Yes, we could, say scientists:
Humans may one day be able to regrow missing limbs, and even brain tissue.
At least that’s the claim of scientists who have mapped the genome of a salamander, the Iberian ribbed newt.
Many amphibians have regenerative abilities, but salamanders have the special ability to regrow whole organs, including parts of the brain.
Among the early findings in the salamander’s genome is a family of genes that can provide clues to this unique ability.
Scientists say this will one day allow humans to regrow limbs and could also be the breakthrough needed to cure Parkinson’s and other degenerative brain conditions.
