what allows human beings to adapt to diverse physical environments?
Technology and higher intelligence enables human beings to adapt to diverse physical environments. Human beings inhabit environments as diverse as cold regions of Antarctica to extremely hot deserts of Africa and pleasant beaches of Pacific islands to mountains of Himalaya. Physically our body cannot handle the extreme environment and its detrimental effects on body. We use our higher intelligence to develop equipment to help us survive in adverse environmental conditions. An example is warm clothing and heating (electric) that we use to survive in very cold weather. We can also preserve and store food and transport packaged food and human beings practically anywhere we want. For living in hot weather, we have devised air conditioning, refrigeration and construction material and clothes to keep us cool and help us survive. This is how human beings have been able to survive in extremely adverse physical environments.
Hope this helps.
