Cat eye pupils was a stupid marketing mistake by Vendramini. While I do not rule out cat eyes, depicting them in art was nothing more than giving a great point to condemn his entire theory, as you so regularly prove. Every other aspect of his theory is on the mark:
* Nocturnal behavior mostly explaining the large eyes. I will agree that extensive cave use, northern latitudes, and forest dwelling are contributing factors, but nocturnal hunting would be rhe most prevalent factor.
* Hirstute bodies. Unlike African and west Asian homo sapiens, Neanderthals were likely covered in hair.
* Predatory behavior toward homo sapiens, whether or not they ate their human cousins. Homo sapiens kill each other with regular glee, so to imagine that Neanderthals did not would be almost stupid.
Vendramini made a really stupid mistake with his marketing cartoons. In order to deal with foolish scientists, one must deal with them like a lawyer deals with a judge and jury........IOW, a collection of fools. He chose the fantastic approach. He handed them the scourge that they use to whip him. He isn't the broken clock; science as an industry is. It's only correct when the hands are physically moved to the correct moment, and even then it's only an imagined representation of time as mankind misunderstands it.
