!A recent study found that human brains did not "shrink", contrary to the theory of evolution
New research has been able to destroy previous theories about human evolution, whether biological or social, after confirming that human brains have not shrunk for 3000 years.
Last year, a study appeared confirming that human brains shrank in size 3000 years ago, specifically in the Bronze Age, which was characterized by the establishment of a group of early empires in the ancient Near East, such as the civilization of Mesopotamia, ancient Egypt and others. The collective reduced the need for large brains, as the human being relied on collective information storage more than the individual.
But a new study from the University of Nevada Las Vegas refutes this hypothesis completely, confirming that the human brain has not shrunk for 3000, or even 30 or 300 thousand years.
According to a research paper published last week in Frontiers in Ecology and Evolution, all the results of previous studies were refuted, stressing that the results were in doubt and that 987 of the 1,000 human fossil samples that were supposed to be studied over the 9.8 million years came from the last 100 years only, which means The time frame is neither correct nor neutral.
But why was brain shrinkage originally such a big mystery to anthropologists? Especially since Dr. Jeremy DeSilva of Dartmouth College, a co-author of last year's study, asserted that the unquestionable truth is that our brains are smaller compared to our Pleistocene ancestors, but when exactly did this change occur that deeply baffles scientists?
This confusion came due to the theory of evolution that emphasizes the early development of humans from the genus Homo or even from other creatures such as apes, and the observation of an increase in the size of the human brain from 1.2 to 1.5 million years during the Pleistocene era, so that this contraction came to be the opposite of all expectations.
The modern theory clearly refutes the matter of contraction, and therefore the issue of increasing the size from the beginning is highly doubtful, so that the scientific debate continues regarding the development of man and the way he appeared in his modern form on Earth and the reasons that led to the change in the shape and size of the brain and even the body.
