What came first, the chicken or the egg? It’s an age-old scientific and philosophical mystery that’s stumped generations of scientists, has finally been solved, according to scientists. Scientists now believe they have cracked the puzzle of “what came first?” It’s the chicken!
Which came first, chicken or egg?
The chicken came first, scientists said cracking the mystery, whether the chicken or the egg came first!
How? Role of protein OC-17
According to British researchers “the chicken must have come first because the formation of egg shells is only possible due to a specific protein found only in a chicken's ovaries; hence an egg can exist only if it has been inside a chicken.
The protein called ‘ovocledidin-17’, or ‘OC-17’, works as a medium to speed up the growth of the shell.
It had long been assumed that the egg came first but now scientists have the considerable scientific proof which shows that ‘the chicken came first. Research says, protein ‘ovocledidin-17’ is linked to egg formation and controls the process. Protein OC-17 is very crucial in crystallization - the early stages of forming a shell.
Protein OC-17 coverts calcium carbonate into calcite crystals which makes the egg shell, it creates six gram of shell every day.
