Your Sense of Smell Is Better Than You Think

The video explores the human sense of smell, challenging the misconception that humans have a poor olfactory sense compared to other mammals. It discusses the historical context of this belief, originating from 19th-century neuroanatomist Paul Broca, and presents recent studies showing humans can detect certain scents as well as or better than some animals. The video also highlights biodiversity discoveries, such as the rare Lord Howe Island stick insect, and conservation efforts. It concludes with a call to support SciShow through Patreon.
