On a thread about Vietnamese affirmative action discussion derailed to the ancestral relationships of East Asians. It is better in a dedicated thread. http://www.politicalforum.com/showthread.php?t=345456&page=2
C11 codes for light skin so all we know is the common ancestral group had darker skin. Note also how your source supports migrations into Asia, not that two East Asian tribes created Caucasoids as you said. Australoids may be from a prior migration but Negritos are from the same ancrstral group as East Asians. We know EDAR affecting Asian hair and skin, and epicanthic folds developed after the split in East Asia, so it is trivially false to claim the Eurasian ancstral group looked East Asian. They would have been dark, curly haired, and wide eyed, much like Negritos.
Asian hair and skin, and epicanthic folds developed after the split in East Asia These could have been features present in a more archaic humankind living in Asia, while Neanderthal roamed Europe. Chinese anthropologist claim their most modern H. erectus demonstrates Asiatic flattening of the cheek bones. I look forward to the revelations of some H. erectus genome. Moi No
http://www.cell.com/abstract/S0092-8674(13)00067-6 Flattening of the cheekbones coevolved with increased cranial capacity as the jaw needs a more posterior anchor point. Especially it occurred in North East Asia. I do not rule out pre-Sapiens East Asian hominid influences on modern East Asians however and this may be part of the story.
Imagine y'got a bunch of narrow faced humanoids around and then, flattened cheek bones begin to occur, widening the face - an attractive feature to all PeopleKind, a wider face - and voila Sexual Selection. Those excuses expressed above do not meet with the European and Sub Saharan PeopleKind experiences. Those flattened cheek bones are of Asia. Likewise the development of Caucasians and the archaic peoples they encountered, such as Neanderthal for that football shaped cranium. Now there is an advantage! More surface area for the same volume. And "brain" is about more surface area, not volume. (That's why we rule the globe) Moi No
Halpogroups only show human migrations .... You are saying that local erectus bred with sapiens ? while not impossible it is not proven so far, we only know that Denisovans mixed with an "unknown species" . Almond eyes and flat faces have probably evolved in windy and snow covered areas (Inuits did not need sunglasses) but from the crappy stone tools in Asia the most possible hypothesis is that the majority of population lived in subtropical areas with bamboos . So far ALL Asians tested have Y chromosome markers that trace back to two African populations .... and those markers do not lie !
current genetic evidence appears to indicate sapiens were only barely able to exchange genetics with our close relatives the neanderthals, exchanging genetics with even more distantly related homo erectus would appear to be highly unlikely...
The genetic split with Europeans caused by the lighter skin mutation occurred around 50,000 years ago and there was no possibility for East Asians to mix with H. erectus after the split as they were already extinct and any genetic contributions from Neanderthals or possibly H. erectus to the common ancestors of East Asians and Europeans are equally shared among them. East Asians are known to have higher percentages of Neanderthal DNA than Europeans and it was East Asians who directly interbred with Neanderthals and Neanderthal DNA was passed on to Europeans as they went separate ways with the A111T mutation.

YOU are asking a 21st Century humanoid to be mating capable with some primitive. I subscribe to the concept but forth by Chinese anthropologist, and myself - that continuity is maintained in the species via continuous hybridization. All though time. Okay, maybe their off spring did have a worse chance of viability for some reason, could have been cultural. But, obviously some of their off spring did "take", and even gave us north of the Sahara folk an active immune gene, and maybe the tendency to auto immune disease too. REMEMBER, my friend, 20 years ago you would have been uploading Neanderthal was completely replaced by modern folks with no genetic exchange because you worship what other's write without critical thought. style. It is more likely those H. erectus created the flat cheek boned Asian look than the latest out of Africa folks developed it again - independently. Si? The Races, such as they are may well be influenced by the archaic PeopleKind's genetic contribution to the last wave or the "out of Africa" folks whose women probably developed the higher fertility of the monthly cycle, like African goats, compared to their EurAsian cousins - goats and people too. WHEN you read that in a "book", remember you heard it from a thinking first. Moi View attachment 25709
we 21st century folk are essentially no different than those who left africa 70k ago.... when sapiens arrived in china 45k years ago there is no evidence that they coexisted with homo erectus, there is no evidence homo erectus was even alive at that time... as I've told you before 30yrs ago I proposed there was a sapiens neanderthal genetic exchange...but the difference was neanderthal and sapiens coexisted in the same locations and there appears to have been a technological exchange, which strongly suggested cultural contact, where there is contact there will be sex.... there is no similar evidence for homo erectus... independent covergent/parallel evolution and still end up with genetically compatible speices is impossible.. there are no races....
So how can you contribute to a discussion about East Asian differences? Surely everytime someone uses the word 'Asian' (meaning East Asian) you should say 'there are no races', if that's what you believe. Why do you say 'there are no races' when you hear the word 'race'?
'Essentially' no different? Meaning...different? There is 'no evidence', therefore the consequent is true? You understand that's a fallacy? Do you say there are 'essentially no differences' (relative to what? amoebae? what differences?) based on evidence and facts and logic or based on a wishful thinking fantasy?
those look more likely to protect eyes from snow rather than light reflection . What "genetic split" ? Europeans and Asians belong to the same (small) branch of the African tree. East Asians lived either by the coast or next to big rivers , vitamin D can be found in abundance inside fish fat , Asians had no reason to turn white .
it exists as a social construct but there is no biological classification for race, we are a single species...
Have you ever hear of subspecies or further infrasubspecific classification? Are you a biologist? - - - Updated - - - This is politically correct garbage and Eurasians have significant quantities of unique alleles.
Protection from light, UV reflecting from snow can be very intense...Snow Blindness-cornea damage from uv rays can cause temporary or permanent blindness...
meaning we are the same, any differences biologically/genetically are insignificant, we are same species
there is no taxalogical classification for "east asian" "african" or any other regional/ethnic group...just a single species Homo Sapiens Sapiens... - - - Updated - - - ya I know, I've seen it before...
This is false. Homo Sapiens is a species , Homo Sapiens Sapiens is a subspecies, and has further infrasubspecific divisions. The politically correct mantras you parrot betray a total ignorance of biology.
I already know where this going and i have no interest in playing your game to expound your idiotic racist agenda....bye bye...
That's what happens when one mixes political faith and science. Lord preserve us from Liberals If we call "them", populations, instead of race, would that be acceptable to the on Board ? Sub Saharans lack an active immune gene the rest of us have. Often an extra leg muscle too. They are a different population, if not race Si? And that population of persons with flatter cheek bones around Asia do not metabolize Alcohol as well as others, exhibit dry powdery ear wax, not wet. And some of the men can't grow beards. A different population? And than there is those of us with football shaped craniums who really, really smell if we don't shower. Maybe we should speak of breeds, like dogs. And mutts too Moi Lord, protect me from Liberals. No
population, ethnic group...anything but race... Missing a body parts is normal in every population, my brother is missing a vertebrae is he different?...Mrs wyly was born two teeth less than normal is she different?...one of my kids has two more teeth than normal is she different as well?...my mother was born with 9 1/2 fingers, I knew someone born with 2 thumbs and six fingers, people born with 12 fingers is not uncommon...yet they're all within normal morphological range for the species... And dogs like humans are all the same a single species, breeds are nothing but forced incestous breeding...
