Boar

Boars were 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)

Boars had become extinct in England, but were later reintroduced in 1987. This occurred during a massive storm in Kent, when a farm that raised boars was damaged and the boars were allowed to escape. Some of these boars came to the Doctor's house. They evolved into the intelligent Boar race. Brewster was a sentient boar who managed a 21st century hotel on an asteroid.

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