Well, we did home brains, just not as complex as we have now. We could build simple tools, but not build an internet.
This has nothing to do with how developed our brains are, or at least that's a really bad example. The reason we can build the Internet now and not thousands of years ago is because we have those thousands of years of progress to build upon. I doubt that humans in the earliest civilizations were significantly less "smart" than we are now. Of course, if we're talking about the origin of Homo Sapiens itself, that's another matter.
And yes, our brain to body ratio is outragouse for a herbivore, and if a vegitarian was caught in a survival situation, the only way they could survive while keeping there vegginess, would be to cook every last meal they ate.
I don't really think most vegetarians would be against eating meat if they seriously were in a situation where they needed to do so or would die. Just saying.
Outsmarting and running down tasty animals is the reason humans aren't cattle. Leaves don't run away from you, or try to hide. All you need to "hunt" leaves is enough brain cells and optical tissue to notice that "that thing's green, eat? EAT!" and plod over to it.
This is a very piss-poor assessment. A
lot of human reasoning, intelligence, and memory has always gone into figuring out what is and isn't edible, both in terms of animals and plants. It takes curiosity and intelligence to figure out what's edible and what's poisonous in a new setting, and to pass that information down to your children, and so forth. It's not just a matter of "GREEN? EAT!". If you do it that way, you'll either not get enough nutrition (because you're too stupid to break open nuts or dig up tubers/roots, and so forth) or, more likely, die (because you're too stupid to not poison yourself to death).
One of the reasons humans have been able to spread to so many places has been our ability to figure out how to produce food out of strange things, which strange things are edible, and which parts you can eat without dying. This applies to both animals and plants (although with animals it's
usually a little more straightforward). Even in recent centuries, this has been a problem (see: New World plants being introduced to European diets).
A non-human example: There's a certain variety of monkey that eats some form of vegetation (I forget what) as the primary portion of their diet. It's mildly toxic to them, but they get by. Certain groups of these monkeys, however, have learned that eating bits of charcoal left over by the nearby humans can help with this. This isn't just a simple case of conditioned response; it's cultural information. The knowledge is passed on throughout the group via example and observational learning. Just some food for thought, because I think monkeys are interesting. There are better examples of cultural transmission in non-human primates, but the fact is that even
monkeys are more clever than to have "IS THIS A PLANT? GUESS I SHOULD EAT IT THEN" as the whole of their modus operandi.
Yes, hunting requires a great deal of organization and intelligence, and the importance of that can't be understated. However, your assessment of herbivorous food gathering is way, way off the mark.
Suggesting that humans shouldn't eat meat because it's "wrong" to kill animals that make a vacuum cleaner look intelligent is intolerably obscene.
Er, which animals are you talking about here? If you think a cow, a pig, or a chicken is less intelligence than a vacuum cleaner, then you seriously don't seem to have any idea how animal psychology works. Roombas aren't exactly intelligent. Now if you were talking about flatworms or something, maybe I'd believe you.
Humans stand poised on the verge of apotheosis, and yet some suggest that mindless beasts are our equals?
I don't think anybody is arguing that. At all.
They want to give rights that are not secured even for humans to animals that humans created (selective breeding and the utilization of technology to increase populations far beyond natural levels) for the sole purpose of eating? That's just inexcusable, there's no other word for it.
Er, what rights are we granting them that humans don't have, exactly?
You might as well be suggesting that cars, or toasters, or computers, or cartoon characters have rights.
I have trouble believing that you're even attempting to be rational here. Toasters can't think and suffer, and cartoon characters don't even
exist. It's evident from your tone and the content of your posts that you're coming at this from a very emotional angle. I suggest taking a step back and reconsidering some of what you're saying before posting again.
