Boar

Boars were a type of pig (PROSE: Mad Dogs and Englishmen) often caught for food on Earth. When she first met the Fifth Doctor and Peri Brown in Egypt in 1400 BC, Erimem invited them to sample some freshly-caught roast boar. As Peri was a vegetarian, she baulked at the thought of eating the boar. The Doctor advised her to pretend to have eaten it by moving it around her plate. (AUDIO: The Eye of the Scorpion)

Nyssa was chased by a boar, specifically a Mummerset black, in Stockbridge in 1199. (AUDIO: Castle of Fear) A boar who had been killed by a Krynoid-possessed wolf was found by Henri d'Arrée and Moses of Tyre when they looked through an English forest for their lost horses in the 12th century. (AUDIO: The Green Man)

Boars had become extinct in England, but they were reintroduced in 1987. This occurred during a massive storm in Kent, when a farm that raised continental boars was damaged and the boars escaped. According to the Eighth Doctor, some of these boars came nextdoor to the Doctor's house, and he taught them to talk. They evolved into the intelligent Tusken race. Brewster was a sentient boar who managed a 21st century hotel on an asteroid; he said the Doctor's account of the repopulation was heresy, since he believed it was due to divine intervention.

Boars were listed in the Avalonian Bestiary of all animal life on the Earth colony Avalon. (PROSE: The Sorcerer's Apprentice)
