There are at least eleven different species intermediate between artiodactyls and cetaceans in the fossil record and they occur in precisely the right sequence expected if cetaceans are derived from artiodactyl ancestors.
It has a nice figure of artiodactyl phylogeny, including cetaceans.
In view of the divergent anatomy of babirusas, most artiodactyl specialists agree that they represent an ancient lineage, Babyrousinae, which branched off from the rest of Suidae early in its evolution (Thenius 1970).
A few artiodactyl specialists make a point of using the latter name, but the former is more widely used and would easily win in a fight.
In more recent publications however (Groves 2001, Meijaard & Groves 2002a, b), it has been argued that most of the supposed subspecies are distinct enough to be recognised as distinct species, being as different from one another as are universally recognised species among other artiodactyl groups.
The artiodactyl in the photo is a charismatic and very friendly male Babirusa.

The proximal parts of their limbs were way more stocky that is usual for an artiodactyl, giving them an almost bear-like shape.
Mostly it comes down to a superficial similarity between certain Cenozoic artiodactyls (like cainotheres) and lagomorphs, and the transverse chewing style and artiodactyl-like ankle structure of lagomorphs.
