Cracking The Chicken Egg Puzzle.

What came first, the chicken or the egg? Now, 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 northen and central England, say the secret lies in the eggshell - specially the vital role played by a chicken protein in forming it.

Scientists already knew that the protein, vocleddin-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. In a computer simulation, the OC-17 protein acted as a catalyst to kick start the formation of crystals that make up an eggshell by clamping itself onto calcium carbonate particles.

The OC-17 protein than dropped off when the crystals nucleus was large enough to grow on its own, freeing up the protein to start the process again. Eggshell are created when this happen many times over within a short period of time.

Understanding how chicken make eggshells is fascinating in itself but can also gives clues towards designing new material and processes, said Prof John Harding from Sheffield University, one of the auhors 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.

Akhirnya dengan pencarian dan kajian, manusia menemui kebenaran wahyu Al Quran berkaitan dengan penciptaan haiwan sebagaimana dirakamkan dalam ayat berikut yang maksudnya:

"Dan Dialah yang menciptakan langit dan bumi, Dia menjadikan bagi kamu pasangan-pasangan dari jenis kamu sendiri dan menjadikan dari jenis-jenis binatang-binatang ternak pasangan-pasangan (bagi binatang-binatang itu) dengan jalan yang demikian dikembalikanNya (zuriat keturunan) kamu semua. Tiada sesuatu pun yang sebanding dengan (ZatNya, sifat-sifatNya dan pentadbiranNya) dan Dia lah Yang Maha Mendengar lagi Maha Melihat"

(Surah Asy Syuura, 42:11)
