Tales of Trolls go back centuries. The size and shape of the particular beast varies from country to country, but generally they are of a roughly human form, greater than average size (mostly giants,) and posses a below average intelligence. In the more fantastic tales they may have animal features - tusks, horns, trunks, multiple eyes, etc, as well as magical powers and weaknesses. In Sweedish folktales, direct sunlight will turn trolls into stone.
I imagine them as a degenerate offshoot of humanity, split off from our neolithic ancestors, afflicted with chronic genetic disorders, devolved into near-beasts from centuries of inbreeding. This would also explain the many folk-tales of trolls stealing human babies in order to bolster their number.
