À propos de ce contenu audio
Brought to you by Penguin.
Humans have three or four colour-detecting cones in their retinas. Mantis shrimp have 16. In fact, their eyes seem to have more in common with satellite technology than with biological vision as we currently understand it. They have evolved to track movement with an acuity no other species can match by processing raw information; they may not 'see', in the human sense, at all.
Marine molluscs called chitons have eyes that are made of stone. Scorpions appear to see with their entire bodies. It isn't only vision that differs from species to species—some animals also have senses we lack entirely. Knifefish navigate by electrical charge.
An Immense World will take us on an insider's tour of the natural world by describing the biology, physics and chemistry animals use to perceive it. We may lack some of their senses, but our own super-sense lies in our ability to understand theirs. And in the face of the largest extinction event since the meteor that killed the dinosaurs, our only hope of saving other species is bound up with our ability to see what they see, and feel what they feel.

The term “Umwelt” is introduced at the beginning of the book, which is a German term for “home”. Scientists are now analyzing animals from their own Umwelt, meaning their own sensory bubble, instead of framing it within our (human) senses and therefore misinterpreting information. I must say, I am quite surprised this is such a revelation, what with all the talk about not imposing our views on others and to try understand we all view the world differently, I imagined this included animals. But I guess this is neither here nor there…
Ed Yong also bemoans the damage civilization is causing and even comments on us humans not having earned the right to carry on such experiments on animals. However, he then justifies such actions by claiming that this is probably our greatest sensory skill.
If we used this sensory skill on humans it would be considered unethical and torture, would it not? This is further proof that humans are not part of nature, we are destroying it. We use findings to create solutions to problems we cause.
This book left me wondering about the human perception of the world, but even more so, it left me wondering how ethical testing for mere curiosity is.
Very good
