Understanding Human and Animal Senses

The video discusses the human sense of smell, challenging the misconception that humans have a poor olfactory sense compared to other mammals. It highlights historical misconceptions and recent studies showing humans can detect certain scents as well as or better than some animals. The video also covers biodiversity discoveries, including the rediscovery of the Lord Howe Island Stick Insect, and efforts to preserve unique species. It concludes with a call to support SciShow.
