  1. The egg appeared earlier, as chickens descended from dinosaurs that also laid eggs. You can continue this chain even further back in time, and reach the simplest organisms that are clearly closer to the egg than to the chicken

  2. The question is asked approximately once a week. The last time was on January 6, before that on January 2.

    So that the system does not delete the link to the previous fifty answers to this question, I will give one of the answers, mine:

    There is a predkuritsa and a pre-petukh. The sun is shining, there is all sorts of radiation, other mutagens. And now the egg or sperm, the carriers of information about the future child of the pre-chicken and pre-baby, are damaged. The ancestress lays a fertilized egg with a defect, but the defect is such that the new creature turns out to be a chicken.

    Then there will be a question – what was the first, pre-chicken or pre-chicken egg.

    Eggs-caviar as a method of reproduction appeared long before fish. All sorts of worms, for example, invertebrates, also multiply in this way.

    In the end, this question will be reduced to a question:

    what was before — DNA or DNA ))

    After all DNA is the most important thing an egg and a chicken:

    In living organisms, almost all processes occur mainly due to enzymes of a protein nature. Proteins, however, cannot self-replicate and are synthesized de novo in the cell based on information stored in the DNA. But the doubling of DNA occurs only due to the participation of proteins and RNA. A vicious circle is formed, because of which, in the framework of the theory of the spontaneous generation of life, it was necessary to recognize the need not only for abiogenic synthesis of both classes of molecules, but also for the spontaneous emergence of a complex system of their interrelation.

    The next theory and hypothesis was that RNA can exist completely autonomously, and it was the first chicken-egg.

    That is, seriously, the question of the topic – where did the DNA and RNA come from?

    The first traces of life are now considered to be eoarchean stromatolites, products of cyanobacterial communities. This means that life appeared very quickly – at the same time as the solid earth's crust.

  3. Chicken, because chicken is the subject of a relationship, and the object is an egg. An egg can't give birth to a chicken by itself. It must be hatched, and who will hatch it? Chicken. No matter what you call it, it's an ancient creature. Let it be “chicken”.
