As I've shared before, I have confirmed Cro-Magnon European Early Modern Human, Neanderthal European Archaic Human and Denisovan Eurasian-Siberian Archaic Human genetic ancestors. I've also shared a scientific skull comparison video (included below) that European Cro-Magnon humanity is likely a hybrid (at least) of European Neanderthals and European Early Modern Homo sapiens. In the video, scientist Dr. Justin Marley (Chair Mental Health Informatics Group, UK Royal College of Psychiatrists) notes that expanded portions (relative to modern Homo sapiens) of Cro-Magnon and Neanderthal brains (as evidenced by the cranial brain cases of both) are located in the region where the temporal lobe meets the occipital cortex.
The temporal and occipital areas of the brain are generally responsible for memory formation, memory management, naming objects (a function of language), whole-object integration, visual recognition, vision and auditory ability. More specifically responsible for symbolic thinking, information processing, cognitive insight, language comprehension and the ability to communicate coherent ideas (vocal, written and signed), Wernicke's area is located in superior temporal gyrus in the temporal lobe.
These functional areas of expanded brain structure support the existence anomalies of memory as found in some modern humans (like myself and the völva of ancestral tradition) of European Cro-Magnon and Neanderthal ancestry. It also supports with physical evidence the idea that Cro-Magnon and Neanderthal humans in Europe had a brain biologically wired with an expanded, and therefore likely enhanced, ability for memory management, whole-object integration, information processing, symbolic thinking, language comprehension and language communication.
Cro-Magnon and Neanderthal human brains were structurally optimized for creating written symbolic language. The brain structure of Old European humans and the paleolithic cave art symbols of Old Europe support the location of the birth of writing to be Old Europe.
