Mutual Aid: The Other Law Of The Jungle. Gauthier Chapelle And Pablo Servigne. Cambridge, Polity Press. 2022. 310 Pp, Tom P. Flower Dr
Mutual Aid: The Other Law Of The Jungle. Gauthier Chapelle And Pablo Servigne. Cambridge, Polity Press. 2022. 310 Pp, Tom P. Flower Dr
Emancipations: A Journal of Critical Social Analysis
In 1902, the anarchist Peter Kropotkin published Mutual Aid in which he promoted a radical perspective on evolution in which cooperation, as well as selfishness, drive the form, diversification and organization of life on earth. Despite initial recognition, Kropotkin’s contributions have been largely forgotten, even as modern evolutionary theory has recognized the central role of cooperation. In Mutual Aid: the other law of the jungle, Pablo Servigne and Gauthier Chappelle restore Kropotkin’s insights to their rightful place as foundational for our understanding of evolution. They further seek to overturn the pernicious misconception of the 20th century, that nature is …
Ecology And Evolution Of Social Information Use, Clare T. M. Doherty
Ecology And Evolution Of Social Information Use, Clare T. M. Doherty
Dartmouth College Ph.D Dissertations
Sociality is a strategy many animals employ to cope with their environments, enabling them to survive and reproduce more successfully than would otherwise be possible. When navigating their environments and making decisions, social individuals often use information provided by conspecifics (in the form of social cues and signals), thereby increasing the scope and reliability of the information they can gather. However, social information use may be influenced by many factors, including key differences in context across the physical and social environment. My thesis asks and answers a series of questions regarding the trade-offs in social information use across different contexts, …
The Biological Influence Of Stories & The Importance Of Reading Fiction, Elise N. Good, Katharine Schaab
The Biological Influence Of Stories & The Importance Of Reading Fiction, Elise N. Good, Katharine Schaab
The Kennesaw Journal of Undergraduate Research
Fictional narratives and stories have persisted throughout human history. However, perhaps due to a bias that stories offered nothing more than entertainment for the reader or perhaps that they are not useful outside of the realm of academia, the research within science academia has been lacking in literature on why these narratives have endured. Unfortunately, due to the lack of conversation across disciplines, particularly those of science and literature, this subject has not been thoroughly investigated through an interdisciplinary lens. Within this paper, the goal is to analyze the benefits of fictional narratives through biological, evolutionary, and neuropsychological perspectives. Research …
Assessing The Utility Of The Pmm And Mmc Indices Among Extant Hominoid Genera, Julie A. Strain
Assessing The Utility Of The Pmm And Mmc Indices Among Extant Hominoid Genera, Julie A. Strain
Theses and Dissertations
This thesis set out to incorporate extant hominoid genera into an analysis of PMM and MMC to assess utility in phylogeny and predicting known taxonomic groups. Based on previous claims, we expect PMM/pmm and MMC/mmc to perform better than M1/m1 shape and size, our baseline for success, but they do not.
Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos
Factors Influencing Primate Hair Microbiome Diversity, Catherine Kitrinos
Masters Theses
Primate hair is both a substrate upon which essential social interactions occur and an important host-pathogen interface. As commensal microbes provide important immune functions for their hosts, understanding the microbial diversity in primate hair could provide insight into primate immunity and disease transmission. While studies of human hair and skin microbiomes show differences in microbial communities across body regions, little is known about the nonhuman primate hair microbiome. In this study, we collected hair samples (n=159) from 8 body regions across 12 nonhuman primate species housed at 3 US institutions to examine 1) the diversity and composition of the primate …
Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter
Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter
Intuition: The BYU Undergraduate Journal of Psychology
Darwin offered an evolutionary perspective on the origins of human morality, suggesting that humans share a biological foundation with nonhuman primates. This paper reviews the current literature on moral and prosocial behaviors of nonhuman primates, specifically examining whether nonhuman primates exhibit behaviors that are typical of empathy and fairness. The literature documents that nonhuman primates exhibit empathetic behaviors regarding emotional contagion and sympathetic concern. There is also evidence that nonhuman primates have a sense of fairness, seen in their reciprocal behaviors and aversion to inequity. Taken together, this suggests that there are evolutionary roots of morality, lending empirical support to …
The Phoenix, Fernanda Perez-Alvarez
The Phoenix, Fernanda Perez-Alvarez
Montserrat Annual Writing Prize
This article uses a mythical creature, the phoenix, to examine and illustrate the biological principles for generation of an adult body plan from a single cell. Using the study of developmental biology, it explores the cellular and molecular biology that underpins the massive complexity of creating an adult body plan. It also explores the similarities and differences between different embryos, and how nature and evolution have shaped the biology of those embryos to create different body plans.
The Evolution Of Technology, Kelly Cooper
The Evolution Of Technology, Kelly Cooper
Williams Honors College, Honors Research Projects
As per outlined by Dr. Quinn, this literature review will be a comprehensive review paper including an overview of current and previous research done in the field of Memetics. This will further include sifting through literature to hone in on a specific, new area of memetics Dr. Weeks is focused on, the evolutionary change of abiotic factors through purchasing. This is to be completed with the help of the library worshops designed to teach the skills necessary to undergo a literature review of this size. I will also participate in weekly reading groups to discuss papers and work closely with …
De-Coding The Impact Of Evolved Changes In Gene Expression And Cellular Phenotype On Primate Evolution, Trisha Zintel
De-Coding The Impact Of Evolved Changes In Gene Expression And Cellular Phenotype On Primate Evolution, Trisha Zintel
Doctoral Dissertations
The goal of the dissertation work outlined here was to investigate the influence of proximal processes contributing to evolutionary differences in phenotypes among primate species. There are numerous previous comparative analyses of gene expression between primate brain regions. However, primate brain tissue samples are relatively rare, and my results have contributed to the pre-existing data on more well-studied primates (i.e. humans, chimpanzees, macaques, marmosets) as well as produced information on more rarely-studied primates (i.e. patas monkey, siamang, spider monkey). Additionally, the primary visual cortex has not previously been as extensively studied at the level of gene expression as other brain …
The Bioethical Significance Of “The Origin Of Man’S Ethical Behavior” (October 1941, Unpublished) By Ernest Everett Just And Hedwig Anna Schnetzler Just, Theodore Walker Jr.
The Bioethical Significance Of “The Origin Of Man’S Ethical Behavior” (October 1941, Unpublished) By Ernest Everett Just And Hedwig Anna Schnetzler Just, Theodore Walker Jr.
Journal of the South Carolina Academy of Science
Abstract –
E. E. Just (1883-1941) is an acknowledged “pioneer” in cell biology, and he is perhaps the pioneer in study of egg cell fertilization. Here we discover that Just also made pioneering contributions to general biology and evolutionary bioethics.
Within Just’s published contributions to observational cell biology, there are substantial fragments of his theory of ethical behavior, a theory with roots in cell biology. In addition to such previously available fragments, Just’s fully developed theory is now available. This recently discovered unpublished book-length manuscript argues for the biological origins of ethical behavior (evolving from cells to humans, within a …

Distribution And Evolution Of Fukushima Dai-Ichi Derived 137cs, 90sr, And 129i In Surface Seawater Off The Coast Of Japan, Jennifer A. Kenyon, Ken O. Buesseler, Núria Casacuberta, Maxi Castrillejo, Shigeyoshi Otosaka, Pere Masqué, Jessica A. Drysdale, Steven M. Pike, Virginie Sanial
Research outputs 2014 to 2021
© 2020 American Chemical Society. The Fukushima Dai-ichi Nuclear Power Plants (FDNPPs) accident in 2011 led to an unprecedented release of radionuclides into the environment. Particularly important are 90Sr and 137Cs due to their known health detriments and long half-lives (T1/2 ≈ 30 y) relative to ecological systems. These radionuclides can be combined with the longer-lived 129I (T1/2 = 15.7 My) to trace hydrologic, atmospheric, oceanic, and geochemical processes. This study seeks to evaluate 137Cs, 90Sr, and 129I concentrations in seawater off the coast of Japan, reconcile the sources of contaminated waters, and assess the application of 137Cs/90Sr, 129I/137Cs, and …
The Finch Effect: Evolutionary Metaphors And Illiberal Democracy In Central And Eastern Europe, Abigail Woodfield
The Finch Effect: Evolutionary Metaphors And Illiberal Democracy In Central And Eastern Europe, Abigail Woodfield
Claremont-UC Undergraduate Research Conference on the European Union
In recent years, several states in Central and Eastern Europe have seen democratic digression. Such illiberal resurgences came as a surprise to the many political scientists who assumed that the future of these states was democratic. Indeed, after the fall of the Soviet Union, the world largely regarded liberal democracy as the predominant system of government. The future seemed bright, and it was tempting to understand that future in evolutionary terms—just as humans evolved under natural selection to become the dominant species, democracy had survived a similar competition and defeated all other systems of government to become the dominant regime. …
Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff
Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff
Animal Sentience
Chapman & Huffman argue that the cognitive differences between humans and nonhuman animals do not make humans superior to animals. I suggest that humans have domain-general cognitive abilities that make them superior in causing uniquely complex changes in the world not caused by any other species. The ability to conceive of and articulate a claim of rights is an example. However, possession of superior cognitive ability does not entitle humans to superior moral status. It is sentience, not cognitive complexity, that is the basis for the assignment of rights and the protections under the law that accompany them.
Octopi-Ing A Unique Niche In Comparative Psychology, Jennifer Vonk
Octopi-Ing A Unique Niche In Comparative Psychology, Jennifer Vonk
Animal Sentience
Mather’s work has been fundamental in informing scientists of the relatively mysterious behavior and cognition of an understudied group of animals – the cephalopods. This work helps to fill a gap in the comparative literature that has historically sought evidence for complex behavior only in species that are closely related to humans or share important ecological features such as social complexity.
Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan
Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan
Animal Sentience
Humans have long viewed themselves in a favorable light. This bias is consistent with a general pattern of self-enhancement. Neural systems in the medial prefrontal cortex underlie this way of thinking, which, even when false, may be beneficial for survival. It is hence not surprising that we often disregard contrary evidence in believing ourselves superior.
Selection Perception: Views On The Theory Of Evolution Among Residents Of Moshi, Tanzania, Robin Waterman
Selection Perception: Views On The Theory Of Evolution Among Residents Of Moshi, Tanzania, Robin Waterman
Independent Study Project (ISP) Collection
The theory of evolution is a major tenet of biological science and has many practical applications, particularly in agriculture, medicine, and conservation. Nevertheless, there is significant opposition to the theory and its incorporation into school curricula, largely on religious grounds. This disconnect between public opinion and scientific opinion has been studied at length in the US and to some extent in other industrialized nations, but little is known about the issue in other communities around the world. This paper will use the town of Moshi, Tanzania as a case study in community views and knowledge about the theory of evolution. …
Can They Suffer?, Todd K. Shackelford
Can They Suffer?, Todd K. Shackelford
Animal Sentience
We should treat sentient nonhuman animals as worthy of moral consideration, not because we share an evolutionary history with them, but because they can suffer. As Chapman & Huffman (2018) argue, humans are not uniquely disconnected from other species. We should minimize the suffering we inflict on sentient beings — whether human or nonhuman — not because they, too, are tool-makers or have sophisticated communication systems, but because they, too, can suffer, and suffering is bad.
Animal Suicide: An Account Worth Giving?, Irina Mikhalevich
Animal Suicide: An Account Worth Giving?, Irina Mikhalevich
Animal Sentience
Peña-Guzmán (2017) argues that empirical evidence and evolutionary theory compel us to treat the phenomenon of suicide as continuous in the animal kingdom. He defends a “continuist” account in which suicide is a multiply-realizable phenomenon characterized by self-injurious and self-annihilative behaviors. This view is problematic for several reasons. First, it appears to mischaracterize the Darwinian view that mind is continuous in nature. Second, by focusing only on surface-level features of behavior, it groups causally and etiologically disparate phenomena under a single conceptual umbrella, thereby reducing the account’s explanatory power. Third, it obscures existing analyses of suicide in biomedical ethics and …
The Emotional Brain Of Fish, Sonia Rey Planellas
The Emotional Brain Of Fish, Sonia Rey Planellas
Animal Sentience
Woodruff (2017) analyzes structural homologies and functional equivalences between the brains of mammals and fish to understand where sentience and social cognition might reside in teleosts. He compares neuroanatomical, neurophysiological and behavioural correlates. I discuss current advances in the study of fish cognitive abilities and emotions, and advocate an evolutionary approach to the underlying basis of sentience in teleosts.
Consciousness Is Not Inherent In But Emergent From Life, Jon Mallatt, Todd E. Feinberg
Consciousness Is Not Inherent In But Emergent From Life, Jon Mallatt, Todd E. Feinberg
Animal Sentience
Reber’s theory of the cellular basis of consciousness (CBC) is right to emphasize that we should study consciousness (sentience) in its simplest form, taking its evolution into account. However, not enough evidence is presented to support CBC’s unorthodox claim that even simple, one-celled organisms are conscious. As pointed out by other commentators, the CBC seems to be based on outdated ideas about evolution and does not acknowledge that consciousness could be an evolutionary novel feature. Such emergent features are abundant in living organisms. We review our own emergentist solution, in which consciousness evolved in the elaborating nervous systems of the …
Cognitive Continuity In Cognitive Dissonance, David R. Brodbeck, Madeleine I. R. Brodbeck
Cognitive Continuity In Cognitive Dissonance, David R. Brodbeck, Madeleine I. R. Brodbeck
Animal Sentience
Zentall’s (2016) model of cognitive dissonance is compatible with cognitive continuity between humans and nonhumans. It may help explain cognitive dissonance-like behavior in many species, including humans. It is also consistent with Tinbergen’s (1963) ‘four whys’ in ethological explanation.
The Development And Expression Of Canine Emotion, Allison L. Martin
The Development And Expression Of Canine Emotion, Allison L. Martin
Animal Sentience
In her review of canine emotions, Kujala (2017) discusses how humans often attribute emotions such as fear, love, and jealousy to their canine companions. This attribution is often dismissed as anthropomorphism, suggesting that only humans can possess these emotions. I argue that emotions are not something we possess but features of certain behavioral patterns. Both human and canine emotions arise through evolution and conditioning; examining their development and expression may lead to new insights about both canine and human behavior.
How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans
How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans
Animal Sentience
The sudden appearance of consciousness that Reber posits in creatures with flexible cell walls and motility rather than non-flexible cells walls and no motility involves an evolutionary discontinuity. This kind of “miracle” is required by all “discontinuity” theories of consciousness. To avoid miraculous emergence, one may need to consider continuity theories, which accept that different forms of consciousness and material functioning co-evolve but assume the existence of consciousness to be primal in the way that matter and energy are assumed to be primal in physics.
“Cellular Basis Of Consciousness”: Not Just Radical But Wrong, Brian Key
“Cellular Basis Of Consciousness”: Not Just Radical But Wrong, Brian Key
Animal Sentience
Reber (2016) attempts to resuscitate an obscure and outdated hypothesis referred to as the “cellular basis of consciousness” that was originally formulated by the author nearly twenty years ago. This hypothesis proposes that any organism with flexible cell walls, a sensitivity to its surrounds, and the capacity for locomotion will possess the biological foundations of mind and consciousness. Reber seeks to reduce consciousness to a fundamental property inherent to individual cells rather than to centralised nervous systems. This commentary shows how this hypothesis is based on supposition, false premises and a misunderstanding of evolutionary theory. The cellular basis of consciousness …
Beginnings: Physics, Sentience And Luca, Carolyn A. Ristau
Beginnings: Physics, Sentience And Luca, Carolyn A. Ristau
Animal Sentience
According to Reber’s model, Cellular Basis of Consciousness (CBC), sentience had its origins in a unicellular organism and is an inherent property of living, mobile organic forms. He argues by analogy to basic physical forces which he considers to be inherent properties of matter; I suggest that they are instead the stuff of scientific investigation in physics. I find no convincing argument that sentience had to begin in endogenously mobile cells, a criterial attribute of the originator cell(s)for sentience according to CBC. Non-endogenously mobile cells, (i.e., plants or precursors) in a moving environment would suffice. Despite my concerns and the …
Fish Pain: An Inconvenient Truth, Culum Brown
Fish Pain: An Inconvenient Truth, Culum Brown
Culum Brown, PhD
Whether fish feel pain is a hot political topic. The consequences of our denial are huge given the billions of fish that are slaughtered annually for human consumption. The economic costs of changing our commercial fishery harvest practices are also likely to be great. Key outlines a structure-function analogy of pain in humans, tries to force that template on the rest of the vertebrate kingdom, and fails. His target article has so far elicited 34 commentaries from scientific experts from a broad range of disciplines; only three of these support his position. The broad consensus from the scientific community is …
Slavery, Welfare And The Sixth Extinction, Stephen R. Clark
Slavery, Welfare And The Sixth Extinction, Stephen R. Clark
Animal Sentience
Ng’s laudable concern for animal welfare would be welcome to any sensible slave-owner wishing to preserve his investment. What welfarism – for slave-owners and animal husbandmen – fails to call into question is whether we have the right to breed, hold captive and kill animals at all: If it matters, as the widely recognized slogan of ‘Five Freedoms’ suggests, that animals have the chance to live a ‘normal’ life, then more matters than keeping them ‘happy’ in subjection. Their lives – and also the lives of wild things – also deserve respect.
A Systems Approach To Animal Communication, Eileen A. Hebets, Andrew B. Barron, Christopher N. Balakrishnan, Mark E. Hauber, Paul H. Mason, Kim L. Hoke
A Systems Approach To Animal Communication, Eileen A. Hebets, Andrew B. Barron, Christopher N. Balakrishnan, Mark E. Hauber, Paul H. Mason, Kim L. Hoke
Eileen Hebets Publications
Why animal communication displays are so complex and how they have evolved are active foci of research with a long and rich history. Progress towards an evolutionary analysis of signal complexity, however, has been constrained by a lack of hypotheses to explain similarities and/or differences in signalling systems across taxa. To address this, we advocate incorporating a systems approach into studies of animal communication—an approach that includes comprehensive experimental designs and data collection in combination with the implementation of systems concepts and tools. A systems approach evaluates overall display architecture, including how components interact to alter function, and how function …
