Animal Consciousness: It’s Time to Think
Why Consciousness Matters
The idea that so many different kinds of creatures, with different kinds of minds, might have some form of consciousness raises questions – including ethical ones – that we can't yet fully answer. However, if consciousness, however basic, is far more widespread than we’ve suspected, the way we relate to other animals must fundamentally change.
Take fish, for example. Fish are the most farmed and fished animals on Earth. According to the U.N. Food and Agriculture Organization, global aquaculture production of fish reached 122.6 million tons in 2021, while 90.3 million tons of fish were captured in the wild, with over half destined for human consumption. In short, we are using and killing fish on a massive scale. If these fish are conscious and capable of experiencing pain and suffering, as recent research suggests they are, then our treatment of them may demand a thorough rethink.
Evolution of consciousness
Furthermore, researchers studying the evolution of consciousness propose that it arose as a solution to a particular kind of problem in the animal world. To survive and reproduce, an animal must find and consume food and mates, all while avoiding becoming food for another creature. To tackle these challenges, animals evolved different ways of sensing and interacting with their environments. The more sophisticated an animal’s sensing and processing abilities became, according to this view, the more likely it was to gain a type of consciousness. Even rudimentary consciousness, scientists think, would help animals make better decisions. That ability, in turn, would lead to more complex behaviors and adaptations, which could further increase the creature’s chances of surviving to pass on its genes.

The Search for Answers
But to understand the origins and evolution of consciousness, scientists must first be able to recognize it in other animals. While consciousness may be subjective, the behaviors associated with it can help us identify its presence. This is where the concept of “convergent evolution” comes into play.
In biology, convergent evolution describes the process whereby unrelated species independently develop similar traits or features as a result of adapting to the same kinds of environmental pressures. A classic example is the independent evolution of wings in bats, birds and insects as a way to tackle the challenges and opportunities of powered flight. In the same way, the authors of the declaration suggest that if different species that share similar environmental pressures also independently evolved complex behaviors suggestive of consciousness, it reinforces the view that those behaviors are likely tied to conscious experiences.
Moreover, by focusing on behavior, biologists, cognitive scientists and philosophers of mind hope to skirt the hard problem of consciousness – the philosophical challenge of explaining how and why the subjective character of conscious feelings and experiences arises from biological processes.
Beyond Behavior
But while studying animal behavior provides important clues about animal minds, it can only take us so far. In the case of humans, we don’t have to rely on observations of behavior alone. We can also ask each other what it feels like to be us. This approach is not yet possible with any other non-human animal, of course. But recent advances in neuroimaging and other technologies are giving researchers some ways to correlate animal behaviors with neural or brain-state signatures, allowing us to ask what goes on in the brain when an animal behaves as it does.
A New Frontier
The idea that animals as diverse as octopuses, bumblebees and fish might have some form of consciousness presents us with both great promise and great challenges. On the one hand, it brings us closer to understanding what it means to be human – why we think and feel and do what we do – by forcing us to ask, what makes us fundamentally different from other animals, if anything? On the other hand, it raises difficult questions about the suffering of animals and our ethical obligations toward them.
While there’s still much we don’t know, the fact that a prominent group of scientists has put their names on a declaration that formally recognizes this possibility signifies a shift toward a more inclusive view of consciousness – one that recognizes that minds have evolved in myriad ways, not just in animals like ourselves who have similar brains, but also in animals whose nervous systems and ways of interacting with their environments are radically different. This view of consciousness in the animal world presents a new frontier – one in which we might learn as much about ourselves as we do about the many other sentient beings with whom we share this planet.
Animal Consciousness: Challenges of Perception
The very concept that non-human creatures might experience consciousness often faces resistance. Our ingrained human bias influences our perceptions of other lifeforms. We might judge the intelligence of an octopus or a bee based on our own experiences and ways of thinking. This narrow viewpoint can lead us to underestimate their complex capabilities.
One of the biggest challenges is that we tend to equate consciousness with intelligence. While these two concepts may be related, they are not identical. An organism can be conscious without possessing a sophisticated language system or the ability to build a rocket, for example. In fact, some animals may have forms of consciousness that we can't even begin to fathom – ones that are closely attuned to their particular sensory and survival needs.
For instance, consider bees. Their minuscule brains have evolved to manage complex navigational tasks with impressive efficiency. They understand abstract concepts like size and number, and communicate information to their nestmates about the location of rich food sources. However, we simply lack the sensory apparatus to imagine what those experiences might feel like for the bees themselves. Just because we can't relate doesn't diminish the possible existence of consciousness.

Obstacle to understanding animal consciousness
Another obstacle to understanding animal consciousness is that we humans rely heavily on language. It's how we communicate, form complex thoughts, and express our inner experiences. Naturally, we tend to assume that animals lacking sophisticated language have simple minds. However, this is an anthropocentric perspective that overlooks the many other ways that animals communicate and process the world around them.
Octopuses, for example, can change the color and pattern of their skin in remarkably complex ways – not only for camouflage but also, it seems, as a form of communication. Meanwhile, the intricate waggle dances that honeybees perform to indicate foraging spots demonstrate remarkable communicative complexity without spoken words.
Rethinking Our Relationships
Acknowledging consciousness in more diverse species may lead to profound changes in our relationship with the natural world. Recognizing that creatures like fish or insects might experience pain and suffering could have wide-reaching implications for industries like farming and fishing. We might need to develop more humane methods of rearing animals for food or reconsider intensive factory farming practices altogether.
However, the potential benefits of wider recognition of animal consciousness go beyond minimizing cruelty. A deeper understanding of other creatures' ways of sensing and experiencing the world could inform new technologies or spark innovations in fields like robotics and artificial intelligence.
Studying how insects navigate could lead to better algorithms for autonomous vehicles, just as understanding octopus camouflage techniques might revolutionize materials science. The potential for breakthroughs inspired by animal minds is vast and largely unexplored.
The declaration on animal consciousness represents a significant shift in scientific understanding. If we can move beyond our human-centric perspectives and embrace the possibility that consciousness is a gradient rather than a binary state, we open a new world. One filled with ethical considerations, potential applications, and, above all, an expanded respect for the astonishing diversity of life on our planet.
The Ethical Implications
The notion that a broad range of animals might have some degree of consciousness raises complex ethical questions that will need careful consideration. For many people, the way we treat animals is fundamentally based on the belief that they're vastly different from us. If we begin to question that difference, how will it change the way we interact with and use other species?
One immediate concern is animal welfare. If a fish or an octopus can feel pain, it calls into question our current practices in commercial fishing and aquaculture. Similarly, if insects experience distress, their use in laboratory experiments deserves re-examination.
Challenge extends
The challenge extends into the broader question of how we relate to other conscious animals. Should they be granted legal rights, and if so, what would those rights look like? Could a time come when deliberately inflicting suffering on a conscious animal is considered a crime? These are profound questions that require careful philosophical debate.
Some might argue that humans remain superior to other animals, even if those animals are conscious, and our interests should always take priority. This line of thinking, known as speciesism, draws parallels with arguments used to defend racism or sexism. If we reject those prejudices, some philosophers argue, we should also reject the assumption that our species alone has moral standing.
A Spectrum of Consciousness
It's also important to acknowledge that consciousness likely exists on a spectrum. This idea is reflected in the wording of the New York Declaration, which emphasizes the "realistic possibility" of consciousness in the groups of animals discussed. It's conceivable that a bee has a less rich form of consciousness than, say, a chimpanzee, but that doesn't necessarily mean it can't feel pain or pleasure.
Where we draw the line will undoubtedly be a subject of intense debate. Should we extend the same ethical considerations to a crayfish as we do a dog? What about a caterpillar compared to a chimpanzee? These complex questions don't have simple answers. They highlight the need for nuanced discussions about the ways we treat different species, with consciousness as a guiding factor.
Expanding Our Circle of Compassion
Ultimately, recognizing animal consciousness might lead us to expand our circle of moral concern while deepening our sense of connection with the other lifeforms we live alongside. It's humbling to contemplate that the capacity for conscious experience might be far more widespread in the animal kingdom than we once imagined.
This awareness has the potential to shift our mindset toward greater respect and care. For example, imagine if we approached our interactions with animals from a place of curiosity and wonder instead of assuming a position of dominance. How could this impact our willingness to conserve habitats, protect endangered species, or simply coexist peacefully with our animal neighbors?
While ethical considerations might be the most pressing, they are far from the only impacts of recognizing animal consciousness. This shift in our understanding also has the potential for significant advancements in our relationship to the natural world as a whole.
Beyond Ethics: The Transformative Power of Recognizing Animal Consciousness
Shifting our perspective on animal consciousness could also have profound implications that reach far beyond ethics. It might lead to a deeper understanding of ourselves, new technological breakthroughs, and a transformed relationship with the world around us.
The Search for the Origins of Mind
One way in which this shift might impact us is that it fuels our innate curiosity about the origins of the human mind. After all, we are not separate from the animal kingdom. While human consciousness is clearly exceptional in many ways, we evolved from the same ancestral life forms as all other animals. Recognizing the potential for consciousness in a range of creatures pushes us to ponder how and when consciousness emerged in its various forms.
Studying the complex behaviors and nervous systems of animals with different evolutionary histories could help us unravel the biological roots of our own consciousness. This search has the potential to unlock new insights into what makes us human. What specific neural systems or evolutionary leaps were key to the development of our highly complex form of self-awareness and mental life?
Inspiration for Innovation
The natural world has already served as a rich source of inspiration for engineering, technology, and design solutions. This process, called biomimicry, could become even more valuable as we appreciate the astonishing capabilities of animals once overlooked.
For example, understanding the principles behind an octopus's camouflage could lead to revolutionary new materials that change appearance in response to stimuli. Studying the navigation systems of bees might refine algorithms for self-driving vehicles or swarm robotics. The possibilities are vast and could lead to innovations with applications ranging from medicine to environmental technologies.
A Deeper Connection to Nature
Perhaps most importantly, recognizing animal consciousness could foster a deeper sense of connection with the natural world. Moving away from a purely anthropocentric perspective inspires a sense of awe and wonder. It may remind us that we share the planet with a multitude of beings with unique experiences and ways of understanding reality.
This expanded view of life could spark a heightened commitment to conservation. It may drive us to advocate for policies that prioritize the well-being of diverse species and protect their habitats. Such a shift could even lead to a more equitable and sustainable way of living, where we respect the inherent worth of all forms of life and take our responsibility as caretakers of the planet seriously.
Understanding that animals also experience the world in subjective ways can profoundly change what it means to be human. It expands our sense of empathy and challenges the belief that we alone possess a rich inner life. The potential impacts – ethical, scientific, and philosophical – are far-reaching and demand careful thought and open discussion.
A Call for Openness and Respect
The New York Declaration on Animal Consciousness serves as a reminder of how much we still have to learn about the minds of other creatures. While the scientific evidence is compelling, it's important to remember that it's difficult for humans to fully grasp the subjective experiences of other species.
The authors of the declaration acknowledge this limitation, emphasizing the "realistic possibility" of consciousness. They advocate for a more open-minded approach, one that acknowledges both the potential for different forms of consciousness and the uncertainty that remains.
A crucial aspect of this shift is developing a greater respect for animals, even for those that seem vastly different from ourselves. Instead of assuming a lack of cognitive sophistication, we can adopt a perspective of curiosity and wonder.
This doesn't necessarily mean granting personhood or human-level rights to other species. However, it suggests that we shouldn't dismiss their inherent worth or their capacity for experiences like pleasure, pain, or fear.
The Future of Animal Consciousness Research
The field of animal consciousness research is poised for exciting expansion in the years to come. New technologies, such as brain-imaging techniques adapted for use in animals, could provide more direct insights into their neural activity and how it relates to their behaviors. Additionally, cross-disciplinary studies in animal behavior, neuroscience, and artificial intelligence have the potential to uncover new and unexpected links in the evolution of consciousness.
While scientists continue to unravel these mysteries, it's important that these discoveries don't just remain in academic journals. The declaration calls for greater public awareness and discussion to inform policymaking and to reshape our interactions with other creatures.
A Changing Mindset
Ultimately, the true impact of the growing awareness of animal consciousness may be a fundamental shift in our mindset. The potential exists to move from a position of dominance and assumed superiority to one of coexistence marked by respect and humility. It could ignite a stronger sense of kinship with all beings on this planet we call home.
Perhaps one day, we'll look back on this moment as a turning point in the human story, a time when we moved away from a blinkered, species-centric view and finally opened our minds to the astonishing possibilities of the many ways of experiencing our incredible world. The implications of this shift are profound – impacting ethics, scientific discovery, and our very sense of what it means to be alive on Earth.
