are tricolors a hybrid? if so what are they bred to just curious.

I could go on and on....continental drift, speciation from geographic isolation.... Check thread on 11/01/2005 Are Tri color hogs... Colchichine gave a good succinct answer.

Thanks for the recommendation! Here's the link

If there is a just God, how humanity would writhe in its attempt to justify its treatment of animals. - Isaac Asimov

Wouldn't this be classified as evolutionary convergence, where two or more species develop similar characteristics separately from each other, presumably for similar functions.

Example: whales and fishes - answer to moving in a dense fluid is streamlining. We all know that whales are more closely related to humans than fish.

chicken or the egg:

has the tri-color pattern evolved for harmless snakes to mimic venemous snakes, or venemous snakes to mimic harmless snakes?

also, when did the tri-color hog evolve, and why? how long has it been geographically isolated from its closest ancestor? who is its closest relative now? what function, if any, does its color pattern serve?

i think you have to answer at least MOST of those questions before convergence is an option.

i think that guy was talkin' 'bout the snout not color......the snouts look similar due to similar function???......

Convergent evolution or is it Parallel evolution? Who knows without genetic testing. I suspect it's the later due to the fact Heterodon and Lystrophis's similarities seem to be more than superficial and they appear to be more trait or genetically related. How far up the family tree is still up for debate. They were even classified in the same species Heterodon in the 19th century. Even without costly genetic testing, some one can test it out with their breeders by pairing up a western hognose to a tricolor hognose. If they produce F1 offspring that are fertile they are closely related and if they produce sterile offspring then they are distantly related.......
Sharks and Whales? How far back in the evolutionary tree of life do you want to go? All living organisms are related at one time or another if you believe in the scientific theory of evolution.
Dennis, falling asleep yet....snore, snore....or is it oink oink.

I meant to say Lystrophis was even classified in the same genus of Heterodon in the 19th century.
