Read our COVID-19 research and news.

Humans are animals, and from beetles to whales, we are all related. But just how much do we really know about the creatures that share this Earth? New technologies are allowing us to deeply probe the animal mind for the first time, revealing complex behaviors and emotions, while our ever-evolving relationship with these beings is forcing us to confront how we study them and protect them in a changing world. Here we present the latest news and research that is moving us forward in our attempts to better understand our animal relatives, and in so doing, ourselves.
