Humanity has done great things on Earth over the ages. Now it turns out that humans have also directed the evolution of bears to some extent.
One study documents the genetic evolution of the small population of brown bears of the Apennines, who live next to villages in central Italy and have remained isolated from other bears for 1,500 years: they are smaller and less aggressive than their European relatives. Read
Have interactions with humans made bears less aggressive?
Have human-led changes led to the evolution of smaller, less aggressive bears in a population found only in Central Italy?Photograph of an Apennine brown bear.

As human activity shapes landscapes, some animal species adapt or disappear. In Central Italy, a population of brown bears, isolated since Antiquity, has seen its behaviour evolve with constant contact with surrounding villages. These bears of the Apennines, now smaller and less aggressive than their cousins in Europe or America, embody a rare case of behavioral evolution influenced by human proximity. A study conducted by researchers at the Uni…
