I just got done watching a video of Dennis Stanford, Head of the Archaeology Division, National Museum of Natural History, Smithsonian Institution at the 2008 Nobel conference at Gustavus Adolphus College. . . . https://cosmictusk.com/original-yd-team-poster-from-acapulco-agu/ – – – Video Title: “Solutreans: First Americans:The Ice-Age Discovery of the Americas: Constructing an Iberian Solution” Dr Stanford, along with Bruce Bradley, put forth the “Solutrean Hypothesis”, that Solutrean and Clovis technologies are one continuous development chain, and that at least THAT line of human incursion into the Americas came from Europe. He briefly mentioned the YD impact hypothesis during his lecture. Then the last question on the 91 minute video was what he thought about the impact hypothesis. He said he liked it. Moderator: “Do you have any comments on that?” DS: “Do I have another hour? I LIKE the meteor strike. I think it’s pretty neat, and I’m really glad thy;re doing it and not me. . . I recall the first time I heard Firestone give his talk was at a meeting we had at South Carolina. . . “And Russell Graham the famous paleontologist and Tom Stafford presented a paper on the Pleistocene extinction. . . and Basically they have all these really nice radiocarbon dates. It’s all ten-nine (10.9 rc kya), just the same time Clovis is moving across the country as fast as they could go. And Edwin Downey Thomas [???] said, ‘Well, they all went extinct, but there has to be an additional reason, that we don’t know.’ And the next paper Firestone gets up and starts talking about the extra-terrestrial impact. “It’s a good idea, and it might explain a lot. Might not. But by using the scientific method and exploring the alternative hypotheses, I suspect that in a couple of years, I might be able to answer this question a little better. But right now I’m pretty sure that Clovis were REALLY good elephant hunters, but I don’t think they had much to do with making those animals go extinct.” That was in 2008. I picked this very early CosmicTusk post to post this comment as being an appropriate place to put it.
