There has to be a living person that is the very most Neanderthal, it would be cool if the consumer DNA companies consensually released that. It would satiate my curiosity and probably lead to lucrative influencer money for the person revealed
"While 20% of the Neanderthal genome survives today, most people only carry about a few percentage points of Neanderthal DNA, and most Neanderthal-derived DNA is non-coding. Neanderthals maintained a low genetic diversity and suffered from inbreeding depression; consequently most Neanderthal genes were probably selected out of the gene pool...
"Various estimates exist for the proportion, such as 1–4% or 3.4–7.9% in modern Eurasians, or 1.8–2.4% in modern Europeans and 2.3–2.6% in modern East Asians...
"Neanderthal [mitochondrial] DNA (which is passed on from mother to child) is absent in modern humans. This is evidence that interbreeding occurred mainly between Neanderthal males and modern human females.
"There is considerably less Neanderthal ancestry on the X-chromosome... The lack of Neanderthal-derived Y-chromosomes in modern humans (which is passed on from father to son), has also inspired the suggestions that the hybrids that contributed ancestry to modern populations were predominantly females, or that the Neanderthal Y-chromosome was not compatible with modern humans and became extinct."
- We are more likely to be morning people.
- We have greater risk of sunburn.
- Higher likelihood of balding.
- Greater mechanical pain sensitivity.
- (Sometimes significant) effects on immune and antiviral responses.
- Some variants have increased risk of allergy.
- Some variants linked to larger lung capacity.
- Some associations with bone density.
- Neanderthal variants influence nose height and shape.
- Some variants linked to fewer miscarriages.
- Some variants associated with younger menopause.
- Strong statistical associations with smoking behaviour (more likely).
Also he's a pretty good actor.
A more popular example seems to be giant Russian boxer Nikolai Valuev, who sports some serious brow ridges and a lower forehead, but still has too much chin.
