Well, way to go, Kevin, you big mean fat poopy-head. You just ruined it for everybody. :roll:
At what point do you stop saying the strain has been modified to a high degree and start saying a new strain has developed? Is a wolf the same thing as a dog?
Hm, it was my understanding that a new SPECIES has evolved when the two can no longer interbreed and create VIABLE offspring. The "viable" part has many facets, and the barrier can be mechanical (the reproductive organs don't fit), ...grrr...or a couple of other things including the offspring themselves are not capable of reproduction/are sterile.
I don't remember the specifics, but I can look them up. If anyone is REALLY motivated, I can go find my lecture notes on this. ;)
So wolves and dogs are reproductively viable and are both under the genus "Canis". If they were separated geographically or if a mutation made them no longer mechanically viable, then they'd be a new species. This process is called "speciation" and you can find a fairly simple explanation on Wiki.
As far as the whole "something out of nothing" approach, there are still several THEORIES out there floating around, including some very very good ones on how the planet formed and made all these neat layers. To be honest, I find it easier to believe something that can be physically demonstrated or proved instead of all the metaphysical explanations. After all, once upon a time, people thought that flies formed magically out of garbage... In any case, I have not read the whole thread, I've read...the beginning and the end, so if this was already covered, sorry. Agreed that we are not carnivores, that is easily evidenced by the structure of our jaws and observation of the larger primates. One evolutionary explanation for our ancestors gaining the ability to stand (while retaining opposible thumbs ;)) is the idea that we walked from the trees to the discarded kills to scavenge. It was a LONG time ago that I studied phys anth, but I was under the impression that the nutrition obtained by the acquisition of meat was accompanied by the massive expansion in brain size shown by the fossil record. XD Again, if anyone is ...really super motivated I can go find my notes or research it. If not, just some things to chew on...I should be (pre) studying for next term's Calc course, so I'll go back to that. XD
