Promiscuity Alters DNA and Boosts Immunity In Mice 91

An anonymous reader writes "Scientists from the University of California, Berkeley found that promiscuous mice have significantly stronger immune systems than monogamous mice, suggesting that promiscuous mice may have developed more robust immunity to protect them against the disease-causing bacteria they are exposed to from mating with multiple partners."

    "Promiscuity Alters DNA" makes it sound like promiscuity directly causes mutations. It seems, rather, that it results in greater variation in vaginal bacteria, a state which creates selective pressure favouring increased diversity in genes involved in the functioning of the immune system... which isn't quite the same thing.
