The question of how the social becomes biological is, in one sense, about linking social effects with biological causes. Those causes are now more accessible than ever, thanks to new tools that researchers use to get under the hood in biology. But are we really connecting cause with effect? A close look at this research reveals a giant gap in our understanding of the relationship between molecular and human behavior. It's a gap that we will rarely bridge.</p><p>At first glance, you would think we have ample reason to be optimistic.

This year's Ebola crisis is probably just a dress rehearsal: Though the virus has killed at least 1,420 people in Africa in the last five months, Ebola is transmitted only through intimate contact with bodily fluids and doesn't have the global reach of a true pandemic, such as Spanish influenza in 1918. Humanity had no prior exposure or immunity to the Spanish flu, which is believed to have incubated in birds and pigs.
