The Biological Overview Effect: Our Place in Nature

open access: yesJournal of Big History, 2019
While gazing at the Earth from orbit, some astronauts have described a cognitive shift known as the overview effect. Here we describe an analogous biological overview effect produced by looking at the tiny twig of humanity on the tree of life.
