So if your bladder is twice as big as mine does that mean you win the pissing contest?
Hahahah! That's quote of the thread.
I think Seminole raised some interesting points, and as is the case with usual intelligence level to comprehend the content and context on gupshup, most of the people did fail to see what he was talking about. I've yet to see someone take a shot at his "Why black people lagged" question instead of picking out words at their face value to prove "my bladder is bigger than yours". ch*****y.
There is great division among theorists even in the field of scientific discovery to come to any solid conclusion regarding racial difference attributed towards advancement of a certain race. It comes down to subjective opinion in the end.
It's regression of things. Not one single factor is more predominantly deterministic than the other. There are physical factors as well as intangible ones. For example, in the case of "whites" in the west, few turns in the modern history along with opportunities present in the physical environment (geography, resourceful land, weather etc) contributed more to their advancement than the sheer skin color or height or musclular capabilities (We pick apples from the tree no more -- we can well capably stare at the apple now and have it fall on the earth as did Newton once). Industrial revolution, Renaissance, colonialism etc are some of the major forces behind such advancements.
Now point to note: The fact that white race somewhere else than the west also advanced does not blankly put racial advantages up on the conclusive measure (The question posed by TomSawyer itself is sort of falls into that category). The causes behind on geographical racial advancement in one case may be different than the other. There is a certain seperation of cause and effect here.
The other physicality to consider as a predominant factor is the time and space dimension strictly in terms of scientific discoveries to bolster the phenomenon like Renaissance. As it goes, certain scientific discoveries or inventions turn out to be the bolstering force to speed up more advanced achievments than the others. For example, discovery to produce electricity made so many other things possible at a greater speed than the invention of, say, wheel which didn't propagate much else in terms transportation. If electricity or steam engine wasn't there, wheel would still be, well, wheel. So, to put it very simply and oversimply, steam engine was a great force behind industrial revolution, which was a great force behind colonialism, which was a great force behind African people not being able to catch up quickly (whatcha gonna do when they come for you!). Africans may have or may have not advanced on their own if left alone but we'd never know that, or would we.
Colonialism in fact was a pretty big factor in intefering with advancement of other societies (read races), who, if given a chance (time and space factor again) may have succeeded to adopted pragmatic thought propagated by Renaissance. Just because Colonialism did introduce technologies to its colonies does not mean it makes up for the supperession it pulled off at the subservient population.
