When the 1st vertebrates - that's, the 1st creatures along with backbones - visited oceanic towards reside ashore, they experienced an obstacle.
Their eggs, just like those of present day fish, were actually dealt with merely in a slim coating referred to as a membrane layer. The eggs will promptly completely dry out up as well as pass away when left open towards sky.

Residential hens merely started showing up a long time within recent 10,000 years.
This suggests hard-shelled eggs just like the ones hens lay are actually more mature compared to hens on their own through virtually 200 thousand years. Therefore complication dealt with, straight?
