Dasyurid marsupials—comprising quolls, antechinuses, phascogales and allied genera—exhibit a remarkable array of reproductive tactics underpinned by life‐history trade-offs between survival, growth ...

Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research shows that the typical mammalian heater ...
