Which Came First_ The Chicken Or The Egg Brightside Egg

Which came first: the chicken or the egg?

00:00 Well, looky here. Scientists may have solved the mystery of the chicken and the egg. A new study

00:05 suggests that the ancestors of chickens may have given birth to live babies instead of laying eggs.

00:11 Previously, it was believed that these ancient reptiles laid eggs with hard shells,

00:16 but the study challenges this idea. Instead, the researchers proposed that these creatures

00:21 practiced extended embryo retention, keeping the babies inside them for a while. This protected

00:27 the developing reptiles from drying out in warm climates and allowing them to conquer dry land.

00:33 The study shows that lizards and snakes are more flexible than previously thought,

00:37 able to switch between laying eggs and giving birth. So, the chicken came first, not the egg.

00:43 Now I'm getting hungry.
