Why don't humans regrow lost limbs?

The discussion centers on the possibility of humans regrowing limbs, inspired by the regenerative abilities of certain animals like newts and salamanders. Participants express skepticism about the feasibility of such regeneration in humans due to the complexities of embryonic development and the differences in gene expression between embryos and adults. While some believe that advancements in gene therapy or regenerative medicine could eventually lead to limb regrowth, others argue that developing advanced prosthetics may be a more practical and cost-effective solution. The conversation also touches on ethical dilemmas that could arise from enhanced prosthetic technology, suggesting a future where cybernetic enhancements may become preferable to biological regeneration. Overall, the potential for limb regeneration remains a speculative yet intriguing topic in the realm of biology and technology.

So, nowadays, lost limbs can be reconstructed without any genomics and stem cells.

Remember, we are not talking about reconstructing something that LOOKS like a limb, we are talking about reconstructing something that SERVES as a limb.

If you reconstruct bones, and muscles, and blood vessels, and nerves, and joints, and skin,
then your item LOOKING like a limb will SERVE as a limb.

Do you have any evidence to support a claim that it is currently possible?

No, I have not. But I am looking for the opportunity to prove that it is possible in a way I have described in rough details!

I believe that it is possible and with time will be done as the progress that Mankind is making is exponential and the fact that it already happens in other animals even though they are quite different from us proves that amazing regeneration is possible.

(there seems to be a problem as my last post seems to disappear unless I send another after it!)
