  • Kostas Kampourakis, "Ancestry Reimagined: Dismantling the Myth of Genetic Ethnicities" (Oxford UP, 2023)

    Kostas Kampourakis, "Ancestry Reimagined: Dismantling the Myth of Genetic Ethnicities" (Oxford UP, 2023)
    Oct 27 2024
    Recent social and political psychological research indicates that increased access to ancestry testing has strengthened the notion of genetic essentialism among some groups, or the idea that our biology ties us to particular ethnic identities. This can boost a sense of cultural pride and prosocial behaviors among communities that are perceived to be similar. In the worst-case scenarios, however, this phenomenon can contribute to deeper social woes like misinformation, anti-science agendas, and even social hatred among those who believe in racial superiority. Using research from both the social sciences and the genetics literature as support, Ancestry Reimagined: Dismantling the Myth of Genetic Ethnicities (Oxford University Press, 2023) establishes realistic expectations about what we can learn from our DNA as a foundation for examining the psychological impact of ancestry testing, including the differences between how this information is perceived versus its reality. With this book, Dr. Kampourakis flexes his muscles as an esteemed interdisciplinary science educator and author to challenge these traditional social constructs, using the current genetic testing science as a myth busting tool. Kampourakis argues that DNA ancestry testing cannot reveal a person's true ethnic identity because ethnic groups are socially and culturally constructed. In 10 accessible chapters, he explains the assumptions underlying the scientific study of ancestry, and the resulting paradoxes that are often overlooked. What the study of human DNA mostly shows is that human DNA variation is continuous, and it is not possible to clearly delimit ethnic groups based on DNA data. As a result, we all are members of a huge, extended family, and not of genetically distinct ethnic groups. What ancestry tests can provide are probabilistic estimations of similarities between the test-takers and particular reference populations. This does not devalue the results of these tests, however, because they can indeed provide some valuable information to people who may not know much about their ancestors. In fact, what the tests are very good at doing is finding close relatives, and this is perhaps why the whole enterprise should be rebranded as family, not ancestry, testing. Ultimately, this book reveals that genetic essentialism, biological ethnic identities, racial superiority, and similar social constructs are scientifically unsupported Kostas Kampourakis is the author and editor of several books about evolution, genetics, philosophy and history of science, as well as the editor of the Cambridge University Press book series Understanding Life. He teaches biology and science education courses at the University of Geneva Morteza Hajizadeh is a Ph.D. graduate in English from the University of Auckland in New Zealand.

  • Francisco Aboitiz, "A History of Bodies, Brains, and Minds: The Evolution of Life and Consciousness" (MIT Press, 2024)

    Francisco Aboitiz, "A History of Bodies, Brains, and Minds: The Evolution of Life and Consciousness" (MIT Press, 2024)
    Oct 19 2024
    Francisco Aboitiz is a professor at the Medical School and the director of the Interdisciplinary Center for Neuroscience at Pontificia Universidad Católica de Chile. A History of Bodies, Brains, and Minds: The Evolution of Life and Consciousness (MIT Press, 2024) tells the story of life and nervous systems. It introduces the conceptual framework and terminology of evolution, gives a great overview of our current knowledge and a thorough discussion of open questions. The first part defines two basic concepts: evolution and life. Surprisingly, we learn that the first definition is more straightforward. If you are challenged by some terminology in the later chapters - like phylogeny, ontogeny, or the different types of homology - it is highly recommended to revisit the definitions in the first chapter. The story begins in the second part. Chapter 3 introduces multiple theories on how the first cells might have appeared. In the next chapter, these cells start to form more complex, multicellular organisms. Chapter 5 is dedicated to the main characteristics and early history of neurons. In the third part, we get acquinted with more complex animals. In chapter 6 with the bilaterians, in chapter 7 and 8 with the vertebrates and their nervous system, in chapter 9 with mammals. Chapter 10 provides a deep dive into the neocortex and its role in cognition. The fourth part of the book is about "a singular ape". Chapter 11 describes the history of primates, focusing on Hominins. It goes into details on various aspects like walking, the growth of brains, toolmaking, and social life. Chapter 12 describes the evolution of vocal communication. Chapter 13 discusses how speech has influenced communication and social life. Chapter 14 explores numerous open questions around consciousness. How to define it? When and how did it emerge in evolution? Which animals are conscious and in which ways? After this long history, chapter 15 arrives in the present and the future. What are some current evolutionary trends? How do cultural and technological changes influence our nervous systems? In our conversation with Professor Aboitiz, we focused on a few remarkable milestones in this story. For start, he outlined some theories how life might have begun. Then a huge jump in time followed: How the first mammals appeared and survived in a world dominated by dinosaurs. Professor Aboitiz elaborated on how the brains of mammals differ from the brains of other vertebrates. He described the cerebral cortex, a new part in the mammalian brain. The role of senses changed significantly: The early mammals had worse vision, but better smell, touch, and audition compared to other vertebrates. Changes in the anatomy of the head and neck supported these more developed senses. The enhanced olfactory system is also related to the hippocampus, where some new skills appeared: advanced spatial orientation and short-term memory. The next milestone we discussed in detail is the appearance of language. Professor Aboitiz shared some fascinating facts about the vocal communication of birds and primates. He explained the connection between toolmaking and language. He described the speech loop and the connection between working memory and talking. He proposes that manual gestures and vocal communication have evolved together, and communication has always been multi-modal. The last part of our conversation focused on the current and future situation. How culture and technology has changed our nervous system, e.g. how a brain area is particularly involved in reading. Professor Aboitiz also discussed the more recent technological innovations and their effects on society and the environment. He introduced the social projects conducted by the Interdisciplinary Center for Neuroscience. The project RIEN (Robótica Integral Educativa & Neurociencia) facilitates workshops where kids work in teams with rotating roles to build and program robots. Learn more about your ad choices.

  • Alan F. Blackwell, "Moral Codes: Designing Alternatives to AI" (MIT Press, 2024)

    Alan F. Blackwell, "Moral Codes: Designing Alternatives to AI" (MIT Press, 2024)
    Oct 6 2024
    Why the world needs less AI and better programming languages. Decades ago, we believed that robots and computers would take over all the boring jobs and drudgery, leaving humans to a life of leisure. This hasn’t happened. Instead, humans are still doing boring jobs, and even worse, AI researchers have built technology that is creative, self-aware, and emotional—doing the tasks humans were supposed to enjoy. How did we get here? In Moral Codes: Designing Alternatives to AI (MIT Press, 2024), Alan Blackwell argues that there is a fundamental flaw in the research agenda of AI. What humanity needs, Blackwell argues, is better ways to tell computers what we want them to do, with new and better programming languages: More Open Representations, Access to Learning, and Control Over Digital Expression, in other words, MORAL CODE. Blackwell draws on his deep experiences as a programming language designer—which he has been doing since 1983—to unpack fundamental principles of interaction design and explain their technical relationship to ideas of creativity and fairness. Taking aim at software that constrains our conversations with strict word counts or infantilizes human interaction with likes and emojis, Blackwell shows how to design software that is better—not more efficient or more profitable, but better for society and better for all people. Covering recent research and the latest smart tools, Blackwell offers rich design principles for a better kind of software—and a better kind of world. Alan F. Blackwell is Professor of Interdisciplinary Design in the Cambridge University department of Computer Science and Technology. He is a Fellow of Darwin College Cambridge, cofounder with David Good of the Crucible Network for Research in Interdisciplinary Design, and with David and Lara Allen the Global Challenges strategic research initiative of the University of Cambridge. Dr. Michael LaMagna is the Information Literacy Program & Library Services Coordinator and Professor of Library Services at Delaware County Community College. Learn more about your ad choices.
