摘要
Pathogens can spread 流行病學cally through 族群s. Beneficial contagions, such as 病毒es that enhance host survival or technological innovations that improve quality of life, also have the potential to spread 流行病學cally. How do the dynamics of beneficial 生物 and 社會 流行病學cs differ from those of detrimental 流行病學cs? We investigate this question using three theoretical approaches as well as an empirical analysis of concept propagation. First, in 演化ary models, we show that a beneficial horizontally-transmissible element, such as viral DNA, spreads super-exponentially through a 族群, substantially more quickly than a beneficial 突變. Second, in an 流行病學ological 社會 網絡 approach we show that infections that cause increased connectivity lead to faster-than-exponential _fixation in the 族群. Third, in a sociological mo
