Au contraire mon ami.
I'll back off of the camel analogy. I thought about it over the holiday,
and realized that the fatty portion of a camel is not supported by
As far as pigs are concerned, modern farm-style pigs have average sized
neural spines, but consider wild members of the group. The warthog (as
well as it's larger/extinct cousins) has rather long neural spines, which
serve as anchors for the neck muscles (useful for rooting for food). Bison
have long neural spines to help support the heavy head. It is possible
that animals evolve long neural spines for the same reason ceratopians
elongated the frill, more muscle attachment gives a stronger structure
(see, it does relate to dinos). ;^)
