'human systems From an individual's perspective'

'...the scope of human systems from an individual's perspective is massive.  Historically, one may look to human origins at what has thought to be approximately 200,000 years ago in East Africa, around what is now Ethiopia (although now researchers are also looking toward Morocco at the 300,000+ year mark [Hublin et al. 2017; Richter et al. 2017]).  One may run through the long history of hunter-gatherer societies to the rise of agriculture and large state societies such as at Monte Alban in Oaxaca, Mexico, or at Chaco Canyon in what is now New Mexico.  One may carry this history forward to the rise of modern science, transnational economies, and the "information age."  Today (or at any point in history) one may also span the globe to take in the full scope of human systems, from what today is Canada and then to Mali, to Bangladesh, and back again.  Or to anyplace you might search on Google Earth.  We live in an era of the "glocal": a mash-up of the powerful reach of globalization with the idiosyncratic particularities of each of our localities.'
