A tendency for similar individuals to cooperate selectively with one another, even if they are not close relatives, can evolve spontaneously in simple organisms....
AUSTIN, Texas -- A biologist at The University of Texas at Austin has presented a new theory that sheds light on how organisms, including viruses like HIV, rapidly evolve in the face of vaccines and antibiotics. Dr. Lauren Ancel Meyers says the new model could help identify genes that increase a pathogen's ability to evolve quickly against immune responses. Knowing those genes could help scientists develop new and better vaccines. Meyers' model predicts that populations can evolve "genetic...
