Episode notes

Is it generally true that younger organisms are better at regenerating, or things like regenerating, than older ones are? Exact? So sas lik, i study sos like so i think, i think you brought up different points. The animals that can regenerate don't all come from evolutionarily close lineages. They're all scattered across the animal philogony. It does surprise m that again, i mean, we all these animals can heal when they get a wound, right?

Biological organisms are pretty good at healing themselves, but their abilities fall short in crucial ways. Planaria can be cut into pieces, and each piece will regrow into an entire organism; but for most advanced animals, loss of a limb becomes a permanent condition. But why should that necessarily be so, if an organism’s genome knows what it’s supposed to look like? Lea Goentoro’s lab has recently produced surprising results that indicate that it’s easier than you might think to coax animals into regenerating limbs.
