They didn't "evolve" like you may think, they were "artificially selected" by humans from the truly wild cattle known as the Aurochs and the Celtic Longhorns.
No, they evolved from humans,bears,cows and monkeys!
Tempting as the thought might be - no. Humans didn't come from cows-as-we-know-them. But cows and humans are both vertebrates and placental mammals, so way back when there is a common ancestor. A fairly small mammal that branched off time after time- One line eventually turning out cows and another eventually turning out humans.
They evolved from even toed ungulates, or animals with even hoofs like cows and giraffes.
Angus cows are beef cows, not dairy cows. Holsteins are dairy cows, not beef cows, which is where we get the majority of our milk from.
COWS COWS COWS they eat cows.
No, though cows and whales come from a common ancestor being the Pakicetus. Cows are "sisters" to hippos, and both of these species are "cousins" to whales. Cows, like all other ungulates, have their evolution much farther back on the evolutionary tree than whales do. Whales came from mammals that went from being terrestrial to oceanic in a matter of 8 million years. See the related link below for more info.
"Moo cows" are, essentially, cows that moo.
