Evidence in nature:
Tawny wls, a type f reddish-brwn r grey Eurpean bird, actually cme in tw clurs. And in Finland, the freezing, snwy winters give pale grey birds a camuflage (保护色) advantage ver their darker brwn-feathered cunterparts (同类). But as the Finnish winters get milder, the grey wls are disappearing. The birds get their plumage (羽毛) clur frm their parents. The grey tawnys, being better hidden frm their enemies in the snw, seem t have ther genetic advantages that make them healthier and strnger. But despite this, the brwn wl ppulatin is nw larger than that f the greys, because the warmer winters have imprved the brwn wls’ chances f survival.
Evidence in sciety:
Between nw and the 21st century, cmpanies will perate in different ways. Peple will mve arund t d different jbs, rather than mving up in the cmpany as befre. Many mre peple will wrk fr small, dynamic cmpanies which can respnd quickly t changes in the market. Other peple will give up wrking fr a bss and start their wn business. All this means that cmpanies will require peple wh are flexible and can wrk n their wn. Because f this, wrkers will have t be mre flexible.
