Regrowing limbs not so science-fiction after salamander-like discovery – Siliconrepublic.com

The discovery of the cartilage repair system was unexpected in that it is discovered to be more efficient in ankle joints, however less so in hips. After scans with sensitive mass spectrometers, the team discovered that cartilage in ankles is young, middle-aged in the knee, and old in the hips. Their presence in humans, the team said, is down to an evolutionary artefact that remains on in us through joint tissue repair.
