"Humans not descended from promiscuous primates"

 Charles Nunn, a University of Virginia biology researcher who led the study,
 published in the latest issue of the journal Science, reveals that monkeys
 are divided into promiscuous or monogamous characters.

 And the reaction to promiscuity has been an increase in the immune system
 defenses of the promiscuous monkeys.

 This because their promiscuity exposes them to more  disease infection
 opportunities. So those promiscuous monkeys have more white blood cells 

 The non-promiscuous or monogamous group of monkeys have a characteristic
 low white blood cell count. We humans belong in that monogamous group.

 `"Humans have white blood cell counts similar to those in primarily
 monogamous species" the researchers said.'

 Human behavior changes the number of strains of infectious diseases

 Simple models predict that only one strain of an infectious disease can
 exist at one time, but observation suggests otherwise. In a study in the
 August issue of The American Naturalist, Ken Eames and Matt Keeling
 (University of Warwick) use a mathematical model to help explain multiple
 strains, showing that the way humans interact is all-important.

 The researchers found that the coexistence of multiple infectious disease
 strains result from monogamous populations.

 "When people are serially monogamous (that is, interactions take place one
 at a time), groups with different behavior favor strains with different
 properties," explain the authors. "When new interactions occur frequently,
 rapidly transmitted strains are most successful, but when new interactions
 take place infrequently there is extra pressure on strains to have a long
 infectious period."
