Wonder what they might have thought about hunting today's swamp creatures. nypost.com/2021/01/14/cute-piggy-drawn-45500-years-ago-may-be-first-animal-doodle/“They’re very, very small, little pigs, but these ancient artists portrayed them with such resplendent fatness, which I imagine was something to do with their interest in killing the largest and fattest pigs they could find, which yielded the largest amount of meat and protein,” said Adam Brumm, first author of the study, speaking to National Geographic. So incredibly long ago! |

Two things 45k years ago it was an ice age and well into it, so sea levels 140M lower, that region is a little "move" prone but not that much.
Most of the worlds people lived by water and also the sea mostly. So most of the historic artifacts are under the ocean we have as a consequence a limited number of sites to find and work on from that era.
Carbon dating and all the other methods are getting better that does not eliminate a site contamination possibility but its at least plausible.

The ocean has always been the most reliable source of food. Some folks find food a rather important item in life.
Once agriculture became predominant, risk of food deprivation became magnified. Weather is always a huge risk in agriculture. Also a risk in seafood, but the windows of risk are much shorter.
Today, there are too many people to feed from the ocean alone. As a result, land based food sources are critical.

Most of the worlds people lived by water and also the sea mostly. So most of the historic artifacts are under the ocean we have as a consequence a limited number of sites to find and work on from that era. Carbon dating and all the other methods are getting better that does not eliminate a site contamination possibility but its at least plausible. Plausible is the story of science. When one starts weighing one's own plausies as superior to the "unknowns" is when it gets stuck.  A lot of grains of salt here. The earliest "R" haplogroup (Europe is largely R1) male so far identified was found in Central Siberia in a tributary draining Lake Baikal. Dating states circa 24,000 ybp. Another "R" find in the same general area dates to circa 17000 ybp. Next set of documented R1a and R1b finds are in Russia and Sweden dating to circa 7500-8000 ybp. By 7000 ybp our ancesters were spread across the Pontic steppe, taming horses, herding cattle, building wagons and smithing metal. The latter may have been picked up from others that developed copper mines in the Carpathians and Caucucus before that. Not to mention Gobekli tepe which may have been around from 11000 or so ybp. Those who maybe documented the comet coming, if so they did. Genealogists have been using the number of ydna mutations from a base set (together with other techniques when available) to date when new haplogroups appear on the scene. These mutations are assumed to be random. A mutation occurs when there is a substitution in one of the nucleotides in the composition of one of millions of locations on the ydna chain. So ... it takes 16000 years for R to mutate to R1a and R1b (2 mutations across 11,000 years or 5500 years per), another 7000 years for R1b to go to R-M269 (4 mutations or 1750 years per). The rate keeps dropping as the population continues to increase. But they assume that the rate of mutation for any given individual does not change significantly. Seems that might be questionable. For example, could cosmic ray levels (or something else) change mutation rates? Long, long story, with scientists stuck on their favorite methods ... just like in climate scientists. The Celtic R-U152 mutation shows up circa 4500 ybp ... another 8500 years with 7 mutations, or 1200 years each. By 3800 ybp, my S47 clade arrives (700 years and 4 mutations - 175 years per). And the rate just keeps declining. Who were these 45,000 year olds anyway? |

I didn't have anywhere else to put this ... When Our Earth Flips Every 12000 Years Yes I immediately thought about the the Dzhanibekov Effect. Shown here: But your link to William Astley here solarcycle24com.proboards.com/post/164125 shows that there are ways for the major axis moment of inertia of the Earth to change in just the way that Dzhanibekov noted it doesn't have to be by a lot after all. This was all described in "Earth In Upheaval" by Immanuel Velikovsky which I read decades ago and which is based on a similar idea. Perhaps the year 2020 missed a trick  So this year we could get >an X-100 super CME, >the Yellowstone Caldera, >the San Andreas fault, >La Palma Cumbre Vieja volcano landslide and tsunami .... Get out of that preppers!!  |

Fried, baked, shaken and drowned. And a wee bit of the flu. All in all, a good year.
