Many of the traditions which we think of as very ancient in their origins were not in fact sanctioned by long usage over the centuries, but were invented comparatively recently. This book explores ...examples of this process of invention – the creation of Welsh and Scottish 'national culture'; the elaboration of British royal rituals in the nineteenth and twentieth centuries; the origins of imperial rituals in British India and Africa; and the attempts by radical movements to develop counter-traditions of their own. It addresses the complex interaction of past and present, bringing together historians and anthropologists in a fascinating study of ritual and symbolism which poses new questions for the understanding of our history.
In this book, Kate Distin proposes a theory of cultural evolution and shows how it can help us to understand the origin and development of human culture. Distin introduces the concept that humans ...share information not only in natural languages, which are spoken or signed, but also in artefactual languages like writing and musical notation, which use media that are made by humans. Languages enable humans to receive and transmit variations in cultural information and resources. In this way, they provide the mechanism for cultural evolution. The human capacity for metarepresentation - thinking about how we think - accelerates cultural evolution, because it frees cultural information from the conceptual limitations of each individual language. Distin shows how the concept of cultural evolution outlined in this book can help us to understand the complexity and diversity of human culture, relating her theory to a range of subjects including economics, linguistics, and developmental biology.
In this study Clive Gamble presents and questions two of the most famous descriptions of change in prehistory. The first is the 'human revolution', when evidence for art, music, religion and language ...first appears. The second is the economic and social revolution of the Neolithic period. Gamble identifies the historical agendas behind 'origins research' and presents a bold alternative to these established frameworks, relating the study of change to the material basis of human identity. He examines, through artefact proxies, how changing identities can be understood using embodied material metaphors and in two major case-studies charts the prehistory of innovations, asking, did agriculture really change the social world? This is an important and challenging book that will be essential reading for every student and scholar of prehistory.

Our ability to walk on two legs is not only a characteristic human trait but one of the things that made us human in the first place. Once our ancestors could walk on two legs, they began to do many ...of the things that apes cannot do: cross wide open spaces, manipulate complex tools, communicate with new signal systems, and light fires. Titled after the last two words of Darwin's Descent of Man and written by a leading scholar of human evolution, Lowly Origin is the first book to explain the sources and consequences of bipedalism to a broad audience. Along the way, it accounts for recent fossil discoveries that show us a still incomplete but much bushier family tree than most of us learned about in school. Jonathan Kingdon uses the very latest findings from ecology, biogeography, and paleontology to build a new and up-to-date account of how four-legged apes became two-legged hominins. He describes what it took to get up onto two legs as well as the protracted consequences of that step--some of which led straight to modern humans and others to very different bipeds. This allows him to make sense of recently unearthed evidence suggesting that no fewer than twenty species of humans and hominins have lived and become extinct. Following the evolution of two-legged creatures from our earliest lowly forebears to the present, Kingdon concludes with future options for the last surviving biped. A major new narrative of human evolution, Lowly Origin is the best available account of what it meant--and what it means--to walk on two feet.
The origin recognition complex (ORC) is essential for initiation of eukaryotic chromosome replication as it loads the replicative helicase-the minichromosome maintenance (MCM) complex-at replication ...origins
. Replication origins display a stereotypic nucleosome organization with nucleosome depletion at ORC-binding sites and flanking arrays of regularly spaced nucleosomes
. However, how this nucleosome organization is established and whether this organization is required for replication remain unknown. Here, using genome-scale biochemical reconstitution with approximately 300 replication origins, we screened 17 purified chromatin factors from budding yeast and found that the ORC established nucleosome depletion over replication origins and flanking nucleosome arrays by orchestrating the chromatin remodellers INO80, ISW1a, ISW2 and Chd1. The functional importance of the nucleosome-organizing activity of the ORC was demonstrated by orc1 mutations that maintained classical MCM-loader activity but abrogated the array-generation activity of ORC. These mutations impaired replication through chromatin in vitro and were lethal in vivo. Our results establish that ORC, in addition to its canonical role as the MCM loader, has a second crucial function as a master regulator of nucleosome organization at the replication origin, a crucial prerequisite for efficient chromosome replication.

Language, more than anything else, is what makes us human. It appears that no communication system of equivalent power exists elsewhere in the animal kingdom. Any normal human child will learn a ...language based on rather sparse data in the surrounding world, while even the brightest chimpanzee, exposed to the same environment, will not. Why not? How, and why, did language evolve in our species and not in others? Since Darwin's theory of evolution, questions about the origin of language have generated a rapidly-growing scientific literature, stretched across a number of disciplines, much of it directed at specialist audiences. The diversity of perspectives - from linguistics, anthropology, speech science, genetics, neuroscience and evolutionary biology - can be bewildering. Tecumseh Fitch cuts through this vast literature, bringing together its most important insights to explore one of the biggest unsolved puzzles of human history.

"History as it should be written."-Barry Cunliffe,
Guardian "Scott hits the nail squarely on
the head by exposing the staggering price our ancestors paid for
...civilization and political order."-Walter Scheidel, Financial
Times Why did humans abandon hunting and gathering
for sedentary communities dependent on livestock and cereal grains,
and governed by precursors of today's states? Most people believe
that plant and animal domestication allowed humans, finally, to
settle down and form agricultural villages, towns, and states,
which made possible civilization, law, public order, and a
presumably secure way of living. But archaeological and historical
evidence challenges this narrative. The first agrarian states, says
James C. Scott, were born of accumulations of domestications: first
fire, then plants, livestock, subjects of the state, captives, and
finally women in the patriarchal family-all of which can be viewed
as a way of gaining control over reproduction. Scott explores why
we avoided sedentism and plow agriculture, the advantages of mobile
subsistence, the unforeseeable disease epidemics arising from
crowding plants, animals, and grain, and why all early states are
based on millets and cereal grains and unfree labor. He also
discusses the "barbarians" who long evaded state control, as a way
of understanding continuing tension between states and nonsubject
peoples.
The six-subunit origin recognition complex (ORC) binds to DNA to mark the site for the initiation of replication in eukaryotes. Here we report a 3 Å cryo-electron microscopy structure of the ...Saccharomyces cerevisiae ORC bound to a 72-base-pair origin DNA sequence that contains the ARS consensus sequence (ACS) and the B1 element. The ORC encircles DNA through extensive interactions with both phosphate backbone and bases, and bends DNA at the ACS and B1 sites. Specific recognition of thymine residues in the ACS is carried out by a conserved basic amino acid motif of Orc1 in the minor groove, and by a species-specific helical insertion motif of Orc4 in the major groove. Moreover, similar insertions into major and minor grooves are also embedded in the B1 site by basic patch motifs from Orc2 and Orc5, respectively, to contact bases and to bend DNA. This work pinpoints a conserved role of ORC in modulating DNA structure to facilitate origin selection and helicase loading in eukaryotes.
