    This means bottle gourds would have been domesticated long before any known food-crop cultivation - sometime well before 14000 BP when the Bering land-bridge disappeared.

    If you accept that the Beringia land bridge was necessary to the settlement of the Americas. I still have a suspicion that boat (kayak, raft) transport along the Asian coast, island hopping along the Aleutians, and across the Bering "Strait" could all have been happening at the same time along a migration front a thousand km wide. It's a racing certainty that the people who made this migration did have relevant technologies, because their ancestors had the technology (how did Indonesia and Australia get populated without some sort of boat?) and essentially all of their descendants retain the technology. (The Navajo may not have many seaworthy kayaks, but they're a recent minority.) But ... almost all of the evidence is going to be under up to 100m of sea water, which renders archaeological prospecting decidedly difficult and expensive compared to working on even the wettest of dry land.

    "Bottle" gourds ; now that name might just be a hint of why they'd be a useful crop to any hunter-gatherer tribe. If indeed, they're water-tight enough to be a usable bottle (never met one myself ; wrong continent). But that then raises the awkward question of why they're not found (TTBOMK, but this is a new wrinkle to me) in any of the Asian landmass where you'd expect them to have passed, if they came into the Americas across the Beringia land bridge. Are they "ancient" in any parts of Asia?

    There is also evidence for Taro domestication in New Guinea going back possibly as far as 25,000 BP. If true, this would make it the oldest still-cultivated food crop

    Hmmm, that's a new one on me. Oldest clear evidence of cultivation by a considerable stretch. [Googles] A cursory search yields uncontroversial evidence going back to 9ka BP (The reference "Golson 1977"; I doubt that my local library has that on the shelves!). Ah, I see the 25,000 year BP claim made in the Wikipedia article on the Neolithic Revolution, where it's attributed to "Denham, Tim et al (received July 2005) "Early and mid Holocene tool-use and processing of taro (Colocasia esculenta), yam (Dioscorea sp.) and other plants at Kuk Swamp in the highlands of Papua New Guinea" (Journal of Archaeological Science, Volume 33, Issue 5, May 2006)" (I'm mostly making notes to leave some breadcrumbs for me to follow along.)
    Damn, it's an Elsevier one. And $31 for the full article. Not good enough value to overcome my dislike of Elsevier's predatory influence I'm afraid. The abstract doesn't mention the 25ks claim.
    Hang on ... that bit in the Wikipedia reference about "received July 2005" ; unless it's a typo, that's nearly a year before the article's 2006 publication, which suggest that there's something off the normal track here. Not necessarily "wrong" (a reviewer's comment? Or just a typo?), but odd. And the abstract, figures and tables visible on Elsevier's site make no mention of the startling 25,000 year BP claim which would surely have been the headline of the paper because it's SO much older than anything else.
    Anyway, I've found the guy's recent email address, and I'll try to get the PDF from him. Interesting sidetrack.

    And now that I think a little more about it (I've already sent the email) ... the data that is visible from the paper is not incompatible with evidence for processing of taro (or whatever) which is not necessarily evidence of "domestication." You could get evidence like this from processing of naturally grown plants ; the "gatherer" part of "hunter-gatherer".

    The Younger Dryas cold spell did occur shortly before the mammoths disappeared (~12800 BP).

    Errrr, but what about the Wrangel Island (71N, 179W) population, which persisted until around 5~6ka BP. Even if they were "dwarf" mammoths.

    This is hypothesized to have been caused by a bolide impact or volcanism, but there is no consensus on this.

    It was a nice idea. The evidence isn't strong enough or persistent enough for most geologist to accept the hypothesis (though two considerably smaller events with partly overlapping footprints does remain as a possible interpretation of some of the evidence ; other geologists dispute the validity of even that evidence). If there is consensus, it is that this hypothesis is not a correct explanation for the loss of the megafauna. Well, that's my interpretation of the reports.

    This is also shortly after the Clovis people (precursors to the Native Americans) appeared in North America,

    ... which explains the extinction of the European and Russian populations ... sorry, I don't see the link here. (I accept that there's a good possibility that Clovis spear points did in a lot of megafauna ; in America and Canada. Whether they were preceded by or followed by other types of weapons or by other groups of people is an open question. For sure, it wasn't Clovis spear points that did in the Wrangel Island mammoths so the true story is not going to be simple. If we ever find out what the true story was.)

    and around the time that agriculture was developed in the near east.

    Hmmm, I think that you're a smidgen early there. OK, there was probably some proto-agriculture going in several places, but it's significantly before the development of full-blown agriculture with the associated habitation, dietary and social changes. But that's one where the evidence is under very active research at this moment. Knowing our luck, crucial evidence is having trenches and bomb craters smashed through it in Syria at this very moment. That'd be bloody typical, wouldn't it?

    A single volcanic eruption that could "flash freeze" (your words, not mine) animals tens of thousands of kilometres apart? Or an equivalent asteroid impact. Yes ; such an event should leave pretty clear traces in the geological record.
    These traces are not found.
    Therefore your thesis is not supported by the evidence. Next attempt, please.

    A few years ago there were a couple of people proposing, on very limited evidence, a large "airburst" impact event with regional effects across the North American continent (not across Russia or Europe). Repeat work by them and others has failed to replicate their initial findings, with the proposed impact debris not being found at many sites in the proposed area, or with the levels of claimed impact debris being much lower than found at other sites and indistinguishable from background levels, or them being concentrated in strata of the wrong age. While it was an interesting idea 10-15 years ago, it really hasn't produced the evidence it should have, and no-one really believes it to be correct now. (Not that you'd get this message from the "Discovery" Channel ; it's a very telegenic idea, so they continue to repeat shows that mention it. Cheap TV is not science.) It remains possible that there were one or two smaller "airbursts" in the area, possibly even linked, because there are some unusual particles found. But the single big airburst idea is pretty much dead in the water. Sorry to burst your dreams, because it is an attractive idea. But, to misquote I-forget-whom, it's "a beautiful hypothesis laid low by an ugly fact".

    If someone claims to understand mammoth ecology and environmental preferences, then they're wrong ; we've got some ideas, but they're by no means clearly differentiated and the evidence base for distinguishing between them is murky. One of the things that is pretty clear is that they lived in un-forested areas (OK ; to be more precise, their stomach contents only contain traces of woody material, and the soil around their bodies contains little tree pollen) ; it's considered likely that some ("many"? , but surely not "all"!) populations had a strong annual migration (well, a lot of the remaining Arctic megafauna does ... it's a visibly effective adaptation to a difficult environment.)
