Mammalian vocal duets and turn-taking exchanges — long, coordinated acoustic signals exchanged between two individuals— are primarily found in family-living, pair-bonded mammals with a socially monogamous lifestyle (some rodents, some lemurs, tarsiers, titi monkeys, a Mentawai langur, gibbons and siamangs). Duetting and turn-taking patterns combine visual, chemical, tactile and auditory cues to produce some of the most exuberant displays in the realm of animal communication. How and why such phenotypes evolved independently across main lineages are fundamental questions at the core of the nature-nurture debate. Duetting styles ranging from antiphonal (non-overlapping) to simultaneous (overlapping) emissions have now been documented in various taxa, some of which are quite reminiscent of turn-taking rules in human conversation. Nonetheless, much remains to be learned about this complex motor skill, and at all four levels of analysis, namely (1) developmental processes, (2) causal mechanisms (3) functional properties and (4) evolutionary history. Given the strong link between this form of coordinated singing and pair-bonding, gaining a deeper understanding of this kind of cooperative behavior will likely shed more light on the deep evolutionary roots of human culture, language and music.

Stone tools are the most durable and common type of archaeological remain and one of the most important sources of information about behaviors of early hominins. Stone Tools and the Evolution of Human Cognition develops methods for examining questions of cognition, demonstrating the progression of mental capabilities from early hominins to modern humans through the archaeological record. Dating as far back as 2.5-2.7 million years ago, stone tools were used in cutting up animals, woodworking, and preparing vegetable matter. Today, lithic remains give archaeologists insight into the forethought, planning, and enhanced working memory of our early ancestors. Contributors focus on multiple ways in which archaeologists can investigate the relationship between tools and the evolving human mind-including joint attention, pattern recognition, memory usage, and the emergence of language. Offering a wide range of approaches and diversity of place and time, the chapters address issues such as skill, social learning, technique, language, and cognition based on lithic technology. Stone Tools and the Evolution of Human Cognition will be of interest to Paleolithic archaeologists and paleoanthropologists interested in stone tool technology and cognitive evolution.

Recent neuroscience research makes it clear that human biology is cultural biology - we develop and live our lives in socially constructed worlds that vary widely in their structure values, and institutions. This integrative volume brings together interdisciplinary perspectives from the human, social, and biological sciences to explore culture, mind, and brain interactions and their impact on personal and societal issues. Contributors provide a fresh look at emerging concepts, models, and applications of the co-constitution of culture, mind, and brain. Chapters survey the latest theoretical and methodological insights alongside the challenges in this area, and describe how these new ideas are being applied in the sciences, humanities, arts, mental health, and everyday life. Readers will gain new appreciation of the ways in which our unique biology and cultural diversity shape behavior and experience, and our ongoing adaptation to a constantly changing world.
