Prior to the first true chicken, there were non-chickens. The DNA changes came about in cells housed in the egg. So the egg came first. In July 2010, Britishscientists, using a supercomputer, claimed to have come up with the final and definitive answer.

Hi friend!!

#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.
