In a recently conducted study, a multidisciplinary French-American research team with expertise in archaeology, past climates, and ecology reported that Neanderthal extinction was principally a result of competition with Cro-Magnon populations, rather than the consequences of climate change.
The study, reported in the online, open-access journal PLoS ONE on December 24, figures in the ongoing debate on the reasons behind the eventual disappearance of Neanderthal populations, which occupied Europe prior to the arrival of human populations like us around 40,000 years ago. Led by Dr William E. Banks, the authors, who belong to the French Centre National de la Recherche Scientifique, l'Ecole Pratique d'Hautes Etudes, and the University of Kansas, reached their conclusion by reconstructing climatic conditions during this period and analyzing the distribution of archaeological sites associated with the last Neanderthals and the first modern human populations with an approach typically used to study the impact of climate change on biodiversity.
This method uses geographic locations of archaeological sites dated by radiocarbon, in conjunction with high-resolution simulations of past climates for specific periods, and employs an algorithm to analyze relationships between the two datasets to reconstruct potential areas occupied by each human population and to determine if and how climatic conditions played a role in shaping these areas. In other words, by integrating archaeological and paleoenvironmental datasets, this predictive method can reconstruct the regions that a past population could potentially have occupied. By repeating the modeling process hundreds of times and evaluating where the errors occur, this machine-learning algorithm is able to provide robust predictions of regions that could have been occupied by specific human cultures.
This modeling approach also allows the projection of the ecological footprint of one culture onto the environmental conditions of a later climatic phase―by comparing this projected prediction to the known archaeological sites dated to this later period, it is possible to determine if the ecological niche exploited by this human population remained the same, or if it contracted or expanded during that period of time.
Comparing these reconstructed areas for Neanderthals and anatomically modern humans during each of the climatic phases concerned, and by projecting each niche onto the subsequent climatic phases, Banks and colleagues determined that Neanderthals had the possibility to maintain their range across Europe during a period of less severe climatic conditions called Greenland Interstadial 8 (GI8).
However, the archaeological record shows that this did not occur, and Neanderthal disappearance occurs at a point when we see the geographic expansion of the ecological niche occupied by modern humans during GI8. The researchers' models predict the southern limit of the modern human territory to be near the Ebro River Valley in northern Spain during the preceding cold period called Heinrich Event 4 (H4), and that this southern boundary moved to the south during the more temperate phase GI8.
The researchers conclude that the Neanderthal populations that occupied what is now southern Spain were the last to survive because they were able to avoid direct competition with modern humans since the two populations exploited distinct territories during the cold climatic conditions of H4. They also point out that during this population event contact between Neanderthals and modern humans may have permitted cultural and genetic exchanges.
They should have has GEICO insurance policies............
“HA HA! Neanderthal. Can’t make fire” - The Far Side
I thought there was some inbreeding between Neanderthal
and Cro-Magnon, meaning “they” are still with us today...
But I want to hear what Blam has to say about it.
Wait a sec, how was there climate change back before we had cars? This doesn’t make sense... /s
So what we are saying...is that Yurg and Randy couldn’t survive in a world with each other...so Yurg had to go?
What about evolution? Couldn’t Yurg just evolve? Couldn’t we just turn up the old Yurg and make him a better and improved Yurg? Are we saying that Yurg was just a loser and couldn’t make it in a modern world?
I think we are looking at discrimination.....clearly here. No doubt. If only Yurg had real rights and marriage rights....he might have survived on...maybe. What we haven’t said here or hinted at....is that Yurg might have been a Prop-Eight kinda guy and he kinda non-produced himself out of existence.
Maybe Duck with Mango Salsa is bad for the nad?...............
LOL, I was thinking more along the lines of the Far Side cartoon, showing the real reason the dinosaurs became extinct.
My personal theory is they migrated out of Europe into the Middle East and became Arabs.........
Conclusion: We must do away with all forms of competition, specially the free enterprise system!
But wait... isn't that what the "Globull Warming" hoaxers are all about?
“Zog Jones cooks his meat”.
Blame it on the Neanderthal’s lack of secure borders.
It is my opinion that we are Neanderthals. All the evidence/data is against that position but, I still believe it.
I think we have an AHA DNA moment in our future that will validate my belief.
That smokin’ll getcha every time...
“an approach typically used to study the impact of climate change on biodiversity.”
They THINK! They don’t really KNOW! They just wanna get paid. Of what importance is this? Money could be spent much more wisely.
Pertaining to Abraham’s son, Ishmael (Father of all Arabs) , by Hagar the slave of Sarah:
Genesis 16:12 (King James Version)
12And he will be a wild man; his hand will be against every man, and every man’s hand against him; and he shall dwell in the presence of all his brethren.
I think that at least some of the inbreds are employed at our local newspaper, The Times Reporter in New Philadelphia, Oh.
Mr. Blam, sir,
I always appreciate your thoughts and comments on this and similar subjects.
I know you have put a lot of time, effort, and thought into the matter.
Here’s me wishing you a 2009 that is full of healthy dogs and free of storms.
