When researchers "rewilded" lab mice to large, enclosed fields, even well-established anxieties in the mice disappeared.

Lucky breaks in a male mouse’s youth can lead to large advantages in adulthood, especially in groups that compete for food, territory and mates.

Cornell researchers have found that when laboratory mice are placed in large outdoor enclosures, male behavior was essentially the same as genetically wild mice, but females displayed radically different behaviors.

Genomic sequencing revealed that populations of wasps that recognized each other's faces – and cooperated more – showed recent adaptations in areas of the genome associated with cognitive abilities such as learning, memory and vision.

Paper wasps (Polistes fuscatus) recognize the brightly colored faces of other paper wasps, an ability they lose when reared in isolation. The wasps’ ability to remember faces is similar to primates and humans, but unlike other social insects...

New research indicates facial recognition abilities in paper wasps evolved relatively rapidly, suggesting that their increasing intelligence provided an incredible evolutionary advantage. This new research also sheds light on how intelligence evolves in general, which has implications for many other species – including humans.
