This book-really an essay-is the culmination of forty-five years of thinking as a psychiatrist about the relationship between severe mental illnesses and human evolution. I realized that the evolution of upright posture, large molar teeth, opposable thumbs, and large brains were all cumulative responses to a decisive shift in what MOTIVATED early humans compared to apes. I describe in vivid detail how the inner experience of major depression, panic disorder, schizophrenia, and bipolar disorder can be interpreted as emotional fossils that illustrate the ape-hominid evolutionary transformation in the mind. This understanding of how our motivations evolved not only allows you to make sense of hominid fossil finds, now with DNA, but offers a simple empathetic understanding of how self-awareness and language work.Although short and explicitly written to be accessible, this essay offers a post-Darwinian world view that is fundamentally optimistic and progressive.

This book describes the process through which fossils are created, and what we can learn from them.

Walk in the footsteps of the first fossil researchers to discover the earliest animal life on Earth. Explore whether dinosaurs had scales, fur, or feathers. Find out how fish learned to walk. This lively history combines storytelling with science to bring to life incredible creatures that once walked the Earth--the hallucigenia (a creature without tail or head), the tiktaalik (a walking fish), the plesiosaur (a peaceful sea dragon), and many more. Told with illustrations, comics, and facts, it shows how fossils tell a fascinating story about our oldest known species and how scientific thinking evolves.

In the history of life on this planet, 99.9 percent of all species have gone extinct. But a few have survived almost unchanged. Author Rebecca E. Hirsch introduces readers to six living fossils, including the chambered nautilus, the horseshoe crab with its sticky blue blood, and venomous platypuses that sting, as well as a comprehensive explanation of evolution and extinction for readers who may not be familiar with the terms yet. Readers will also discover a a spectacular timeline of the history of animal life on Earth. Dive into the stories of these incredible animals and find out how they help scientists piece together evolutionary history.

Describes fossils, how they were made, and what qualifies as a fossil.

Poetic Conventions as Cognitive Fossils offers a major theoretical statement of where poetic conventions come from. The work comprises Reuven Tsur's research in cognitive poetics to show how conventional poetic styles originate from cognitive rather than cultural principles. The book contrasts two approaches to cultural conventions in general, and poetic conventions in particular. They include what may be called the "culture-begets-culture" or "influence-hunting" approach, and the "constraints-seeking" or "cognitive-fossils" approach here expounded. The former assumes that one may account for cultural programs by pointing out their roots in earlier cultural phenomena and provide a map of their migrations. The latter assumes that cultural programs originate in cognitive solutions to adaptation problems that have acquired the status of established practice. Both conceptions assume "repeated social transmission," but with very different implications. The former frequently ends in infinite regress; the latter assumes that in the process of repeated social transmission, cultural programs come to take forms which have a good fit to the natural constraints and capacities of the human brain. Tsur extends the principles of this analysis of cognitive origins of poetic form to the writing systems, not only of the Western world, but also to Egyptian hieroglyphs through the evolution of alphabetic writing via old Semitic writing, and Chinese and Japanese writings; to aspects of figuration in medieval and Renaissance love poetry in English and French; to the metaphysical conceit; to theories of poetic translation; to the contemporary theory of metaphor; and to slips of the tongue and the tip-of-the-tongue phenomenon, showing the workings and disruption of psycholinguistic mechanisms. Analysis extends to such varying sources as the formulae of some Mediaeval Hebrew mystic poems, and the ballad 'Edward,' illustrative of extreme 'fossilization' and the constraints of the human brain.

Relates the competition between Othniel Marsh and Edward Cope to discover more fossils, name more species, and publish more papers that brought out the best and worst in them and provided the world with a new view of life on Earth.
