Examination of DNA from 21 primate species - from squirrel monkeys to humans - exposes an evolutionary war against infectious bacteria over iron that circulates in the host's bloodstream. Supported by experimental evidence, these findings, published in Science on Dec. 12, demonstrate the vital importance of an increasingly appreciated defensive strategy called nutritional immunity.
