It is well known fact, all we want to know what is new.
I take the privilege in sharing with the zeolers which I came to know as new or current.

Chicken came before Egg. This has been puzzled with our human minds for thousands of years - which came first, chicken or egg?

A team from the Universities of Sheffield and Warwick has found that protein called ovocledin (OC-17) is crucial in the formation of eggshells. It is produced in the pregnant hen's ovaries: Hence it must be that the chicken came first.

Chickens form 6grams of shell every 24 hours quicker than any other species.
