Haplogroup
R1b /
R1a
50% of North indian men have direct Indo-european ancestry, same thing goes for Iran and Pakistan and other 'Aryan' descended peoples.
Proto-indo-european religions/cultures share many common elements that can lead a people to greatness.
Italic (Roman empire), Celtic (British/America/USA), Slavic (USSR), Germanic (German Empire/British Empire/USA), Hellenic (Greeks in their many eras), Hindus (Indus-valley civilization).
A study was also undertaken on Pakistani boys in 2009. Young male children, who belonged to haplogroups R1a or R2, showed more signs of aggression and dominance as children than did young pakistanis of other haplgroups (mainly to hg G, H, J2, and L).
The logic behind testing children is that adults have learned to exhibit more acceptable behaviour due to education and cultural controls. Being aggressive does not just mean being prone to violent behaviour, but also being verbally aggressive, argumentative, uncooperative, stubborn/obstinate, and having a generally more competitive attitude towards others.
Razib Khan and Zack Ajmal both belong to haplogroup R1a.
