“They fingered the spots based on two theories on the distribution of biological species. One of them, the so-called distance-decay theory, states that the similarity and correlation between species at two locations decreases as the distance between them increases. As such, the geographers figure bin Laden can’t have gone far—he is believed to have fled Afghanistan’s Tora Bora region at the end of 2001—if he wished to remain on similar terrain in a familiar cultural environment.
“Island biogeography, the other tool in the team’s theoretical analysis, posits that large, closely spaced pockets of life (islands) support more species and are less ravaged by extinction than small, isolated islands. With cities standing in for islands, the researchers speculate that bin Laden would most likely hide out in a large town with minimal isolation, because even though there’s more risk of being spotted he would also have access to resources needed to stay alive as well as under cover.
“These theories, they say, point to Parachinar in Pakistan’s Federally Administered Tribal Areas.”

reductionism works (on a certain level) ’cause we are just busy little biological creatures running around like all the other busy little biological creatures.
