A new theory of mind that includes nonhuman and artificial intelligences.
 
The much-lauded superiority of human intelligence has not prevented us from driving the planet into ecological disaster. For N. Katherine Hayles, the climate crisis demands that we rethink basic assumptions about human and nonhuman intelligences. In Bacteria to AI, Hayles develops a new theory of mind—what she calls an integrated cognitive framework (ICF)—that includes the meaning-making practices of lifeforms from bacteria to plants, animals, humans, and some forms of artificial intelligence. Through a sweeping survey of evolutionary biology, computer science, and contemporary literature, Hayles insists that another way of life, with ICF at its core, is not only possible but necessary to safeguard our planet’s future

Since Darwin, people have speculated about the evolutionary relationships among dissimilar species, including our connections to the diverse life forms known as microbes. In the 1970s biologists discovered a way to establish these kinships. This new era of exploration began with Linus Pauling’s finding that every protein in every cell contains a huge reservoir of evolutionary history. His discovery opened a research path that has changed the way biologists and others think about the living world. In Kin John L. Ingraham tells the story of these remarkable breakthroughs. His original, accessible history explains how we came to understand our microbe inheritance and the relatedness of all organisms on Earth.

Among the most revolutionary scientific achievements was Carl Woese’s discovery that a large group of organisms previously lumped together with bacteria were in fact a totally distinct form of life, now called the archaea. But the crowning accomplishment has been to construct the Tree of Life—an evolutionary project Darwin dreamed about over a century ago. Today, we know that the Tree’s three main stems are dominated by microbes. The nonmicrobes—plants and animals, including humans—constitute only a small upper branch in one stem.

Knowing the Tree’s structure has given biologists the ability to characterize the complex array of microbial populations that live in us and on us, and investigate how they contribute to health and disease. This knowledge also moves us closer to answering the tantalizing question of how the Tree of Life began, over 3.5 billion years ago.
