Repeated switches from cooperative to selfish worker oviposition during stingless bee evolution.

abstract：:The skulls of animals have to perform many functions. Optimization for one function may mean another function is less optimized, resulting in evolutionary trade-offs. Here, we investigate whether a trade-off exists between the masticatory and sensory functions of animal skulls using echolocating bats as model species....
