Others do not understand the full nature of evolution. 20 years ago, I had seen a new vision of evolution in a few textbooks that evidently hasn't made wide enough circles. It is that evolution is not radially adaptive. That means, we don't evolve something because we need it. It means that some mutations survive, some don't. For example, we have an appendix that we don't use or need. But there hasn't been enough humans born without one that survived as well or better than we have to take over species procreation, so it is still there. Evolution is not perfect and it does not have a guiding force or plan behind it. It's a fancy way of saying "crap happens."
Okay, I completely understand this.
I own one of the text books that explain the new ideas of evolution; it's the third edition of
Animal Diversity. Adaptive radiation, is, however very much a part of evolution (Darwins Finches). Adaptive radiation is not when an animal selects its niche, but rather when one species mutates several variations better fit to survive several niches.
I did not say evolution chooses its own path... though. I basically stated that an animal species will not survive on a diet that makes them unhealthy. The same goes for the hip displaysia example... yes, they could survive and breed, but a whole line of hip displaysia ridden wolves would be outcompeted by healthy wolves and would not survive. That's the whole idea of natural selection. Beneficial mutations persist (we hope [

]) while non-beneficial mutations cease to persist.
I tried to post this morning about the domestic vs wild wolves life span, I'm not going to go into the details I wrote earlier, though. You can't base that argument soley on diet. Wild wolves face way more things than diet than can and will affect their lifespan. The comparison is flawed, at best.
As for the research... a good scientist (whether or not you have a degree is irrelevant) will present all of his or her findings happily. I shouldn't have to go asking for them. My point of view is critical; I won't take what he/she says as fact without proof. If I do decide to go raw... there is plenty of documentation. I am one of those who considers dogs and wolves of the same specie; there for, a study on the natural diet of wolves will do for me.
Anyway, that's my peace. I'm getting too worked up 'cause I keep getting words put in my mouth (I.E. the health of the animal was not so as directly linked to evolution in my post as it was made out to be by another poster), so I'm going to back up take a deep breath, and move on.
Oh and I would like to mention as I was reading I got scared it was soon to become a religion war, but was pleased to see that nothing more was said of that, this is about raw food right
)
lol, I seriously thought about it, but that is a debate best left alone (as it's too personal). I will say, though, I am a Christian who happens to believe in evolution.
