Depictions of neanderthal are just pseudoscience and artist's renditions,
The DNA evidence indicates that whites have the most neanderthal DNA and that it is neanderthal admixture which defines more civilized races.
There is a long running hoax about jews having more neanderthal admixture, this is a psyop designed to prey on notions of racial purity in white nationalists and supremacists but also give jews a claim to europe. There are many downstream benefits to jews and detriments to whites for running this hoax in the social paradigm jews have engineered.
As to the skull itself, the most complete skulls are female skulls and there are no neanderthal jaws, further the inner volume of the most complete skull indicates a larger brain than even modern Europeans.
This rendition exaggerates everywhere possible.
