The artiodactyls are ungulate mammals with an even number of toes. This includes a wide array of familiar animals including pigs, cows, sheep, goats, hippos, camels, deer, giraffes, and antelopes.
The contrasting group, perissodactyls, are animals with an odd number of toes (and one middle toe bearing the weight), which includes horses, zebras, rhinoceroses, and tapirs.
mesonychids were the carnivorous-artiodactyls (i.e with hooves) that got replaced by true carnivores like cats (which have claws) today there are no carnivorous-artiodactyls only omnivorous-artiodactyls (pigs) and herbivorous-artiodactyls (hippos)
Whales and other cetacean mammals likely developed from artiodactyls (even-toed ungulates) which are represented on land by hippos and horses, not wolves.
There are hundreds of mammals, not just 5.
Prehistoric even-toed ungulates (or artiodactyls)
It is currently believed that the first Artiodactyls lived in the Early Eocene epoch 55 million years ago.

Of the same family. These even toed ( artiodactyls ) are of a ancient family of carnivorous mesonychids of the Eocene period. Of the cetacean ancestry by ear bone comparison.
Artiodactyls have an even number of toes protected by hooves. This would include horses, pigs, deer ect. Primates have five digits with opposable thumbs.
Even toed animals are Artiodactyla. The artiodactyls include animals such as cattle, goats, deer, sheep, antelope, camels, llama, pigs, hippos as well as numerous other groups.
