You know it's rather interesting how the SHH gene got its name. Scientists were calling any gene, that had a mutation that caused a cell to be spiky, a hedgehog gene. Then they looked to see if that gene were important. They went through all the names of real hedgehogs, and none were really that essential. They had run out of natural names when they found another hedgehog gene, so the called it Sonic, the Sonic HedgeHog gene, or SHH. Its gene product turned out to be a vital signal in embryonic growth and development.
