No rush to trouble. I'm a nice lagmonster, really.
(wheat) Is nearly all produced artificially nowadays. The majority of wheat plants are heterozygous and contain some rather dangerous genes. It's a whole Evil-Corporation-screwing -the-poror farmer thing. Many commercial famrers need to buy a new seed crop each year.
To be honest, I will have to take your word for it. My father was the farmer, not me. Nonetheless, I know you probably know what you're talking about and I don't have any reason to doubt it.
At that, I was being verbally berated by my wife when I called her to ask, because I of all people should have known better: Of course there is the high-yield and genetically resistant seed for sale as opposed to the grass-variety! Still, I don't agree with labelling wheat in general as something that is dependant on humans for its continued existance! I know that wheat has been cultivated by humans over a very long time, but it can be grown in a field on the whims of nature (there are, I believe, painfully hippy 'organic farmers' who do this, though what they produce is often little better than grass).
Tell you what: Let me come back to this. When I go in I will check the CFIA and AgCan net for links to sites that will help (there's a cereals website somewhere in there), and see what I can learn.
(There are still wild chickens in Asia...)not of the same species as the domestic chicken
Gallus Domesticus probably originated from one of several jungle fowl in Southeast Asia...and I'm at least 50% sure that it still runs wild there. Since I don't have confirmation in front of me, I'll leave it alone rather than press it without a clue.
But those wild cats are still living off human debris - they're hunting commensals, they're protected by 'aw ain't they cute'-ness that keeps all competitors at bay etc etc
You're good. Within cities, you're right - strays are almost always former pets or runaways. Nonetheless, when you get out into the country, there are families of common house cats who have endured for generations out on their own. And what protects them from the farmers is primarily the fact that they prey on the things that prey on the crop. I understand, after looking at it, that you're right about being intertwined with humans, but do you believe that they would qualify as surviving on an artificial system? They certainly thrive on it, and they reap its benefits, but would they become so much worm food if, say, all the farmers up and left?
No, now you're creating an artificial barrier between artificial and natural selection. Selection is selection is selection. Bos taurus is a massively successful species, and it doesn't matter if the enivronment that shaped it heavily factored another species (us), because they've exploited us for their own evolutionary gain as much as we've exploited them for a hamburger.
You're right that they need us, however they got there. Although we could start a whole new thread arguing over whether they're a successful species. I suppose I was looking for a stronger argument in the form of some organism that wasn't already an artificial thing itself, but that's silly.
No, rats were a poor example, but I meant commensals in general. I'm no expert on the taxonomy of commensal rodentia, but I'd bet my Manhattan heels that there are species of rat and/or mouse that rely completely on human enivronments (tube mice, anyone?)
Not a clue, so we'll call it dead even and go for a beer.
