Nice hypothesis, but not exactly backed up by history. So many different societies have made so many diverse contributions to innovation, I'd be pretty amazed if you could draw a cohesive line through all (or most) of them.
Also, separately, it's pretty difficult to separate "bloodlines", which I assume you mean genetically inherited traits, with socially inherited traits.
A great physicist is probably more likely than average to have offspring that are also great physicists. But is that because of their "blood" (i.e. DNA) or because the children grew up in a household exposed to physics at a much higher degree than average. The children's "blood" is an inherited DNA trait, but their upbringing is an inherited social trait.
The question boils down to the age-old nature vs. nurture argument. All signs seem to point to nurture being the far more powerful influence.
