Our ancestors seemed to have the ice age better, because they were all used to say goodbye to the life of the collectors and Jagery
At the keyword ice age, most people probably think of a crowded Eichhornchen, which spoken by the comedian Otto Latino Sid, a well-graved mammoth named Manni and a talking sabel tooth tiger. Now it was allowed to be clear that it is a completely outgoing story – but also the scientific facts of the age, in which the film series plays, have bent the ICE AGE makers together.
An example of this are the urbans who encountered the colorful troupe in one of the consequences. They obviously beat as a Jagery through the life that goes away from meat and fish (but under no circumstances of faults) and drag freely through the inhospitable land.
In fact, the cold periods have apparently appreciated the adaptation of man to a sessy lifestyle. In any case, with agriculture, our ancestors did not start until long after the end of the ice age, as it is often accepted, but already at their end. In any case, the finds of Chinese researchers show that they report in the publications of the US Academy of Sciences (PNAs).
The researchers are offering themselves on the investigation of three grindstones, which had already been found early in an excavation bar in the valley of the Quining Hui River, a tributar of the yellow river in Shanxi province. The small settlement has about 23 there.000 to 19.500 years – at a time, as the ice covering of our planet reached its maximum extent. In the excavation area, the climate was cold and dry at this time, the vegetation must have been stepped-like.
The fact that the observes are indispensable about abrasive or grinding stones, at least for an extensive enjoyment of vegetable food speaks. What stood on our ancestors on the menu revealed traces on the tools that the researchers could now locate. Apparently, numerous plant parts were processed, which could assign the archaologists to multiple interesting species. Including different types of subgrasters, including today’s cereal types, such as wheat, rye and oats.
But various Vigna bean species identified the researchers who are used today, among other things, in the form of munging bean. Yams roots, in Sudamerika and Africa are still popular, were also part of the kitchen like the Bitter cucumber not relatives with our cucumber, Kirilovii, who also used in traditional Chinese medicine. The grinding stones with which the people of the Palaolithic prepared their food must have been located in the nearby fire, because there were also overrests of charcoal on it.
That our ancestors have already begun with the use of grasters, beans and tanks, so the researchers, the way to their own cultivation of resources, ie for agriculture, considerably facilitated. And apparently it has also allowed the survival of the former humanity in an inhospitable time at all.
