What evidence would a massive comet strike in Antarctica leave? Probably just tales of a massive flood, massive depopulation, and an angry God, I guess...
My guess has always been that the impact happened on the North American ice sheet, triggering a collapse of a previous rise in the Mid-Atlantic plate, pounding Atlantis with a tsunami and dropping it into the sea, allowing warmer currents to reach the Arctic ice, and creating a massive rise in sea level around 10,000 B.C., corresponding to the Younger Dryas.
Or something along those lines. It wouldn't have much of an effect on Antarctica, at least not until global temperatures rose.

You could and should write your own thread along those lines.

Thanks Slayer, your threads are always so thought provoking, and I love spending the time pouring through all your data and links and the additional comments of members. I'm putting my mark on here now for my ATS, and will take the weekend to indulge my historic fantasies!
In the past there have been numerous theories for the cause(s) of autism, Asperger's syndrome, ADHD and Tourette syndrome. Most of these theories can at best explain small parts of these diverse syndromes. Many of them extend their findings in spectacular ways to be able to claim to explain larger parts of the autism spectrum with little success.
This theory approaches the problem from a new radical viewpoint. Instead of approaching autism as a disorder, brain defect or the result of poor socialization or parenting, it claims that autistics are fully functional.
All the areas that are central to autism are related to species-typical adaptations that vary widely between species. These include nonverbal signals, social organization, sensory acuteness, motor skills, general preferences, sexuality, physical traits and biological adaptations. Some of this diversity in autistics is poorly understood and virtually unresearched and therefore is not published in peer-reviewed journals. Because of this lack of research, Aspie-quiz, an online questionnary, is heavily referenced for these traits.
Recent genetic research have demonstrated that the Out-of-Africa (OoA) model with no interbreeding fails to explain nuclear DNA diversity in Eurasia. Several models of interbreeding that do explain this diversity exists today. It therefore is quite likely that Neanderthals contributed to the Caucasian genome. Aspie-quiz have demonstrated in a large survey in the US population that Afroamericans have only 1/6 of the autism prevalence of Caucasians. The same survey also indicates that Asians and American Indians have about 1/2 of the autism prevalence of Caucasians.
Principal Component Analysis (PCA) of Aspie-quiz yields axises that seems to be related to the first Eurasian Homo, the formation of modern humans in Africa or South Asia and the hybridization between modern humans and Neanderthals in Europe. These axises seems to be 1.8 million years, 150,000 years and 37,000 years, which fits pretty good with the archaeologic evidences available.

Star and Flag! I enjoyed the thread, Slayer. You put together everything I had disjointed thoughts on. Thanks for putting the pieces of the puzzle together. I'm glad your notion contained only human and hominid explanations and nothing extra-terresterial. I always thought interbreeding of humans with hominids accounts for the various races of man.
If, as it is presently accepted that modern man had interbred with Neanderthal and Denisovians wouldn't there have been a cross over period producing a half-breed/hybrid species? One which would have had possibly physical characteristics and mental attributes of both?
I'm not attempting to say they would have been a "Super Species" but something not quite us and not quite them. Also depending on where they lived they could have had varying physical characteristics and mental attributes of both to varying degrees.
the improved or increased function of any biological quality in a hybrid offspring. It is the occurrence of a genetically superior offspring from mixing the genes of its parents.
does any one else picture a neanderthal sitting in a chair and pointing and saying "make it so."? couldn't help myself seeing that picture of patrick stewart!
