		Cetartiodactyla is the superorder to which whales (including dolphins) and even-toed ungulates have currently been placed.
		The term Cetartiodactyla is most commonly used to describe the classification that whales evolved from within the artiodactyls.
		Alternatively, the term Cetartiodactyla is used to denote a clade where Cetacea and Artiodactyla are sister groups, but where Cetacea did not actually evolve from within the Artiodactyla.

		The two ungulate orders (Perissodactyla and Cetartiodactyla) do not isolate from the rest of the mammals together, and thus they do not form a distinct taxonomic group.
		The easiest way to distinguish the two types of ungulates is to look at their feet (and hooves): Perissodactyls (generally) have an odd number of toes on each foot, while "artiodactyls" (the ungulates within Cetartiodactyla) usually possess an even number of toes on each foot.
		Despite the even-odd differentiation, there are exceptions to the rule: for instance, both tapirs (Perissodactyla: Tapiridae) and some peccaries (Cetartiodactyla: Tayassuidae) have four toes (and hooves) on their front feet, and three on the rear.

		Re: Cetartiodactyla (was Re: Cladistic taxonomy (was Dietary factors))
		I recognize a separate Order Mesonychiformes, so no matter how it and artiodactyls and cetaceans are interrelated, I will be able to reflect it in my classifications without having to change the contents of any of these three orders.

		Cetartiodactyla is a superorder proposed to denote a clade including the orders Cetacea and Artiodactyla.
		Alternatively, Cetartiodactyla may refer to a classification in which the Cetacea actually evolved from within the Artiodactyla.
		The term Cetartiodactyla was created by merging the names of the two orders, Cetacea and Artiodactyla, into a single word.

	ADW: Cetartiodactyla: Information
		Cetartiodactyla is a group comprised of two orders of mammals that are superficially quite different and that, until recently, were recognized as two separate monophyletic clades.
		Recent molecular evidence suggests that Cetacea evolved from artiodactyl ancestors.
		Experts suggest the monophyletic clade representing artiodactyls and cetaceans be called Cetartiodactyla.

	Cetartiodactyla - Even-toed ungulates (and whales)
		To accommodate the merging of these order, a hybridized name "Cetartiodactyla" has been created.
		Like the hybridized name Cetartiodactyla, the close allying of the hippopotamuses and cetaceans has created the need for a new suborder:
		The evolutionary history of "artiodactyls" (the ungulate members of the Cetartiodactyla) is relatively well known, since, due to their large bones, fossils are plentiful.
