Hedgehogs are a small, insectivorous (insect eating) mammal that can be found throughout the world. They are native to England, Europe, Africa and Asia.

In the 1970s, a gene related to how our brain grows our limbs was given the name âhedgehogâ in relation to the spiky appearance of fruit flies with a defective version of the gene.In 1995, three strains of the âhedgehogâ gene were found and named âDesert-Hedgehogâ, âIndian-Hedgehogâ, and amusingly, âSonic-Hedgehogâ.onic Hedgehog Homolog (SHH) is one of three proteins in the mammalian hedgehog family, the others being desert hedgehog (DHH) and Indian hedgehog (IHH). SHH is the best studied ligand of the hedgehog signaling pathway.
