Caucasians, Native Americans and Polynesians are more likely to be type A, whereas Asians and Slavic (gypsies mostly) are more likely to be type B (making the rest of the world type O with 1% of the world populace being type AB). However, the only group who did not fall under any of these categories were in fact, the Welsh.
After being funded by the Peoples Study of the K.M.W University (my sister lent me a quarter) to conduct further research to detail my findings, I used these cold, hard facts to effectively deduce that since the Welsh people cannot be properly analyzed, they must be, due to deductive reasoning, be the genetically superior race. As such we must create a plan of action to interbreed with them and gain their genetically desirable traits. The clearest plan of action would be to divide them in half and breed them into the A and B groups.
Once this stage has been finalized, the world will have only two races, both of which will be super human demigods, having twice the strength of our human bodies and twice the intelligence of our mortal minds. This stage has been labeled "phase miscegenation" (not the official name, just something we are kicking around the office.) After this phase, all that is left is to breed the two demigod races into one, thus making us immortal, with endless strength and immune to all disease.
Once we are all one singular and eternal race, there will inevitably be world peace and social status will be a thing of the past. Man will work only to better himself and the idea of currency shall be a foreign one. (Just like in Star trek). However, due to the cessation of war on earth, we will have lost our battle skills and aliens shall inevitably attack us in the year 2008, destroying planet earth and ending our otherwise perfect race
