Well, obviously you can’t regrow your head and brain, but Planarian flatworms can… and the discovery of the gene that (probably) makes this possible has the media doing their customary pulp-sf extrapolation thing and suggesting (albeit sarcastically in the case of El Reg) that we’ll soon be able to grow ourselves a new bonce By Using Science [via SlashDot].
It has a certain Frankensteinian charm, I’ll admit… but surely it’d be marginally more useful to discover a gene that could regrow the rest of the body from the neck downwards? Or am I just falling into the trap of assuming that the nexus of consciousness (and hence personhood) is located between the ears?
