have organs. But not the main organs such as brain and heart because they are too simple organisms to have them. Also, their body movements only consist of moving their tentacles.

wow.

Interesting reading, this "Jellyfish". By the way, have you seen this?

The species (yes, there is only one species that does this) in question is called Turritopsis dohrnii. Let me first explain the life cycle of the jellyfish. They are "born" as eggs. The eggs attach to something, and grow into polyps. They look like tiny plants, but aren't. Then they distach from the structure and become jellyfish, when they mate. (They are asexual as polyps.) The actual process of regeneration actually entails the jellyfish to turn from a jellyfish back to a polyp.

Let's translate this to people. After mating, the humans would give birth and then shrink back to become toddlers themselves. Imagine a world like this. Of course, no one plans to have the age-reversal forced upon them, and they would certainly not want it to bring them back to childhood.

Could this work? One thing I didn't mention: the jellyfish appears to die before becoming a polyp. That's right, this could almost be called death and rebirth played out physically! (Tell that to your local pastor.) But seriously, this is not a scheme that just makes you younger, it just kills you and rejuvenates some of you to live again.

Btw where do you guys get your science news?
