Frog-hunting bats have ‘cocktail party effect’ workaround
Test with robotic frogs finds bats that hunt amphibians switch their attention to other clues if outside noise masks the mating chorus.
- Life
Rattlesnakes have reduced their repertoire of venoms
The most recent common ancestor of today’s rattlesnakes had a huge set of toxin-producing genes. Modern rattlesnake species have independently ditched some of these genes.
