Misteri mengenai kewujudan ayam dan telur telah lama disebut2 sejak dahulu lagi.. Ramai memberi teori2 menarik tentang sapa yang muncul terlebih dahulu namun segala nye telah terungkai apabila kajian mendapati ayam terhasil dahulu barulah telur.. (link)
....Understanding how they build eggs would begin to tell us how we can do it ourselves. And so we turned to the UK Science Research Council's super-computer based in Edinburgh called HECToR (High End Computing Terascale Resource). We wanted it to figure out how eggs are built, by looking at the process in microscopic detail.
First we programmed in the "ingredients" that chickens use to make egg shells. We then said: "Right, this is what chickens use - off you go and see what you can do." This computer tinkered away on the problem for weeks and weeks. A chicken, on the other hand, can do this pretty much overnight. The funny thing is we weren't even originally going to use chicken eggs. We only chose them because the protein was simple to study. It was only when we got our results back that we realised we had solved this timeless riddle. We were pretty amazed.
The results showed that a particular protein in chickens acts as a tireless builder, placing one microscopic section of shell on top of the other. It initiates this building process before going off to start on another part of the egg. Without this builder protein, the eggs would not exist. And yet it is only found in a chicken's ovaries. This means the bird must have come first.. (link)
هَلْ يَنْظُرُوْنَ اِلَّا تَاْوِيْلَهٗؕ يَوْمَ يَاْتِىْ تَاْوِيْلُهٗ يَقُوْلُ الَّذِيْنَ نَسُوْهُ مِنْ قَبْلُ قَدْ جَآءَتْ رُسُلُ رَبِّنَا بِالْحَـقِّۚ فَهَل لَّـنَا مِنْ شُفَعَآءَ فَيَشْفَعُوْا لَـنَاۤ اَوْ نُرَدُّ فَنَعْمَلَ غَيْرَ الَّذِىْ كُنَّا نَـعْمَلُؕ قَدْ خَسِرُوْۤا اَنْفُسَهُمْ وَضَلَّ عَنْهُمْ مَّا كَانُوْا يَفْتَرُوْن[7:54] Do they wait only for the fulfillment of warnings thereof? On the day when the fulfillment thereof shall come, those who had forgotten it before shall say, ‘The Messengers of our Lord did indeed bring the truth. Have we then any intercessors to intercede for us? Or could we be sent back so that we might do deeds other than that which we used to do?’ They have indeed ruined their souls and that which they used to fabricate has failed them.
[7:54] هَلۡ يَنظُرُونَ إِلَّا تَأۡوِيلَهُ ۥۚ يَوۡمَ يَأۡتِى تَأۡوِيلُهُ ۥ يَقُولُ ٱلَّذِينَ نَسُوهُ مِن قَبۡلُ قَدۡ جَآءَتۡ رُسُلُ رَبِّنَا بِٱلۡحَقِّ فَهَل لَّنَا مِن شُفَعَآءَ فَيَشۡفَعُواْ لَنَآ أَوۡ نُرَدُّ فَنَعۡمَلَ غَيۡرَ ٱلَّذِى كُنَّا نَعۡمَلُۚ قَدۡ خَسِرُوٓاْ أَنفُسَہُمۡ وَضَلَّ عَنۡہُم مَّا ڪَانُواْ يَفۡتَرُونَ
وَاللّٰهُ خَلَقَ كُلَّ دَآبَّةٍ مِّنْ مَّآءٍ ۚفَمِنْهُمْ مَّنْ يَّمْشِىْ عَلٰى بَطْنِهٖۚ وَمِنْهُمْ مَّنْ يَّمْشِىْ عَلٰى رِجْلَيْنِ وَمِنْهُمْ مَّنْ يَّمْشِىْ عَلٰٓى اَرْبَعٍؕ يَخْلُقُ اللّٰهُ مَا يَشَآءُؕ اِنَّ اللّٰهَ عَلٰى كُلِّ شَىْءٍ قَدِيْرٌ
[24:46] And Allah has created every animal from water. Of them are some that go upon their bellies, and of them are some that go upon two feet, and among them are some that go upon four. Allah creates what He pleases. Surely, Allah has the power to do all that He pleases.Source: (link)
