Tbh, it's common sense that you'd need a chicken before a chicken egg... only a chicken can lay a chicken egg, otherwise it's some kind of other egg.
Science wasn't even necessary!
True, and yet the chicken is a genetic mutation of another "chickenlike" prehistoric animal and probably was born in an egg.

I fail to see what is sensationalist or pointless about researching how eggs are formed so we can use the techniques to form similar materials of our own...
my brother used to be deathly allergic to eggs
