Axolotls and cnidarians expand the question, not the promise
Comparative primary research. A 2022 axolotl study used single-cell genomic profiling to characterize populations in the telencephalon during ordinary maintenance and regeneration. This provides a resource for examining brain organization and regenerative responses in a salamander. It does not show that the same response can be transferred directly into an adult human brain or applied after the loss of a person’s neural information.

A separate 2022 comparison of Turritopsis cnidarians investigated genomic and transcriptional features associated with life-cycle reversal. The work is relevant to questions about rejuvenation in those organisms. Biological immortality in this context should not be read as invulnerability to every cause of death, or as evidence that a human individual can be reconstructed after destruction.
The proposed comparative program begins with mechanisms and constraints: what phenomenon occurs, in which organism, in which context, and what would have to be shown before a useful comparison could be made? Rangers locate the literature and its differences. Wizards determine whether the comparison is scientifically informative. Druids keep the organism’s actual biology from disappearing into an attractive analogy.
The mythology gains something from this discipline. Lichen contains forms of life with very different ways of developing, maintaining themselves, and responding to damage. Respecting that variety is more interesting than making every species a less advanced version of a human. The research question becomes what can be learned from differences without pretending those differences have vanished.
