Most new-born mammals and some reptiles emerge from their mothers through the usual channels. But baby birds are stuck cracking open eggshells – but why?
In this week’s Oxford Sparks Big Questions podcast we are visiting Marie-Claire Koschowitz, evolutionary biologist and asking: Why do birds lay eggs?
Warning: parents if you don’t want to have the birds and bees conversation you may want to listen to this one on your own ;-)
