I agree emphatically with Alphagruis. One of the unpopular realities that many people of all dietary stripes seem to have difficulty coming to terms with, is that our ancient ancestors, apparently starting with Homo erectus and continuing to this day, engaged in wanton destruction of other species (both prey and competitor predators) in a carnage unprecedented in the whole history of the planet. Given that hominids began exterminating whole species of animals once they mastered hunting technologies and techniques and continued to do so through most of human history and still do so today, it's unlikely that early Paleolithic humans were particularly concerned with being wardens of the earth. Can you imagine a H. erectus even considering it, much less enforcing it, given that verbal language hadn't even developed? I think the conservation-minded approach likely developed (like most things) out of necessity, once most of the megafauna were exterminated. It's an approach I advocate, but I don't think it was common in the early or middle Paleolithic.
Human history is drenched in blood and we are literally the products of that blood. If human beings have an original sin it is probably the annhilation of countless other species of animals and plants. It's time that we as a species grew up and came to grips with that and stopped pretending, as many vegans are wont to do, that we are a pristine pure species that tasted nary a drop of blood and never harmed as much as a fly and were perfect wardens of the environment until evil modernity arose. I realize that this is an unpopular conclusion (especially with the afore-mentioned vegans and Paleo utopians like brother William), but it seems inescapable to me based on the evidence, and winning popularity contests has never been my goal.
This is definitely not an unpopular motif, even in these forums. The idea that humankind is pervasively destructive with a past and present "drenched in blood" and a future full of doom and gloom with no way out is actually quite common. Its pretty much par for the course when you turn on the radio, TV, or read the latest NY Times bestseller. I've come to understand this reasoning as a form of sociopathy, or at the very least, self-loathing.
Unpopular conclusion indeed but inescapable, I agree with PaleoPhil and definitely disagree with the idyllic view of William
I don't think William's view of the pre-neolithic is idyllic at all. He seems to think mankind had an innate sense of conservation. Why would he not? He knew how to make tools, identify edible plants, harness fire, etc. He could conceptualize, vocalize, count, and make sophisticated art. But he couldn't forecast?
William also (though not explicitly) is pointing out a fallacious argument. Assuming that the past is as messed up as the present is just a form of argument from convention which is a non-sequitor. Do your progenitors some respect at least and show some evidence to back up your claims that they were so inherently destructive and blood-crazed. While you're at it, explain how you're here to explain all this given that you and the rest of the human race should have already perished.
I'm keenly aware that the dominant solution to the megafauna problem is over hunting, at least in uniformitarian circles. I'm also aware that megafauna were large, much larger than elephants which are probably the largest land animal. From my understanding, elephants are already pushing the limits of the strength-weight ratio, so I have no idea how animals significantly larger (like mammoths) even managed to lift themselves off the ground under current gravitational acceleration. I can easily imagine, however, a narrow-minded paleontologist making up a simple but lame theory about humans "killing too much" to answer a complex question.
Also, I wanted to caution many of you here about the doom and gloom. I usually look past it because I know there's good info here. However, more and more, posters are going off-topic with their personal views about how horrible the human race is. If these forums are here to serve people with questions of an RPD nature, then this off-topic nonsense should cease, or you're going to scare people away.
