All those details are merely incidental recent developments, though. They've had a huge impact but humans have only been pastoralists for the past few thousand years.
Essentially we're mammilian velociraptors- we use teamwork and tools coupled with our massive endurance to take much larger prey than many mammals our size. Remember- humans do have a lot more endurance than many animal species- we're specialised for long distance chases. Whack a spear into a bison and track it til it falls.
Also we have dogs.
My point was... Can we STILL be considered preditors? Maybe a few of the tribal pople left on the planet, but I sincerly doubt that most of us in both the west and east have what it takes to engage in a weeklong hunt, to stalk prey and eventually kill it using brute force. Perhaps this really has no bearing on the current topic being discussed, but I feel its a point worth mentioning.
Also I'd have to dissagree with your assessment that Humans are mammilliam velociraptors. Sure we use teamwork, so do other pack animals. Additionally, as far as we know Raptors didnt use tools, the giant talon on their foot used for eviceration was really all they need... that and teeth. No campfires, no storytelling tradition, nothing would really lead me to believe that velociraptors are anything like people save our common lust for blood and violence.
As a side note, I wonder if the the Frilled Neck Lizard, which is a strict carnevor could be considered somwhat of a biped, as it runs... nay, sprints on its hind legs.
