I think it's worthwhile in that it explores questions people have about "what if." We all have more information now, instead of just being told "They are not hybrids because Don and KJ and Graham say so." Now we know the arguments and the rebuttals, and have more to base our opinions on.

Umm... Don't you mean that YOU, Kjun and Don haven't identified any "throwbacks" from these breedings? What kind of throw backs would you look for? Maybe a normal with an aberrant head pattern?
Here's an interesting little tidbit. The more crosses in a snake the less frequent, the throwback. (Or maybe they just become harder to Id as "throwbacks") So if you cross a Creamsicle, to a Beast, and then That offspring to a Cornduran, Then those to a Frosted Ultramel, What are you going to look for, as a throwback, again?
Any ideas? So ah what do you look for in a Corn that's 6% or less European Rat?

Are they hybrids too? No, it's a genetic mutation!

That would be three generations, not one. And that is not evolution, that is survival of the fittest. SOTF drives evolution, but itself is not evolution.

You do know that garter snakes give live birth dont you? If tesseras were a hybrid with some species of garter snake, that piece of information alone would be worth far more than many many tesseras.

abell, still waiting for you to identify some hybrid markers (obvious or cryptic) that you have personally identified in nontessera siblings.

Actually that would be 2......And SOTF doesn't change the look of a entire species in 2 generations. As I assume your not a scientist, and scientists call it an evolutionary jump. Then to me it's evolution.

I'm dutch so, sorry if I get the english names mixed up. But condescending is also not necessary.
FYI; I always find it funny when people start to be condescending while the other person is in no way rude. Always tells a lot about a person's character.

So you did or didn't know garter snakes give live birth?

again patronizing me. Yes I did know Thamnophis gives live birth. Just not my kind of snake. Plus again I'm Dutch and don't always get the English names straight.
But then again one could be nicer to somebody

You implied that teserra was a hybrid a garter snake, I was just trying to get some clarification.

BTW Mike, evolution normally takes thousands of generations. Not 1, 2 or 3.
SOTF is NOT a scientific description, it's also incomplete and a misleading term. It doesn't convey the complexity of natural selection.
So SOTF is only a SMALL portion that drives evolution there is way way way more that comes into play.

Read my post again and you will find I said no such thing. I said that some people seem to believe genetic mutation is far more unlikely then it being a hybrid with another species just for the pattern. And then taking the time, money and determination to produce a cornsnake with that pattern. Sorry but that sound pretty unbelievable. Especially when that goal is finally reached the animals are then sold on as normal motley/striped corns at low costs.
Now what is more likely, a genetic mutation which happens every day and is as normal as the earth revolving around the sun.
Or the hybrid theory?
