Then why was much of the mega-fauna extinction limited to the Americas?
Here's a classic example of the conflicted PC-person.

Here, the claim is made, "Worldwide, there is no evidence of Indigenous hunter-gatherers systematically hunting nor over-killing megafauna."
This is in blatant conflict with exactly that happening in NZ and Madagascar.
You might point me to where I can study the remaining megafauna in Europe and Asia, excepting the Asian subcontinent where elephants still roam. As far as I can tell, Australia, with the exception of some overly large marsupials, never had much else in the way of megafauna to start with. A quick search indicates there were mammoths/mastodons on the African continent at one time. I didn't look any further to determine when they went missing. NZ and Madagascar???
There are so many anamolies associated with this time period that trying to put the blame on humans seems a PC endeavor at best and unmitigated propoganda at worst. There are indications of potential cosmic origin, along with pole wanderings, massive volcanism, flooding and enormous waves traversing entire continents; you get the idea...
From this SEARCH check out the first ARTICLE re boneyards in Alaska and almost complete islands composed of mammoth/mastodon remains in and north of Siberia.
I haven't looked at your posting history so I don't know if you're a hit and run type or not. It is a curiosity to me that some people, when offered compelling data opposing their views, fall off a cliff, or something. You are still around, aren't you???
No matter. SunkenCiv probably spent a good deal of time compiling a somewhat dated(now) but exhaustive FR list on the subject that you might find interesting; or not, HERE.
Let me know if you would like to see additional stuff or if you would just as soon discontinue the conversation.
