The fly is sverly challenging for us, because we have not been able to fullya re grown the limb. We're e how well they use the new the new tigit segment, the three growns. That at's sol part o the fun. And then we're still trying to think of a design, maybe a climbing design.
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.
