Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez
Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez
Animal Sentience
Chapman & Huffman argue that, because humans are neither unique nor superior to the other animals, cruelty to animals is not justified. Though I agree with their conclusion, I do not think their argument works. Many human beings do have some capacities that animals do not have and are greater in some respects, in the sense of having superior abilities. It is a better argument to deny that any of that is morally relevant. Sentience suffices for moral consideration, and for deriving a moral duty not to harm other animals and to assist them when they are in need.
Humans Have Always Been Unique!, William C. Mcgrew
Humans Have Always Been Unique!, William C. Mcgrew
Animal Sentience
Arguments about human uniqueness apply not only to extant species but also to extinct ones, that is, the hominin predecessors of anatomically modern Homo sapiens. Thus, unique and superior are doubly relative terms, in past and present. The scope for empirical comparison faces a spectrum of difficulty, from material (e.g., artefacts) to non-material (e.g., concepts) phenomena.
Phooey On Comparisons, Gwen J. Broude
Phooey On Comparisons, Gwen J. Broude
Animal Sentience
Chapman & Huffman reject the notion that human beings are very different from other animals. The goal is to undermine the claim that human uniqueness and even superiority are reason enough to treat other animals badly. But evaluating human uniqueness for this purpose only plays into the hands of those who exploit invidious comparisons between us and other animals to justify mistreatment of the rest of the animal kingdom. What human uniqueness we may discover would still be no justification for how we behave toward other animals. We should also ask ourselves whether any human-centric criterion can be justification for …
Anthropomorphism Is The First Step, Marthe Kiley-Worthington
Anthropomorphism Is The First Step, Marthe Kiley-Worthington
Animal Sentience
Individuals have intentions, beliefs and choices. This sense of “personhood” has been known and used for centuries by those who have dealt professionally with any nonhuman mammal. All mammals have a lot in common physically and mentally. The first step toward understand another species’ point of view is anthropomorphism.
Intelligence As Mental Manipulation In Humans And Nonhuman Animals, Moran Bar-Hen-Schweiger, Avishai Henik
Intelligence As Mental Manipulation In Humans And Nonhuman Animals, Moran Bar-Hen-Schweiger, Avishai Henik
Animal Sentience
Chapman & Huffman review and evaluate various aspects of the notion of human superiority. In this commentary we focus on intelligence and suggest a biologically based view of intelligence applicable to humans and non-human species alike. “Mental manipulation” (e.g., mental transformations, rotations, perspective-taking), an extension of object manipulation, provides a continuous, biologically based concept for studying intelligent behavior in humans and other species and challenges the notion of human superiority.
Taking Exception To Human Exceptionalism, Carrie P. Freeman
Taking Exception To Human Exceptionalism, Carrie P. Freeman
Animal Sentience
Chapman & Huffman refute common claims used to justify human species distinctions, and they critique the animal cruelty that has resulted from this privileged status. I raise related questions for further study of the roots of human exceptionalism and about whether aspiring to be more like our fellow animals might be part of the solution.
Sharing Emotions Builds Bridges Between Individuals And Between Species, Elisabetta Palagi
Sharing Emotions Builds Bridges Between Individuals And Between Species, Elisabetta Palagi
Animal Sentience
Many animal species express, perceive and share emotions. These abilities have been favoured by natural selection because they allow subjects to respond to various situations in an appropriate way, thus facilitating survival and increasing fitness. The same-face/same-emotion phenomenon is at the basis of sharing feelings and emotions. Recent studies show that this capacity is not unique to humans and that it plays an important role in creating cohesive societies in many different species.
Phenotypic Similarity And Moral Consideration, S. Brian Hood, Sophia Giddens
Phenotypic Similarity And Moral Consideration, S. Brian Hood, Sophia Giddens
Animal Sentience
Identifying specific traits to justify according differential moral status to humans and non-human animals may be more challenging than Chapman & Huffman suggest. The reasons for this also go against their recommendation that we ought to attend to how humans and non-humans are similar. The problem lies in identifying the moral relevance of biological characteristics. There are, however, other reasons for treating non-human animals as worthy of moral consideration, such as the Precautionary Principle.
Anthropocentrism: Practical Remedies Needed, Helen Kopnina
Anthropocentrism: Practical Remedies Needed, Helen Kopnina
Animal Sentience
It is true that one of the harmful consequences of creating categories where one group is unique and superior to others is that it justifies discriminating against the inferior groups. And outright abuse of nonhuman animals is indeed morally unjustifiable. But what is to be done about it?
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.

“I Am Not An Animal”, Lori Marino
“I Am Not An Animal”, Lori Marino
Animal Sentience
The answer to Chapman & Huffman’s question — “Why do we want to think humans are different?” — lies in the work of Ernest Becker and the social psychology literature known as Terror Management Theory, according to which our deep anxiety about animality and death can drive our need to feel superior to the other animals.
Across The Great Divide, Debra Merskin
Across The Great Divide, Debra Merskin
Animal Sentience
Chapman & Huffman’s target article calls for a reevaluation of claims of human uniqueness and superiority. It also adds to the literature on how species differences, as Darwin noted, are more of degree than kind. The threats to environmental health and species survival are a consequence of excluding nonhuman animals from moral concern and consideration. The theory of intersectionality should include speciesism in the array of discriminatory practices.
Mobilizing Heads And Hearts For Wildlife Conservation, Valérie A. M. Schoof, Simon L'Allier
Mobilizing Heads And Hearts For Wildlife Conservation, Valérie A. M. Schoof, Simon L'Allier
Animal Sentience
Highlighting the shared evolutionary relationships between humans and animals — and recognizing that all species, including humans, are unique in their own way — may facilitate caring for and conserving animals by tapping into a human emotion: empathy.
Moral Relevance Of Cognitive Complexity, Empathy And Species Differences In Suffering, John Lazarus
Moral Relevance Of Cognitive Complexity, Empathy And Species Differences In Suffering, John Lazarus
Animal Sentience
I qualify two criticisms made by commentators on Chapman & Huffman’s target article. Responding to the view that differences between humans and other animals are irrelevant to deciding how we should treat other species, I point out that differences between any species in their capacity to suffer are morally relevant. And in response to the claim that suffering is the sole criterion for the moral treatment of animals, I argue that cognitive complexity and a capacity for empathy also have moral relevance to the extent that they influence suffering.
Animal Cognition: Quantity Has A Quality Of Its Own, Ivaylo Borislavov Iotchev, Kauê Machado Costa
Animal Cognition: Quantity Has A Quality Of Its Own, Ivaylo Borislavov Iotchev, Kauê Machado Costa
Animal Sentience
Chapman & Huffman’s moral analysis fails to prove that the exploitation of animals or the environment is causally connected to beliefs about human capacities. Their exposition of the philosophical interpretations of animal cognition ignores historical context and confounds different levels of analysis. Their analysis of the scientific literature, from which they conclude that humans should not be considered as different from other animals, does not take into account many recent psychological and neuroscientific developments and rests upon a flawed understanding of the relationship between gradual and categorical differences, misrepresenting the two as mutually exclusive concepts.
Corticocentric Bias In Cognitive Neuroscience, Orit Nafcha, Shai Gabay
Corticocentric Bias In Cognitive Neuroscience, Orit Nafcha, Shai Gabay
Animal Sentience
Chapman & Huffman (2018) note that our tendency to categorize leads to a sense of human superiority that helps justify violence against nonhuman animals. Yet animals are turning out to have capacities previously thought to be uniquely human. We add a further factor that may contribute to the false sense of human superiority: the "corticocentric" bias of neuroscience. An evolutionary approach may help identify species similarities and differences, providing a better understanding of the uniqueness of each species.
Taking Darwinism Seriously, Carsta Simon
Taking Darwinism Seriously, Carsta Simon
Animal Sentience
Chapman & Huffman propose that dropping the categorical distinction between human and nonhuman animals may reduce the atrocious acts of humans towards nonhuman animals, but will it? Taking Darwinism seriously means accepting physical and behavioral continuity across species, including the capacity to feel pain.
Refining Thoughts About Human/Nonhuman Differences, Colin A. Chapman, Michael A. Huffman
Refining Thoughts About Human/Nonhuman Differences, Colin A. Chapman, Michael A. Huffman
Animal Sentience
Our commentators come from many fields and disciplines and express highly divergent views, illustrating broad interest in the question. From the breadth of comments, we have identified two recurring themes, which we focus on here. The first is a preponderance of cautionary remarks about evaluating the differences between humans and nonhuman animals. The second concerns whether considering animals as worthy of moral consideration is one of many useful tools for conservationists trying to prevent extinction, habitat destruction, and climate change.
Why Cod Don't Like To Sunbathe: Quantity And Quality In The Animal Kingdom, Christoph Jung
Why Cod Don't Like To Sunbathe: Quantity And Quality In The Animal Kingdom, Christoph Jung
Animal Sentience
The difference between a cod and a lizard is not just a quantitative one. The recognition of qualitative differences between species does not imply a moral ranking. Our species’ special abilities to shape the earth mean we have a special responsibility for ensuring a liveable future for all organisms, human and non-human.
Superior Or Inferior, Human Uniqueness Is Manifold, Scott Atran
Superior Or Inferior, Human Uniqueness Is Manifold, Scott Atran
Animal Sentience
Chapman & Huffman (C & H) contend that, as with all biological traits, there is evolutionary continuity underlying cognitive and social traits previously thought to be unique to humans. Yet C & H, like Darwin, appeal to a seemingly unique moral aptitude that enables humans to be kind to conspecific strangers and other species.
Diversity On Human Difference: Unanimity On Human Responsibility, Colin A. Chapman, Michael A. Huffman
Diversity On Human Difference: Unanimity On Human Responsibility, Colin A. Chapman, Michael A. Huffman
Animal Sentience
Further commentaries on our original target article add important new points and expand our understanding of the differences between animals, particularly between non-human and human primates. But whether they affirm or deny that humans are unique, all commentators agree that our special abilities mean we should be taking responsibility for the care of nature and the plants and animals it supports. We ask: is humankind doing this?
A Cohort-Based Program To Help Students Prepare A Conference Research Presentation, Alanna Lecher
A Cohort-Based Program To Help Students Prepare A Conference Research Presentation, Alanna Lecher
Florida Statewide Symposium: Best Practices in Undergraduate Research
Students move through many first time experiences when navigating their undergraduate and graduate education. Such experiences include the first time students submit an article to a peer-reviewed scientific journal, attend a conference, and conduct fieldwork. The cohort model has been shown to be effective in increasing success in undergraduate education, and it can be adapted to helping students succeed in these novel experiences as well. This presentation will explore one program where the cohort model was implemented to aid undergraduate students preparing their first conference presentation on a scientific research project. Program structure and implementation will be described.

Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack
Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack
Theses
Bubble stream production in belugas has been poorly characterized and its function is not well understood. I examined behavioral states when producing bubble streams (“bubbling”), and when bubbling calls, to determine whether bubbling was significantly associated with a particular call category or behavioral state. Using 19 hours of video and audio recordings collected over a two-day period, I quantified bubble streams of a 4-month old calf and an unrelated adult female housed together. Based on the overall activity budgets and pool of vocalizations for both animals, I calculated the expected counts of bubble streams with and without vocalizations, assuming that …
Personality In California Sea Lions (Zalophus Californianus) And Harbor Seals (Phoca Vitulina): Methodological Convergence And Species-Specific Emotional Repertoires, Amber De Vere
Dissertations
Despite the wide acceptance of animal personality as a valid area of study, research on marine mammal personality remains remarkably scarce. What literature does exist predominantly focuses on bottlenose dolphins (Frick, 2016; Highfill & Kuczaj, 2007; Kuczaj, Highfill & Byerly, 2012; Lilley, de Vere, Yeatre & Kuczaj, 2018; Moreno, Highfill & Kuczaj, 2017). There is also strong evidence for individual differences in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012), and preliminary research has provided evidence of broad personality factors in pinniped species using behavioral coding …
Social Influences On Songbird Behavior: From Song Learning To Motion Coordination, Iva Ljubičić
Social Influences On Songbird Behavior: From Song Learning To Motion Coordination, Iva Ljubičić
Dissertations, Theses, and Capstone Projects
Social animals learn during development how to integrate successfully into their group. How do social interactions combine to maintain group cohesion? We first review how social environments can influence the development of vocal learners, such as songbirds and humans (Chapter 1). To bypass the complexity of natural social interactions and gain experimental control, we developed Virtual Social Environments, surrounding the bird with videos of manipulated playbacks. This way we were able to design sensory and social scenarios and test how social zebra finches adjust their behavior (Chapters 2 & 3). A serious challenge is that the color output of a …
Chickens Play To The Crowd, Cinzia Chiandetti
Chickens Play To The Crowd, Cinzia Chiandetti
Animal Sentience
The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.
Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley
Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley
Animal Sentience
Peña-Guzmán’s depiction of the opponent of animal suicide as a conservative is a straw man. It is possible to accept that animals are self-conscious and reflexive yet still reject the view that they have the mental wherewithal to commit run-of-the-mill suicide. That animal behaviour can be positioned on a continuum of self-destructive behaviour does not establish that animals can intentionally kill themselves.
An Adaptationist Perspective On Animal Suicide, Timothy P. Racine
An Adaptationist Perspective On Animal Suicide, Timothy P. Racine
Animal Sentience
Peña-Guzmán’s discussion of suicide in nonhuman animals has broad implications. In this commentary, I focus on the logical relation between suicide and intention. Proximate cause must be distinguished from ultimate function in explanations of suicide. I briefly discuss two adaptationist accounts of suicidal behavior.
