In august 2006, a world sensation was born in Copenhagen Zoo. Three young babirusa/pig hybrids. These may have changed genetic research as we know it, since sientist did not believe that two such different species could breed. One of the piglets is babirusa coloured, one is a mix of pale and grey, and the last one is just pale.
This is a photo of two of the piglets. As you can see, this is the pale one, and you can see the back of the babirusa coloured one.
