Convergent Evolution in Stone-Tool Technology
Scholars from a variety of disciplines consider cases of convergence in lithic technology, when functional or developmental constraints result in similar forms in independent lineages. Hominins began using stone tools at least 2.6 million years ago, perhaps even 3.4 million years ago.Given the nearly ubiquitous use of stone tools by humans and their ancestors, the study of lithic technology offers an important line of inquiry into questions of evolution and behavior.This book examines convergence in stone tool-making, cases in which functional or developmental constraints result in similar forms in independent lineages.Identifying examples of convergence, and distinguishing convergence from divergence, refutes hypotheses that suggest physical or cultural connection between far-flung prehistoric toolmakers.Employing phylogenetic analysis and stone-tool replication, the contributors show that similarity of tools can be caused by such common constraints as the fracture properties of stone or adaptive challenges rather than such unlikely phenomena as migration of toolmakers over an Arctic ice shelf.

The Cricket: Black Music in Evolution, 1968-69 : Black Music in Evolution, 1968-69
A rare document of the 1960s Black Arts Movement featuring Albert Ayler, Amiri Baraka, Milford Graves, Sun Ra, Cecil Taylor, and many more, The Cricket fostered critical and political dialogue for Black musicians and writers. Edited by poets and writers Amiri Baraka, A. B. Spellman, and Larry Neal between 1968 and 1969 and published by Baraka’s New Jersey–based Jihad productions shortly after the time of the Newark Riots, this experimental music magazine ran poetry, position papers, and gossip alongside concert and record reviews and essays on music and politics.Over four mimeographed issues, The Cricket laid out an anticommercial ideology and took aim at the conservative jazz press, providing a space for critics, poets, and journalists (including Stanley Crouch, Haki Madhubuti, Ishmael Reed, Sonia Sanchez and Keorapetse Kgositsile) and a range of musicians, from Mtume to Black Unity Trio, to devise new styles of music writing. The publication emerged from the heart of a political movement—“a proto-ideology, akin to but younger than the Garveyite movement and the separatism of Elijah Mohammed,” as Spellman writes in the book’s preface—and aimed to reunite advanced art with its community, “to provide Black Music with a powerful historical and critical tool” and to enable avant-garde Black musicians and writers “to finally make a way for themselves. ” This publication gathers all issues of the magazine with an introduction by poet and scholar David Grundy, who argues that The Cricket “attempted something that was in many ways entirely new: creating a form of music writing which united politics, poetry, and aesthetics as part of a broader movement for change; resisting the entire apparatus through which music is produced, received, appreciated, distributed, and written about in the Western world; going well beyond the tried-and-tested journalistic route of description, evaluation, and narration. ”David Grundy is the author of A Black Arts Poetry Machine: Amiri Baraka and the Umbra Poets (Bloomsbury Academic, 2019) and coeditor, with Lauri Scheyer, of Selected Poems of Calvin C. Hernton (Wesleyan University Press, forthcoming). He is currently a British Academy Fellow at the University of Warwick, United Kingdom, where he is working on two manuscripts, Survival Music: Free Jazz Then and Now and Never by Itself Alone: Queer Poetry in Boston and San Francisco, 1943–Present (Oxford University Press, forthcoming), and a further edited collection on Umbra. A. B. Spellman is a poet, music critic, and former director of the Arts in Education Study Project for the National Endowment of the Arts.

The Science of Music : How Technology has Shaped the Evolution of an Artform
Music is shaped by the science of sound. How can music - an artform - have anything to do with science?Yet there are myriad ways in which the two are intertwined, from the basics of music theory and the design of instruments to hi-fi systems and how the brain processes music. Science writer Andrew May traces the surprising connections between science and music, from the theory of sound waves to the way musicians use mathematical algorithms to create music. The most obvious impact of science on music can be seen in the way electronic technology has revolutionised how we create, record and listen to music.Technology has also provided new insights into the effects that different music has on the brain, to the extent that some algorithms can now predict our reactions with uncanny accuracy, which raises a worrying question: how long will it be before AI can create music on a par with humans?

What is cosmic evolution, chemical evolution, biological evolution, and cultural evolution?
Cosmic evolution refers to the development and changes in the universe over time, including the formation of galaxies, stars, and planets. Chemical evolution is the process by which elements and compounds have changed and evolved over time, leading to the formation of complex molecules and the conditions necessary for life. Biological evolution is the process by which living organisms have changed and diversified over time through genetic variation, natural selection, and other mechanisms. Cultural evolution refers to the development and changes in human societies, including the growth of technology, language, art, and social structures.
-
What triggers evolution?
Evolution is triggered by a combination of factors, including genetic mutations, natural selection, genetic drift, and gene flow. Genetic mutations create new variations in a population, which can then be acted upon by natural selection, where individuals with advantageous traits are more likely to survive and reproduce. Genetic drift and gene flow also play a role in shaping the genetic makeup of a population over time. These factors collectively drive the process of evolution by leading to changes in the frequency of genetic traits within a population.
-
Is evolution stingy?
Evolution is not inherently stingy, but rather it is driven by the process of natural selection, which favors traits that increase an organism's chances of survival and reproduction. This can sometimes result in the appearance of stinginess, as resources are allocated to the most advantageous traits. However, evolution also promotes cooperation and mutualism in many species, leading to the development of symbiotic relationships and social behaviors that benefit the group as a whole. Overall, evolution is a complex process that can result in both competitive and cooperative behaviors, depending on the specific ecological and environmental pressures at play.
-
What about evolution?
Evolution is the process by which species of organisms change over time through the process of natural selection, genetic drift, and other mechanisms. It is a fundamental concept in biology and has been supported by a large body of evidence from fields such as genetics, paleontology, and comparative anatomy. Evolution explains the diversity of life on Earth and how species have adapted to their environments over millions of years. It is a well-established scientific theory that has withstood rigorous testing and continues to be a central principle in the study of biology.

Can evolution stop?
Evolution is a continuous process driven by genetic variation, natural selection, and environmental changes. While it is theoretically possible for evolution to slow down or even temporarily stop in a stable environment with little genetic variation, it is unlikely to completely halt. As long as there are factors such as mutations, genetic recombination, and environmental pressures, evolution will continue to shape and change species over time. Therefore, while it may slow down under certain conditions, it is unlikely for evolution to completely stop.
-
Will evolution change?
Evolution is a continuous process driven by genetic variation, natural selection, and environmental changes. As long as these factors continue to operate, evolution will continue to occur. However, the specific direction and pace of evolution may change in response to new environmental pressures, genetic mutations, and other factors. Therefore, while the fundamental process of evolution is unlikely to change, the specific outcomes and patterns of evolution may vary over time.
-
What is the difference between synthetic evolution and natural evolution?
Synthetic evolution involves the intentional manipulation of genetic material by humans in a controlled environment, such as in a laboratory setting, to produce desired traits or outcomes. In contrast, natural evolution occurs in nature through the process of natural selection, where organisms with advantageous traits are more likely to survive and reproduce, leading to changes in the genetic makeup of a population over time. While synthetic evolution is directed and guided by human intervention, natural evolution is driven by environmental pressures and random genetic mutations.
-
Is evolution really proven?
Yes, evolution is a well-established scientific theory that is supported by a vast amount of evidence from various fields such as genetics, paleontology, and comparative anatomy. The theory of evolution explains the diversity of life on Earth and how species have changed over time through natural selection and other mechanisms. While there may still be gaps in our understanding of certain aspects of evolution, the overall evidence strongly supports the theory as a fundamental principle of biology.
