This side-by-side graphic comparison is a prime example of the unprofessionalism that dominates the whole paleontologist dream factory.
What are the first "contrasts" that strike the eye?
1. The bone color. The modern is depicted as off-white, the neanderthal is decked in markedly different yellow. In other domains of human endeavor, this would be called "deceit."
2. Height. The neanderthal is depicted at 5'4", the modern as 6'0". Why 6'0"? Modern well-fed man has a wide range of heights, and in the centuries before the 20th, 5'4" was probably exactly average for a male. Again, these depictions are about dreams, foundation grants and reputations, not about facts.
Beyond this, the current variants of the human family are widely varied. Just go to the beach sometime in a racially diverse area and take note of the wide variation in "upper leg to lower leg" ratios or the differing pelvic structures of different races and nationalities. Combining this with the lack of actual Neanderthal material, this seems to be a report angling for more funding, nothing more.
