From about 32 kya to 22 kya, prevailed in Europe. That culture produced the and art such as the . By 20 kya, . But as far as human expansion is concerned, the Gravettian (and related cultures) are most notorious as mammoth hunters extraordinaire for those that lived on the near the ice sheets. To , they could not swim to Sahul, but flourished everywhere else they could get to. At , they were the ultimate hunter-gatherer kill. Also, near the ice sheets, meat could be stored in the ground. Cro-Magnons did just that, and that “freezer” full of meat led to the first seasonally sedentary humans. It long predated the Domestication Revolution when people could be sedentary year-round, but while the megafauna lasted, the first signs of what came later appeared as Cro-Magnons created villages around frozen mammoth meat. Gravettians hunted along migration routes and set traps and ambushes for mammoths. For thousands of years, mammoths were the primary focus of Gravettian hunters, and many scientists believe that humans at least . Gravettians probably used the bow and arrow, and using poisoned arrows on mammoths would have been child’s play, not a hazardous undertaking. They also tended to focus on the easy meat: the young, relatively defenseless, tender mammoths. Killing the offspring alone would have driven the slowly reproducing mammoths to extinction, and as the interglacial period began around 15 kya, there would have been new pressures on mammoths. One of them was that fewer mammoths meant that they were not terraforming their environments like they used to, and the warming climate probably reduced their range. For a mammoth facing humans, there was literally no place to hide (except maybe in the living room), and there is little reason to think that hunters would have eased up when mammoth numbers dwindled. If anything, their efforts would have to get the last ones, as they competed and fought over the final mammoths. In one lifetime or even several, the changes would have been barely noticeable, if at all. There was simply no way out for mammoths, and they went extinct south of the European ice sheets under the ministrations of Cro-Magnon hunters. More evidence of their fate is some mammoths surviving in refugia: islands where humans did not arrive until thousands of years later. mammoths survived on in the chain off of Alaska until less than six kya, and went extinct when humans arrived. Several hundred apparently full-sized mammoths survived on near Siberia and went extinct less than five kya, when humans arrived. In today's France and Spain, Gravettians also semi-settled along the migration routes of reindeer and red deer. From Spain across Europe, into today's Russia, Gravettians hunted migrating herds, and not only the mammoth was driven to extinction, but also the wooly rhino, the Irish elk, the musk ox, and steppe bison were driven to extinction as the ice sheets retreated. Neanderthals had been ambush hunting in similar fashion, and those animals, like the African megafauna, grew wary of humans, and killing those animals probably took planning and guile.
The culture’s killing implements abruptly appeared in the archeological record and disappeared just as fast, after the easily killable megafauna went extinct. Today’s North American megafauna are , not North American megafauna that learned to avoid humans. Bison are the only significant exception, although they came from Asia, too, and explaining their survival remains a minor curiosity, but is about the only circumstance not neatly aligned with the overkill scenario. The “” paper concluded that although the South American extinction was the greatest of all, it is the most poorly investigated and that the overkill hypothesis cannot yet be attached to South American extinctions. That may be a prudent position for a specialist who pronounces judgment only when all the evidence is in, but I will be among the most surprised people on Earth if the pattern of 50 thousand years did not continue there, especially since it had no ice sheets. There can be no more pertinent example than comparing Africa to South America. They inhabited the same latitudes and have similar climates, separated by the Atlantic Ocean. Africa was the home of humanity, where its animals had millions of years to adapt to the human presence, and Africa only lost about 10% of its megafauna (probably to human hunters with their advanced weaponry) while South America lost nearly all of its megafauna, and quickly. Climate change did it? How could it have even contributed?
As scientists have been putting this picture together, one irony is that Cro-Magnons had black skin, and Neanderthals might have had light hair and eyes, as an adaptation to the cold climates that they lived in, as with Europeans today. It turns the racist aspect of on its head, and has been noted in some scientific corners. For the remainder of this essay, as all other human species were extinct but for the “hobbits” by 30 kya, the word “human” will refer to behaviorally modern .
My astronaut colleague investigated the UFO phenomenon early in his adventures on the and immediately after refusing an "offer" to perform classified UFO research for the American military. It became evident that the UFO and free energy issues were conjoined. A faction of the global elite to a close fellow traveler, which included free energy and antigravity technologies. My astronaut colleague was involved with the that some around me were, who invented a solid-state free energy prototype that not only produced a million times the energy that went into it, but it . I eventually understood the larger context of our efforts and encountered numerous fellow travelers; they reported similar experiences, of having their technologies seized or otherwise suppressed, of being incarcerated and/or surviving murder attempts, and other outrages inflicted by global elites as they maintained their tyrannical grip over the world economy and, hence, humanity. It was no conspiracy theory, but what my fellow travelers and I learned at great personal cost, which was regularly fatal.
So what is self-regulation in writing.
Surveys the fundamentals of criminal investigation procedures and techniques. Examines crime scene search and collecting, handling, and preserving evidence.
For example, you might have a topic sentence like one of these:
The ten weeks of English class has been interesting and fruitful, I have learnt a lot of writing and reading skills that have indeed helped me in improving my English....
Well written essays turn the hearts of the people.
I continued to and became my . My former partner is the Indiana Jones of the free energy field, but I eventually realized that while it was awe-inspiring to witness his efforts, one man with a whip and fedora cannot save humanity from itself. I eventually took a different path from both my partner and astronaut colleague, and one fruit of that direction is this essay. Not only was the public largely indifferent to what we were attempting, but those attracted to our efforts usually either came for the spectacle or were opportunists who betrayed us at the first opportunity. As we weathered attacks from the power structures, such treacherous opportunities abounded. I witnessed dozens of attempts by my partner’s associates to steal his companies from him (, , , ), and my astronaut colleague was twice ejected from organizations that he founded, by the very people that he invited to help him. During my radicalizing years with my partner, I learned that , and it is the primary reason why humanity is in this predicament. The antics of the global elites are of minor importance; the enemy is us.
