Two flying squirrel species chewed grooves into Cyclobalanopsis nuts, and used them to pressure-fit nuts tightly in crotches formed by small twigs on understory plants, in a way similar to a mortise-tenon joint used in architecture and carpentry.
In the rain forests of Hainan, China, two species of squirrel create grooves on the surface of smooth nuts so that they can wedge them in the forks between branches.
New evidence that neighboring communities of bonobos hunt different prey species, despite extensive overlaps in where they live and hunt, is difficult to explain without invoking cultural factors.
In this episode, we hear about how flies taste salt, animal personalities, fossil flowers and flying squirrels, and the impact of climate change on seal pups.

Novel heart rate strategies that minimize energy expenditure during the day are necessary to cope with high energy nocturnal lifestyles of tent-making bats.
The evolutionary loss of the main enzyme required for ketone body biosynthesis suggests that alternative strategies to provide energy for large brains during fasting evolved repeatedly in mammals.
