Annalee Newitz February 29, 2016 Modern humans are building megacities – and networks of megacities – at an unprecedented scale. Annalee Newitz compares today’s urbanization phenomenon to that of the Neolithic period roughly 9,000 years ago, when humans first began living in sedentary communities. That shift prompted massive social, biological, and technological changes, creating the first “domesticated” humans. Using history as a guide, Newitz explores the evolutionary upheaval that modern humans may have set in motion, and what it might mean for us as a civilization. Annalee Newitz is the technology culture editor at Ars Technica. She holds a PhD in English and American Studies from UC Berkeley. Her most recent book is "Scatter, Adapt, and Remember: How Humans Will Survive a Mass Extinction".
