Ed Yong’s book explores the fascinating sensory worlds of animals and advocates for greater empathy towards other species.
The mysteries and marvels of animal senses have long captivated scientists and enthusiasts alike. From the giant squid’s football-sized eyes to the electric abilities of over 350 fish species, the unique sensory experiences of animals continue to astound and intrigue us. In this year’s winner of the £25,000 Royal Society Trivedi science book prize, “An Immense World” by Ed Yong, readers are taken on an epic journey through the diverse sensory perceptions of creatures big and small. Yong’s book not only delves into the intricacies of animal perception but also serves as a powerful reminder of the importance of empathy and understanding towards other species.
Unveiling Hidden Worlds
Yong’s book begins by taking readers into the labs of sensory biologists around the world. These dedicated scientists have made groundbreaking discoveries that have shed light on the hidden worlds of animal senses. Their research has revealed that animal senses are not merely adaptations to their environments but have often driven the course of evolution itself. For example, primates’ ability to perceive red colors likely aided them in finding food, but it also led to the evolution of patches of bare skin that flush red to communicate with others. Similarly, the giant squid’s enormous eyes have evolved to detect their formidable predator, the sperm whale, by sensing the bioluminescence emitted by jellyfish.
Curiosity and Empathy
Yong’s fascination with sensory biology is evident throughout the book, and he highlights the unique perspectives of the scientists he interviews. Many sensory biologists themselves have atypical sensory experiences, such as face blindness or color blindness. Their different ways of perceiving the world enable them to empathize with creatures that have similar experiences. The core message of “An Immense World” is one of curiosity and empathy, urging readers to value and understand animals for their own sake. Yong’s own experiences with his pet corgi, Typo, have been shaped by his research, particularly a study that revealed dogs’ increased optimism after engaging in two weeks of sniffing tasks, allowing them to fully utilize their powerful sense of smell.
Humans’ Astonishing Senses
While exploring the sensory worlds of animals, Yong also highlights the remarkable sensory abilities possessed by humans. Although our eyesight and sound detection are impressive, they are surpassed by certain creatures like killer flies and birds of prey, or owls and cats, respectively. However, humans have the capacity to augment their senses as well. Yong introduces readers to a blind American who navigates using echolocation, a technique commonly associated with bats and dolphins. By clicking and listening to the echoes, this individual has developed a unique way of perceiving the world.
The Destructive Impact of Sensory Pollution
Yong’s book also addresses the detrimental effects of human activities on animal senses. The increasing prevalence of noise and light pollution in our anthropogenic world has significant consequences for animal populations. LED lights, for example, have been found to be particularly harmful to bats and insects, leading to reduced pollination and disrupted ecosystems. The rise of low-frequency noise in oceans due to global shipping has also impaired the communication abilities of whales. Yong emphasizes that these issues require urgent attention and highlights the negative impact of traffic noise on bats and birds.
Solutions and Environmental Preservation
While the challenges posed by sensory pollution may seem daunting, Yong provides hope by showcasing practical solutions. Simple changes like swapping LED lights to red hues can reduce harm to bats and insects. Similarly, reducing ship speeds has been shown to significantly decrease engine noise in the sea. Yong argues that addressing these issues not only benefits animal populations but also has a positive impact on environmental preservation. For instance, playing sounds of healthy reefs underwater can attract baby fish back to damaged reefs, offering a potential strategy for reef restoration.
Conclusion:
“An Immense World” by Ed Yong is a captivating exploration of the sensory experiences of animals and a call for greater empathy towards other species. Through his engaging storytelling and in-depth research, Yong highlights the wonders of animal senses while shedding light on the destructive impact of human activities. By understanding and valuing the sensory lives of other creatures, we can work towards preserving the natural world and fostering a more harmonious coexistence with the diverse species that share our planet.
