What Came First, The Chicken or The Egg?

What came first, the chicken or the egg? Scientists in Britain think it was probably the chicken, after using new computer technology to try and crack the age-old riddle.

Researchers at the Universities of Sheffield and Warwick, in northern and central England, say the secret lies in the eggshell – specifically the vital role played by a chicken protein in forming it.

Scientists already knew that the protein, vocledidin-17 (OC-17), plays a part in eggshell formation, but the new technology allowed the team to demonstrate exactly how the protein makes it happen.

Simulating eggshell crystals

In a computer simulation, the OC-17 protein acted as a catalyst to kickstart the formation of crystals that make up an eggshell by clamping itself on to calcium carbonate particles.

The OC-17 protein then dropped off when the crystal nucleus was large enough to grow on its own, freeing up the protein to start the process again.

Eggshells are created when this happens many times over within a short period of time.

Eggshells point to new technology

“Understanding how chickens make eggshells is fascinating in itself but can also give clues towards designing new materials and processes,” said John Harding from Sheffield University, one of the authors of the research.

“Nature has found innovative solutions that work for all kinds of problems in materials science and technology – we can learn a lot from them,” he added.

    Finally, we have solved old puzzle. Chicks came first. Wow!

  2. You can’t see the forest for the trees… because the answer is obviously “Both.” The original joining of two compatible single-celled organisms would have given rise to a new set of characteristics, which, of course, changed the animal’s functions and behavior mechanisms, allowed for adaptations and speciation. “Ontogeny recapitulates phylogeny.” biology 101

    Yeah, agreed!

    what do you mean from ‘original joining’?
