I don't have time to talk to you. I'm as busy as a beaver. When the tourist season starts, this store is busy as Grand Central Station. Sorry I can't go to lunch with you. I'm as busy as a beaver building a new dam.
The expression adaptive strategies is used by anthropologist Yehudi Cohen to describe a societyâs system of economic production. Cohen argued that the most important reason for similarities between two (or more) unrelated societies is their possession of a similar adaptive strategy.In other words, similar economic causes have similar sociocultural effects.astoralists live in North Africa, the Middle East, Europe, Asia, and sub-Saharan Africa. These herders are people whose activities focus on such domesticated animals such as cattle, sheep, goats, camels, yak, and reindeer.
The functional definition allows us to identify adaptive traits, while the historical definition allows us to identify adaptations. Adaptive traits are those that increase the fitness of an organism [in a given environment]. Adaptations are adaptive traits that got selected for and remained. To understand the difference: vestigial organs are adaptations, but they are no longer adaptive. In other words, they were adaptive at one point and got selected for, therefore they are adaptations.
