The idea of humans re-growing lost limbs actually gave me an excellent idea for a series of written works.
Imagine in the far future humans have the capability to fully transplant someone's entire brain construct into a new body. Weirdly enough, the body is the recipient and the brain system component is the donor. thing. This would be such a time in the future where 90% of the complications involving nerve connection/re-connection limitations and other complications have been solved and streamlined. Medical science is so advanced that we could even do this with a mechanical chassis and someone could live as a cyborg, mostly machine, but the human component is what drives the ship.
So many questions to answer. How long can one's brain age even if the body is ready to die Could old work with the new Since hormones primarily affect bodily changes, does that mean a brain from one gender would simply work under the conditions of the other gendered body whilst subjective to the hormonal wirework of that new body Will the former David now be able to give birth
We have to keep in mind so many things about genetics that from a network of on/off signals to even developmental deprivation (on purpose, a future where humans could reattain a lost physical capability seems so far-fetched and impossible. So much so that any attempt to advance it will only develop and uncover a plethora of problems not originally foreseen.
This isn't like the movie Robocop.

I see 2 core reasons for humans not being able to regrow limbs:
1) it would have an enormous life force cost that would cripple the lifespan
2) human mind and society would just not be the same if injuries were neither fatal nor permanent
In summary if the human could, it would not be human

If a salamander has non-uniform coloration on its skin (such as, in this example, a pattern of spots, and it loses a limb, and the limb is preserved in a freezer, will the limb that regrows to replace the severed limb have the same pattern of spots as the severed limb had

We having those regrow limbs genes in our dna. But it be disable some where in the path of evol. We can reactive it but will need process though many generation for it to catch up and perfect. Just image what happen if bone grow faster than skin or muscle and it will happen.

Regrowing or regenerating body parts get very dark and distopian very quickly, till what extent should we do it, can we regenerate brain, a person's clone, a dinosaur arm. I can already imagine some mad scientist mutating into that lizard from spiderman lol.

I think the same way as yuval noah harari ideology, especially the future where people could grasp those regenerative abilities, alas, they choose to commercialize the products, and upgrade the wealthy instead of heal the wound

That’s the next thing because if ppl that lose limbs experience a phantom limb. Maybe the brain doesn’t even fully register that the limb is gone. So why would it try to regenerate something that is still there

I hope we figure out how to regrow limbs soon I wish we would invest more in stem cell research especially now that we know it can come from bone As someone with cerebral palsy it would be very helpful

If we learn this technique with the blessing of the Lord, we may cure cancer, body parts, hearts, and lives as well; literally, humans become immortal by this or semi-immortal like this.

But there should be enhanced emphasis on getting this done. Maybe take away from less important projects because this would pave the way for mankind’s ultimate goal- immortality.

SALAMANDER: We will not tell our secret. We've seen what happens if you have our regenerative ability
SCIENTIST: You've watched the Hulk and Deadpool movies, huh

So is this related to why after accidentally cutting my fingers when chopping food before, with the cuts being really deep, I can’t seem to find a scar after healing

Can these stem cells deplete. Like if the salamander regenerate for like a many number of time will it lose its regenerative abilities, does their have their limit

Hi Ted ed
Awesome video.
This topic recently I dreamed of and asked question myself.
What a coincidence, you posted video.
Thanks for answering.

I would love full regeneration.
But it would probably cost to much energy and increase the risk of cancer, since modern humans have a very unstable genome.

The short answer as to why axolotls can regrow limbs, but humans can't: it's a lot easier to rebuild a shed than it is to rebuild the Taj Mahal.

I see, Spider-man writers got Curt Connors totally wrong. He was researching the wrong animal and should turn into the Salamander, not the Lizard!

Sacoglossan sea slugs go even further they can detach their heads and regrow their entire bodies! (search SciShow leaf sheep for more info)

Axolotls also don't age, even though they die. If we can alter our DNA to regrow our limbs, we'd probably never age too till we die

Spiny mice do that too Seems like they should study them the most for possible human applications. Exciting time to be alive! Go crispr!
