There's a common argument that I've always found interesting: that the Torah names ten species of kosher land animals, and that no other animals have ever been discovered to display the two signs of a kosher species. (The signs are that the animal chews its cud and has a split hoof.) Also impressive is that the four animals identified as showing only one of the two signs (aka, be warned!) remain the only species to date that only show one sign.
The animals listed in Deuteronomy (Devarim) are the ox, sheep, goat, deer, gazelle, yahmur, the'o, pygarg, antelope, camelopardalis.
My question: Where is the cow? From everything I can find, the untranslated animals above are clearly not cow-like. And cows don't seem very ox-like to me.
More fundamentally: Is the basic claim true?
