    1. Evidence [28] and theory [29] support the assertion that cultural evolution is more rapid than genetic evolution [27,28,30,31], even when measured on comparable scales [30,31]. One simple reason for this difference is that the ‘generation time’, G, of cultural transmission can be orders of magnitude shorter than that of genetic transmission [30]. In humans, the average time between the birth of parents and the birth of their offspring, genetic G, ranges from roughly 2 to 3 decades, while cultural G, the average time between learning a piece of information and transmitting it, ranges from seconds to decades. Thus, it is reasonable to presume that cultural inheritance may provide greater adaptive capacity than genetic inheritance.

      !- definition : Generation time - generation time of genetic transmission in range of 2 to 3 decades while for cultural transmission can vary from seconds to decades.
