An Immense World

This is one of those books that will change the way you view the animals of the world. We take for granted just how amazing and mind-blowing the animal senses are and just accept them for being the way they are. Or maybe that's just me. But this has absolutely changed my view on a lot of things. I will certainly not look at an animal the same, even my dog.

There is a whole crap ton of information on here, so do not expect this to be a quick read. However, Young does a really great job of giving you the abundance of information in a way that doesn't make you feel like you're in a college class.

I did listen to the audiobook which Young reads himself. He did a really great job with his cadence and pacing so would definitely recommend the audiobook if you would be interested in it.

I cannot say enough about this book, read it!

“Five senses,” they told me. How chauvinistic that seems now. Understandably so, but still.

Remember [book:Flatland|433567]? (I like to think everyone read that in grade school but am now wondering if it was only us math geeks?) Anyhow, Immense World brought back those feelings of wonder; of imagining what we know is out there but can never, ever fully understand. A dog navigating the world through smell. The countless ways of arranging color receptors, giving some animals a visual experience we can barely even describe. Touch. Vibration, through air (sound) and through ground. Sensing electrical fields. Magnetic fields! How little we know! And of course, [book:bats|197189543]. All creatures taking their senses for granted, just like we do, but we have that amazing ability to study and learn and devise instruments that help us see-hear-sense farther. And to imagine.

“[...] we can try to step into their worlds. We must choose to do so, and to have that choice is a gift. It is not a blessing we have earned, but it is one we must cherish.” Yong, more than anyone else I’ve ever encountered or heard of, has made me recognize that gift. Has let me glimpse those worlds of sensation. He does so with tremendous compassion and humility.

An impressive book, full of wonderful facts and some grounded speculations looking at how various creatures sense, and make sense, of the world around them. Ed Yong (the author) reminds us that trying to understand the behaviour of creatures based on what we can sense can be futile. And by forcing creatures into a human centric world (near constant lighting at night, urban noise, artificial chemicals in the environment), we may be altering their behaviour and damaging the natural biodiversity.

Ed Yong starts by introducing the reader to the term, Umwelt (as used by biologist Jakob von Uexkül) to represent each creature's unique perception of the world. He then shows us the Umwelts of various creatures as experienced through the various senses: smell, taste, light, colour, the sensation of pain and heat, contact, vibrations and sound. He then covers three of the more mysterious senses; echolocation and the ability to sense electric and magnetic fields. Each sense is shown by giving examples of various creatures whose ability to use the sense differs and/or exceeds our abilities to use them.

He then closes the book by showing how animals draw upon the various senses to form each creature's Umwelt, and how we are altering what creatures are sensing from their surroundings by 'polluting' the environment with our lights, noise and artificial chemicals.

Throughout the book, Ed Yong features the research and work being done by numerous researchers to understand how creatures sense the world and, possibly, how they make sense of the world using the information provided by the senses.

It may be impossible to fully imagine how even familiar creatures like dogs sense the world compared to us, much less creatures like spiders, birds, fishes, electric eels, moles or elephants (all examples from the book). But Ed Yong gives it a good try, and by the end, you'll probably appreciate the fact that we may never share the Umwelt of other creatures, but you'll be aware that they see the world differently from us and that needs to be accounted for when trying to understand why they behave in certain ways that may seem puzzling to us, limited as we are by our own Umwelts.
