Devil Tumors
Radiolab
A man Robert, was obsessed with the Tasmanian Devil. Roberts hobby was to photograph these little "devils" as they devoured their meal. One day he was taking photos and he noticed something was wrong. The Tasmanian Devil's weren't them selfs. It turned out that the "devils" had a tumor. The weird thing was not just one Tasmanian Devil carried the disease. The whole species carried the tumor.
Wait What?
Christo Baars also noticed the strange lumps on the Tasmanian Devils. Dr Anne-Marie Pearse (a scientists) was pulled onto the case to figure out what was going on with the Tasmanian Devils. Anne- Marie found the answer...the lumps were contagious tumors, and they were leaping between Devils. Causing the whole species to have tumors.
