Tom, your post was VERY in depth, and detailed in trying to explain some of this, you did a good job of showing that this indeed is a real mystery. It does seem that the genetics of these Pines(and maybe other Pits.)might very well go beyond anyone's understanding thus far. After all, you have been dedicated to the Pit. genus for some time, and have been diligently researching into this for a long while now, and STILL come up short with any real answers to this genetic puzzle.
I wish I had been into Pits like I have been into so many other species/ssp. of snakes over the last 41 years, then I might have a little more insight on this. But since I do have a VERY extensive knowledge into many other types, I can definitely see here from just those few exchanges we have had about this, that this is an extremely complex issue, to say the least.
Before this post, I thought I might have seen some possible answers(and still might), but as I found out more and more on this, I actually noticed me KNOWING probably less and less!..LOL!
I'm beginning to get a pretty good "picture" of the frustration you've been running into with this.
I'm not sure at all what to make of it, I guess that makes two of us, huh???
I will say however, those animals you posted were really superb looking, and unique. I hope you can find your way to getting some legitimate answers about this sometime soon.
Until then,.........the mystery continues, as does the investigation...LOL!
thanks again for those great posts Tom!
