“…It is a social mechanism in which the culture's technological knowledge, behavior patterns, and cosmological beliefs are communicated and acquired (Hewlett & Cavalli-Sforza 1986). Knowledge transmission is conducted through everyday practices, such as learning by doing, helping adults with daily tasks, participating, observing and copying adults, interacting with the natural environment within a cultural context, developing abilities required for practical actions (Wyndham 2010;Zarger 2011), and by oral transmission (Berkes et al 2000).
