Neanderthals, who ranged from Western Europe to Central Asia, probably had the same distribution of skin color as modern humans, including fair skin and freckles. Fair skin is an advantage at northern latitudes because it is more efficient at generating vitamin D from weak sunlight. Freckles are clusters of cells that overproduce melanin granules; they are triggered by exposure to sunlight and are most noticeable on pale skin. BNC2 is one of several skin color genes and it influences saturation of skin color and freckling. It is a Neanderthal gene and is found in Eurasian populations, most commonly in Europeans (70% have at least one copy of the Neanderthal version).
According to this ppl with light skin got that from neanderthal genomes, so I am thinking whether this has anything to do with preferences of mate selection...
It seems like European descent ppl tend to have a fondness for dark skin women, where as Asian ppl don't.
Recent research suggests, people in China, Japan and other East Asian countries have about 20 percent more Neanderthal DNA than do Europeans. It is now scientifically irrefutable fact that the "human species" has been found to contain a substantial quantity of DNA (at least 20%) from other hominid populations not classified as Homo sapien; such as Neanderthal, Denisovan, African archaic, Homo erectus, and now possibly even "Hobbit" (Homo floresiensis).
If not given drugs to prevent infant death, the pregnant body of a rhesus negative mother will attack, try to reject, and even kill her own offspring if it is by a rhesus positive man.
The Domestic dog (Canis lupus familiaris) is a sub-species of the gray wolf (Canis lupus), and they produce hybrids.
There are numerous other examples of where two separate species (for example with different numbers of chromosomes) can also produce viable offspring, yet are considered separate species. That said, humanity has been shown to be, genetically speaking, a hybrid species that did not all share the same hunter-gatherer ancestry in Africa.This means humans are not all the same race, out of Africa theory is debunked!
1. African DNA found in Yorkshireman
In 2007 the Daily Mail ran a report on John Revis, a Yorkshireman who was so blond and blue-eyed when he was younger that he thought he was directly descended from Viking or Anglo-Saxon stock. However, when his DNA was analysed as part of a wider study linking the male Y-chromosome to northern surnames, he was found to be haplogroup A1.
John RevisA1 is very rare and highly specific to west Africa. John Revis shared this genetic match with 7 other northern Englishmen with the surname Revis. He had traced his direct paternal line back to the mid-1700s and found his ancestors where mostly bakers from the north of England; there was nothing in his family history to suggest recent African origins. However, his DNA presented the first genetic evidence of Africans living among ‘indigenous’ British people.Africans were first recorded as being present in northern England 1,800 years ago, when they formed a contingent of the Roman garrisons defending Hadrian’s Wall against raids by Scottish tribes. Much later in the 16th and 17th centuries the slave trade also brought an influx of Africans to the British Isles, and by the late 18th century there were around 10,000 black people living in Britain. Some former slaves rose quite high in society.
It is possible that John Revis descends directly from the north African clans that comprised a small part of the armies of Roman Britain from 43 – 410 AD, but the Roman occupation left only a tiny genetic footprint on the modern English population and it is thought more likely that the source of his African DNA is a slave from West Africa.
The contributor of the A1 chromosome to the Revis surname may not be its founder. He may have been a first-generation immigrant African, or a European-looking man carrying the A1 Y-chromosome introduced into England some time earlier. It could have been many generations earlier, with descendants of earlier lineages now extinct, or not yet tested.
Could ppl with African genes that look white find dark women more attractive than ppl who don't? I am thinking that the preferences might not be just cultural but it is embedded in your genes.
