Статията в bgfactor наистина е слаба, няма автор ,не са публикувани източници, има и явни заемки от Мулдашев. Постнах я(неудачно) като пример за алтернативна теория. Колкото до ядрената зима и масово изчезване на видове, то нещо подобно се случило (вулканична зима) преди 71000-74000 години:
"... Toba, in Sumatra, erupted explosively about 71,000 to 74,000 years ago. Perhaps 1,000 million tons of aerosols were put into the stratosphere... Mount Toba in Sumatra blew 800 cubic kilometers of ash into the air--4,000 times as much as Mount St. Helens--the largest volcanic eruption in more than 400 million years. Toba buried most of India under ash and must have darkened skies over a third of the hemisphere for weeks. ... a six-year global volcanic winter ensued, caused by light-reflecting sulfur particles lingering in the atmosphere. Average summer temperatures dropped by 21 degrees at high latitudes, and 75 percent of the Northern Hemisphere's plants may have died. ... A thousand-year ice age began ... caused perhaps by an increasing amount of snow that failed to melt over the summer. This snow cover would have reflected more sunlight off Earth's surface, making the world still colder. The effect on humans, who had been enjoying a relatively warm period, must have been devastating. ... Perhaps only a few thousand people ... survived. ... Some anthropologists believe that ...[human]... genetic homogeneity is the result of a "population bottleneck"--that at some time in the past our ancestors went through an event that greatly reduced our numbers and thus our genetic variation. Based on estimates of mutation rates, Penn State geneticist Henry Harpending says the bottleneck happened sometime after ... 100,000 years ago and before a population increase ... around 50,000 years ago. ...".
