Even 50,000 years ago there would be less than 1% DNA trace. This author is just ignorant. My Great Great Grandmother only gives me 12.5% of her genes so my 4th great grandparents would give me about 3%. That is a long way form 50-80 thousand years ago.

Not exactly. Your folks may give you genes that distinguish you from other humans, but there are LOTS of genes that we all have in common (how your pancreas work and is built, etc.) I wouldn’t be surprised if 99% of human genes are ones we all share.

You're assuming that the person got 'one shot' of Neanderthal genes 50,000 years ago and that was it. They may have been getting a mixed % of Neanderthal genes from each generation...not just once.
