Where did all this K haplotype get in Oceania and how did it also get in cameroon?
It seems very dispersed, where does it originate and what would be the best phene to represent how people carrying this haplotype looks?

My analysis is that the author(s) assumes that a low frequency of a specific hapolgroup indicates 'lesser' (my own words) and therefore not really important based on their location in Africa, Asia or Oceania but this is FALSE. I see the exact opposite. Gene flow, based on what I have seen or understood is from Africa to Middle East to Europe proper. That is the dominant pattern. Back migration has occured but the level and extent deserves further scrutiny. From the dominant gene flow, the K group left its African homeland (what we know today as Cameroon???) and took different paths, one to Oceania, another Fertile Crescent, another Asia then to Europe. As varying K groups met (as defined by their Euro homeland, and away from the main founder group, the frequencey of K had to increase because of the varying waves from a specific area so naturally its proliferation would be a clue. Just like in modern times, e.g. people from Sweden or Finland settling in Northern Illinois, Wiscosin or Minnesota due to word of mouth, familiarity (climate) and opportunity!
When you rework/reword the Wikipedia piece as it should be, here is an example.
REWORK In human genetics, Haplogroup K (M9) is a Human Y-chromosome DNA haplogroup.
It first appeared approximately 40,000 years ago among various populations of Eurasia, Oceania, and northern Africa and spread to Iran or southern Central Asia. Haplogroups K1, K2, K3, K4, K6, and K7 brought fruition to many assoprted groups within the region
Today, haplogroup K and its descendant haplogroups are the patrilineal ancestors of most of the people living in the Northern Hemisphere, including most Europeans, many Indians, and almost all Asians and Native Americans. Other lineages derived from Haplogroup K are found among Melanesian populations, indicating an ancient link between most Eurasians and some populations of Oceania.
This haplogroup is a descendant of Haplogroup F (M89). Its major descendant haplogroups are K5 (M230), L (M20), M (M4), NO (M214) (plus NO's descendants N and O), and P (M45) (plus P's descendants Q and R).
No data points were changed! If K5 is as important as it is claimed, shouldn't it be K1 But no! Just my thoughts in a free society.

Another thing you don't get is that lineages have nothing to do with phenotype. For all appearances a 'white' person could have recent African ancestry and vice versa-- a black person with European ancestry!

Never stated anything to do with your assumptions! It be as it be?!
