What animal did cows come from?

Cows originally come from an extinct and/or lost city on a deserted island formerly called by some historians "Akowlantis". ** It's said to have neighbored the current countries of Fiji and Poland. The cows came to Europe by riding on the backs of pignoritiniums, otherwise known as FLYING PIGS. Once the country became extinct, the cows survived but the pignoritiniums, unfortunately, died from a meteorite. This is where the term "When Pigs Fly" comes from. Their cousin, the common pig, survived due to their ability to adapt to any terrain. This is why pigs now bathe in mud. Will the flying pigs ever return? That's another question to ask Wikianswers.

**footnote: These facts are only accepted by a handful of historians. Big Brown, Dr. Pye and Scanny (code names, of course) are the only living historians left from that group.
