Life on Earth may have developed the ability to form embryos even before it grew the very first animals.

    Multicellular animal organisms all start their lives the same way. Two zygotes merge and fuse

    I hate to nitpick but asexual reproduction does not require two zygotes.

    Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.

      Those are examples of far-fetched, never observed things that do not happen with any frequency that can be measured. It’s so rare, in fact, that a genetic trait would be able to be discerned because there would never be a divergent genetic material.

      I don’t think that’s what the article is suggesting.

        Asexual reproduction has been observed, measured, studied and is fairly well understood.

        The specific claim that all multicellular life starts with two zygotes merging is incorrect. While not the main thrust of the article it is wrong.

        Your additional claims are simply absurd and you could spend some minimal effort to understand asexual reproduction before making ignorant claims.

          Read your own link. These are all observed after the fact, and the catalyst is not understood. The frequency is also not tied to avian or warmbloods which is even more rare than a mechanism that exists in certain life forms already.

          What are you talking about?

            What are you talking about?

            It is known as a fact that asexual reproduction does occur and does not involve the merging of two zygotes.

            Everything else you have spouted is purely irrelevant and is deflection.

            It is clear you have too much ego to properly participate in science.
