Hey Dom. I'm sorry if I offended you somehow, but earlier in the post you sounded curious to what my findings might be. You were already on the right track, so I thought I would verify it with a DVM. I'm only trying to help the cause with education and the raising of awareness.

Well I read your article which just started more questions mainly on where is the pattern as to who has spikes and dew laps and who does not. An hour of surfing later (guess I will have to stay up late working on lab reports and ADES problems) and I don't see any pattern. I had no clue how large the “family” Iguanid is. Green Iguanas, Desert Iguanas, and Chuckwallas I knew of but it further includes basilisks, anoles, collared lizards and others I have never heard of too. The only general pattern I see is they are mainly new world, but there are also some on Madagascar. Within Iguanidae, with the exception of desert iguanas, they all appear to have some remnants of spikes and dew laps. But still within Iguanidae there is the wide swing in diet too. Now I am almost more confused than when I started, I hate that. Mark I mainly used Jen Swofford's site for the list and a search engine for photos. www.baskingspot.com/iguanas/iguanids/

Just all depends on where the igs evolved to in the different diets, looks and ability to survive in a particular region. We all should have a basic idea of how evolution works. Green igs being old world still have very basic, yet complex at the same time, body shape, form and function. Heck...they can't even walk and breath at the same time. It's entirely possible that the spikes have several functions. We know the dewlaps have several. A source of communication, change of size appearance, and for thermoregulation. I was just watching a show on Animal Planet last night that had two different types of giant ground sloth from the iceage period. Both came from the same stock, yet the ones that were in "Australia" were slow, gentle herbivores. The Harland's ground sloth in another part of the world are now believed to have taken in animal protein and may have even hunted. Same stalk...some split off into new worlds and had to adapt. The pattern I see is that each iguanid moved...adapted...and now we are left with the questions...

Hey Everyone-
No offense taken at all! I was simply trying to add to the discussion since I had already done some research and compiled what I found into the document. No sense in re-iterating it all.
Joe- I WAS anxious to hear what the Prof had to say. The one thing I couldn't put my finger on (and it looks like MAR wasn't able to either) was the eveolutionary aspect of the spike development.
MAR- Welcome to my world Bud. I had a heck of a time trying to uncover anything substantial in the scientific world. Not many scientists write about Iguanas!
Anyway, I look forward to more discussions on this.

Heck Dom I have been in your world for months. Being an engineering student I read technical papers, reference (this includes text) books, and data sheets many times a day. Even being in a field that has a few hundred years behind it and thousands of people working on it I still have troubles finding info that I need.
Remember igs have only been popular in the pet trade for (almost) 20 years. Even 10 years ago very little was known and still less readily available.
And yes Joseph we will never know even 2/3 of what we should to keep igs as pets.
Mark
