Invertebrate Cognition, Sentience And Biology, Georges Chapouthier

Animal Sentience

All animal species have adapted for survival and no species is superior overall. For cognitive capacities and sentience, invertebrates such as the octopus, although quite unlike vertebrates, can achieve similar performance levels. So can other invertebrates with small brains; hence they too, as sentient beings, deserve moral consideration from humans. How are we to identify these species? Only though a detailed analysis of their behavior. The decision, which is a moral judgment, depends on biological knowledge that still needs to be acquired.

Convergent Evolution Of Sentience?, Culum Brown Prof.

Animal Sentience

Mikhalevich & Powell make a compelling case that some invertebrates may be sentient and that our moral obligations in the context of welfare should hence extend to them. Although the case is similar to that made for fishes, there is one obvious difference in that examples of invertebrate sentience probably arose independently from vertebrate sentience. We have unequivocal proof that complex cognition arose multiple times over evolutionary history. Given that cognition is our best tool for indirectly quantifying sentience, it seems highly likely that this multiple polygenesis may also have occurred for sentience. In acknowledging this, we must accept that …

Minds, Morality And Midgies, Brian Key, Deborah Brown

Animal Sentience

Mikhalevich & Powell argue that the exclusion of the vast majority of arthropods from moral standing is unwarranted, particularly given the purported evidence for cognition and sentience in these organisms. The implied association between consciousness and moral standing is questionable and their assumption that rich forms of cognition and flexible behavior are dependent on phenomenal consciousness needs to be reconsidered in light of current neuroscientific evidence. We conclude by proposing a neural algorithmic approach for deciphering whether organisms are capable of subjective experience.

Sounding The Nile: River Politics, Environment And Nubian Musical Expression, Regan L. Homeyer

Music ETDs

ABSTRACT

In the mid 1960s, almost 100,000 Egyptian Nubians, people Indigenous to the Nile River Valley, were removed from their ancestral homeland due to the creation of the Aswan High Dam. In the years surrounding their displacement, Nubian musicians in Cairo and villages in new settlement areas gathered traditional Nubian songs and composed new songs to form a distinctive Nubian musical repertoire. This thesis addresses contemporary Nubian musical performance and the role of these reclaimed and newly-written songs in maintaining and revitalizing not only Nubian languages and culture, but especially senses of self in relation to place and, above all, …

Evolutionary Bioethics Advanced By Ernest Everett Just: Implications For Biology, Ethics, And Theology, Theodore Walker

Perkins Faculty Research and Special Events

Ernest Everett Just (1883-1941) is an acknowledged “pioneer” in biology, being honored with a Black Heritage postage stamp in 1996. Here we discover that Just also made pioneering contributions to general evolutionary bioethics (distinct from special medical bioethics) by advancing a cell-biology-rooted theory of the origin and continuing evolution of ethical behavior influenced by the “law of environmental dependence.”

See especially “The Origin of Man’s Ethical Behavior (1941, unpublished book manuscript) by Ernest Everett Just and Hedwig Schnetzler Just, discovered in 2018 among the collected papers of E.E. Just at the Moorland-Spingarn Research Center at Howard University.

Accordingly, evolution is …

Rockhounding, Seafaring, And Other Material Tales For The End Of The World, Noemie Fortin

The Goose

In the face of accelerated environmental degradation and climate instability, the future of the Earth and of all life on earth is difficult to visualize. Therefore, the different mediums through which we consider environmental issues are just as important as the actions we take to address them. Focusing on three projects combining art, science, and activism, this article suggests a compilation of material tales. They tell stories of plastic rocks and aluminum nuggets where the protagonists are partly finely crafted objects, partly waste materials, and sometimes both at once. Artists Kelly Jazvac, Yesenia Thibeault-Picazo, and the collective Studio Swine collaborate …

Are Humans Natural? Part 4: Human-Nature Relational Values Through Time, Nathan Ruhl, Sirena Pimenta

Open Educational Resources

This activity assumes students have a background in evolutionary theory, so students without such a background should have additional instruction prior to conducting this part of the activity. Consider a discussion of mechanisms that drive evolution, including genetic drift, natural selection, and gene flow. Evolution is a change in gene frequencies in a population over the course of several generations.

Genes are the genetic code controlling many individual characteristics or traits, so the frequency at which genes occur dictates, in large part, the frequency at which individual characteristics or traits exist in a population. The frequency of a gene can …

Martin Luther King Jr. And Ernest Everett Just - On Evolution Of Ethical Behavior, Theodore Walker

Perkins Faculty Research and Special Events

Rev. Martin Luther King Jr. prescribed an evolutionary advance in ethical behavior: the total “abolition of poverty” and the abolition of war throughout “the world house.” Cell biologist Ernest Everett Just advanced the idea that human ethical behavior evolved from cellular origins.

Also, astrobiologists Chandra Wickramasinghe and Sir Fred Hoyle advanced the idea of cosmic biology, including stellar evolution and cosmic evolution. From cells to humans to stars and cosmology, evolutionary natural science converges with natural theology.

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 …

The Abyssinian Art Of Louis Agassiz Fuertes In The Field Museum, Paul A. Johnsgard

Zea E-Books Collection

This book documents the paintings and drawings executed by Louis Agassiz Fuertes during the Field Museum of Natural History’s seven-month expedition to Ethiopia (Abyssinia) in 1926–27. During that time Fuertes completed 70 field watercolors that illustrate 55 species of birds and four species of mammals. He also executed 34 pencil drawings, which illustrate 13 species of mammals and 11 species of birds, plus numerous miscellaneous sketches and small watercolors. This book identifies and describes the biology of all 69 species of birds and mammals illustrated by Fuertes and includes 32 color reproductions of Fuertes’s watercolors that were published as a …

Invertebrate Welfare In The Wild, Asher Soryl

Animal Sentience

Mikhalevich & Powell argue that certain cognitive-affective biases might distort people’s consideration of invertebrate minds and that the moral risks of false negatives in sentience research deserve greater consideration under precautionary frameworks. In this commentary, I draw comparisons between biases that concern wild animals and conditions in nature, arguing that the moral risks of disregarding the possible mental welfare of invertebrates are compounded by facts about their lives in the wild.

Elephants And Pandemics, Adrian Treves

Animal Sentience

Baker & Winkler’s critique of Asian elephant tourism and conservation in Thailand has convinced me that this was “an industry with too many victims.” Yet I fear that B&W’s proposed remedy of returning to past elephant husbandry by Karen hill-peoples has little likelihood of improving the lives of the elephants for long. Who can predict whether the Karen will live up to this hope? B&W advocate for the Karen, but not for “an abolitionist stance on elephant-human relationships.” In my view, whether we discuss elephants or the wild mammals that carry SARS-CoV-2, abolition of many human uses of animals is …

Appealing To Human Intuitions To Reduce Animal Abuse, Yzar S. Wehbe, Todd K. Shackelford

Animal Sentience

Social scientists may be able to find ways to positively affect people’s evolved moral compasses, thereby doing the planet and its inhabitants a great kindness. They could help to shape a constituency that is increasingly opposed to animal abuse in its largest-scale manifestations, factory farming and wet markets. This would, in turn, motivate people to elect ethical leaders who view inaction with regard to animal abuse as a serious moral and medical mistake, if only indirectly due to factory farming’s exacerbation of the threats zoonoses pose to humans.

Do Arthropods Respond To Noxious Stimuli Purely By Reflex?, Robert W. Elwood

Animal Sentience

Mikhalevich & Powell (2020) argue that it is wrong to dismiss the idea of sentience in invertebrates. Here, I expand on the evidence for crustaceans responding to noxious stimuli in ways that are not explained by mere reflexes, and that are consistent with pain. I consider the idea that male praying mantids must not feel pain because they may continue to mate whilst being consumed by the female. I finish with thoughts about the idea that because robots may be constructed to act as if they experience pain, the argument that animals might experience pain is diminished.

Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch

Gulf and Caribbean Research

I spent my nearly 50—year career in marine science working at marine laboratories, most of that as a chief executive officer. So, it is appropriate that my reflections are about marine laboratories, rather than my own science. After relating my career course, I turn my attention to the history and development of marine laboratories along the U.S. coast of the Gulf of Mexico (GOM). Surprisingly, the region’s first laboratory was actually constructed in 1903 at Cameron, LA, but operated less than a decade before closing. It was not until after World War II that the university—affiliated marine laboratories of today …

Exploring Eight-Armed Intelligence Through Film, Tierney M. Thys

Animal Sentience

Mather (2019) provides a rich overview of the elements underlying octopus cognition and behavioral flexibility. Recently, two remarkable natural history films, My Octopus Teacher and The Octopus in My House have explored intimate human-octopus relationships with a wild (Octopus vulgaris) and a captive octopus (Octopus cyanea) respectively. Both films show rare behaviors that offer observations to test new hypotheses as well as a novel perspective on our own human relationships and place within the natural world. An interview with filmmaker Craig Foster from My Octopus Teacher reveals the profound and transformative power of forming a trusting …

Preserving Nature For The Benefit Of All Sentient Individuals, Eze Paez

Animal Sentience

I agree with Treves et al.’s proposal for a preservation ethics based on the principle that nonhuman well-being is a matter of justice and compassion. In this commentary, I advance two objections. First, only sentient beings, rather than all life, belong in the moral community. Second, given that nature is probably harmful overall for sentient individuals, preserving it for the benefit of future human and nonhuman generations requires us to modify it as far as practicable.

Comparative Cognition And Nonhuman Individuality, Catia Correia Caeiro

Animal Sentience

Commentators Washington (2019) and Tiffin (2019) point out that the individual vs. collective dichotomy is much more complex than what is considered in the target article. This commentary will focus on why individuals are more important than collectives. Species differences in cognition and emotional processes and individuals’ feelings and experiences need to be taken into account.

Game Theory And Artificial Intelligence In Just Preservation, David L. Dowe, Nader Chmait

Animal Sentience

We humans can show presumption, arrogance and many dubious traits. By virtue of being land-dwelling, dexterous, relatively intelligent, and having good communication hardware and (good) fortune, we have for recent millennia largely had dominion of our planet. Yet humans often do not treat themselves (let alone other species) particularly well. Treves et al.’s idea of a multispecies justice system — not “prioritizing humans” but “finding practical ways to work within human systems” — invites consideration.

Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn

Animal Sentience

We are grateful to all the commentators who engaged with our target article. Some commentators have offered important insights into our proposed design and methods for legally intervening on behalf of futurity. Others have focused on theoretical considerations central to our proposal for multispecies justice and trusteeship. All have inspired modifications and further elaboration of our initial proposal. In this Response, we engage with the commentaries, integrating their suggestions, striving for convergence and complementarity, but also discussing points of divergence with our proposed framework where necessary. There is substantial overlap in the points of view of the three co-authors, but …

A “Halfway House” For Improving Captive Welfare, Phyllis C. Lee, W. Keith Lindsay

Animal Sentience

It is certainly time to aim for higher quality management strategies for Thailand’s captive elephants, and to engage with sustainable livelihoods for traditional mahouts. Baker & Winkler’s proposal to rewild Thai elephants by placing them under the guardianship of Karen mahouts is recognized as not “wild” since it remains a form of management requiring elephants to live under the control of human caregivers. We applaud the positive welfare aims of this proposal; however, we caution that few of the long-term consequences for elephants or habitats can be known, and further considerations of elephant population dynamics and forest ecosystems are required …

Compassionate Conservation And Elephant Personhood, Arian D. Wallach, Sujeewa Jasinghe, Sudarshani Fernando, Jessica Bell Rizzolo

Animal Sentience

Baker and Winkler (2020) advocate a rehabilitation program that would end the oppression of elephants — not by severing human-elephant relations, but by enabling human-bonded elephants to live a full life. We consider this program within a compassionate conservation framework, which recognises all sentient beings as persons. From this vantage point, we gaze further into the future to ask what direction just human-elephant relations could take: What could emerge from a human-elephant relation once elephants are no longer enslaved and requiring rescue? We envisage a future — beyond captivity and rewilding — of elephant sovereignty.

Rewilding And Domestication: Clarifying Terminology, Catia Correia-Caeiro

Animal Sentience

Baker & Winkler (B&W) describe the state of Asian elephant conservation, raising unique issues, and proposing a direction based on rewilding. The long history and socio-biology of elephants and humans has some parallels with the domestication of dogs (and other species). However, markers of domestication seem absent from elephants. The proper use of terms such as “wild” and “domestic” is crucial in defining the best conservation strategies, and, more important, in attending to the welfare needs of individuals, which can differ between wild and domestic animals. B&W’s target article represents an important starting point for discussion around elephant conservation, but …

Future Of Thailand's Captive Elephants, Antoinette Van De Water, Michelle Henley, Lucy Bates, Rob Slotow

Animal Sentience

Removal from natural habitat and commodification as private property compromise elephants’ broader societal value. Although we support Baker & Winkler’s (2020) plea for a new community-based rewilding conservation model focused on mahout culture, we recommend an expanded co-management approach to complement and enhance the regional elephant conservation strategy with additional local community stakeholders and the potential to extend across international borders into suitable elephant habitat. Holistic co-management approaches improve human wellbeing and social cohesion, as well as elephant wellbeing, thereby better securing long-term survival of Asian elephants, environmental justice, and overall sustainability.

Rewilding And Mixed-Community Collaboration In Conservation, Liv Baker

Animal Sentience

Rewilding is a psychological and sociocultural event for nonhuman animals that goes beyond the traditional framework of ecology. Elephants need to be seen as political agents in a collaboration. Our commentators shed light on the hierarchical assumptions and politics involved. Mixed-community collaboration can create dynamic and sustainable conservation interventions that are crucial to reconceptualizing the human-elephant relationship beyond the concept of labor. The profound effects of the Covid-19 pandemic have laid bare the fundamental vulnerabilities of the elephant tourism industry. Moreover, how well an elephant has been buffered by the fallout of the pandemic is dependent on the specific relations …

Global Risks Of Intensive Animal Farming And The Wildlife Trade, Deborah Cao

Animal Sentience

This commentary discusses two issues highlighted by Wiebers & Feigin in the context of the current and future global health crisis: the wildlife trade and factory farming. Both are instances of globalized animal cruelty – in China as well as worldwide -- that require global solutions for the well-being of both humans and nonhumans.

Innovation In Meat Production: A Problem And An Opportunity, Christopher J. Bryant

Animal Sentience

Innovation in meat production has enabled modern humans to inflict far greater harm on animals, the environment, and public health than was possible just a few decades ago. Wiebers & Feigin aptly express the urgency with which these issues must be addressed. Those advocating for animals on moral grounds face resistance from omnivores citing taste, price and convenience. Further innovation in meat production (plant-based and cultured meat) will enable us to preserve the experience of eating meat whilst phasing out the many problems caused by industrial animal farming.

Harm, Earth Jurisprudence And Human/Nonhuman Relationships, Tanya Wyatt

Animal Sentience

To prevent the next pandemic and to protect the environment and non-human animals, there needs to be a clear definition of harm and a legal system grounded in Earth Jurisprudence. Drawing on evolutionary principles to redefine harm and to radically alter the legal system to be Earth-centred will help ensure that harmful actions like certain wildlife trade, wildlife trafficking, and intensive farming do not threaten the survival of any life.
