Interesting, but the lack of  any Neanderthal DNA at all is suspect..  Judging 
by our previous registered list Neanderthal, there may be a positive 
correlation between percent
Neanderthal DNA and photographic skills.  A brief look at recent developments 
revealed that a previous postulate of loss of some Neanderthal DNA from the 
genome due to negative selection bias was due to methodological issues.  


There may be some enrichment of Neanderthal in East Asians but a recent article 
cell more precisely defined the average Neanderthal DNA in Europeans at 1.7%. 
The previous variation had been overestimated--sad for our registered 
Neanderthal but probably good news for Chris.  
Interestingly, there clearly is some Nean. DNA in Africans as well, which was 
not appreciated.

Highlights from 2020 Cell article. 
IBDmix detects archaic ancestry without using a modern human reference 
African individuals have a stronger Neanderthal ancestry signal than previously 
Evidence of back-to-Africa migrations contributing to Neanderthal ancestry in 
****Variation in non-African Neanderthal ancestry has been overestimated******

Stars are mine. 

Probably 1.7% Neanderthal DNA, Mike
