What would identical fossils in every strata imply about the organisms?

    "Identical fossils" would indicate one or both of the following: 1) That the species produced asexually (like some species of snail do) or 2) That the species mass-produced multiple identical offspring as a result of a single fertilized egg "splitting" during conception.

  • Similar fossils, such as those of the frequently referred to horseshoe crabs, found in strata that were laid down over long periods of time, imply that the species was, and is, well adapted to a particular ecological niche. I said “similar” because they are rarely identical. There are usually some differences, but still within the basic form, and are not even the same species. For example, see this article about horseshoe crabs.

    Since these species are well adapted to a particular ecological niche, there is no reason, or evolutionary pressure, for them to evolve out of that niche.Contrary to what those who do not accept evolution say, there is no evolutionary mandate that all species must evolve into different species with different forms over time. Evolution by natural selection does not “look” to the future. It pertains only to the survival of the organism long enough to reproduce under the currently existing conditions.

    I think you're trying to ask about identical fossils in every stratum.

    Depends one how quickly the different strata were laid down. for example seasonal flooding can put down many strata in a short time in which case those fossils would indicate a species that quickly recolonized disturbed area.  If the strata represented millions of years it would mean the those species did not change a lot over time indicating a stable environment.

    It was around for a long time and didn't evolve during that time.

    The species was *very* widespread and existed without noticeable evolutionary changes over a *very* long period of time.

    Sounds like a case of anagenesis.

    Perhaps convergent evolution, they develop traits similarly, therefore have similar features to adapt to their environment, perhaps it would establish they have relationships.
