Question

Which one came first egg or hen

Answer 1

Hi friend,

Your question is

Which one came first,egg or hen?

Here's your required answer:-

We can not say confirm whether an egg or hen came first. 

Because, if we think that hen came first, then how would hen come?
Answer is from egg. 

But if we think that egg is first, then who laid eggs? 
Answer is hen. 

But scientifically, hen came first because eggs are produced from hens. Hens have a protein in their ovaries. 
The protein – called ovocledidin-17 (OC-17) – acts as a catalyst to speed up the development of the shell.
Scientists used a computer to zoom in. 
It showed OC-17 was crucial in kick-starting crystallisation.

The protein coverts calcium carbonate into calcite crystals which makes up the egg shell, creating six grammes of shell every 24 hours.

hope it helps...

Answer 2

Answer:

The egg

Explanation:

Chickens would have evolved from a previously existing animal such as a dinosaur. Dinosuars lay eggs and chickens hatch from eggs so from thousands of generations of mutation, the chicken would have been formed. However, due to the chicken hatching from an egg, the chicken egg would have come first.
