Why do birds lay eggs?

Wednesday 13th Mar 2019, 09.00am

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 ;-)
