Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan Jan 2019

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.

Is Human Uniqueness Fake News?, Sean Hermanson Jan 2019

Is Human Uniqueness Fake News?, Sean Hermanson

Animal Sentience

The world and its troubles don't need unfounded denials of human uniqueness.

“I Am Not An Animal”, Lori Marino Jan 2019

“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 Jan 2019

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 Jan 2019

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.

Animal Cognition: Quantity Has A Quality Of Its Own, Ivaylo Borislavov Iotchev, Kauê Machado Costa Jan 2019

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 Jan 2019

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 Jan 2019

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 Jan 2019

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 Jan 2019

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 Jan 2019

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 Jan 2019

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?

Happy Or Hangry Families: Does Kinship Mediate Cooperation And Cannibalism In Drosophila Melanogaster Larvae?, Lucas Khodaei Jan 2019

Happy Or Hangry Families: Does Kinship Mediate Cooperation And Cannibalism In Drosophila Melanogaster Larvae?, Lucas Khodaei

Theses and Dissertations (Comprehensive)

The fruit fly Drosophila melanogaster has a long history as a research model for studies on behaviour and group dynamics. When individuals are grouped in an environment and resources decrease, then they may behave co-operatively with one another or antagonistically compete. Hamilton’s Law states that if the benefit of helping a related individual out-weighs the cost to its direct fitness, then the individual’s indirect fitness will increase when they help their kin compared to helping an unrelated stranger. Yet it is unknown whether kinship mediates larval behaviour to encourage co-operation and/or lessen antagonistic behaviours between consanguineous individuals. In this thesis …
