Genetic Entropy: Sal Cordova vs Ron Garret

Spread the love

We remember Sal Cordova fondly:

We believe as things speciate they lose allele variety and inherit more mutations. This shows us clear limitations with evolution, and shows that ancestrally that things were superior than today.

Dollo’s law of irreversibility also shows us that evolution cannot go in reverse, so when they lose this genetic information after speciation, they can never regain it. This is why all horses today are now homozygous and horses in the past were heterozygous. They cannot return to their once superior state allowing for more diversity.

We didn’t realize that people still took Dollo’s Law seriously.

    Darwinian clowns … whatever they ever claimed, it always turned out to be WRONG.

    Dollo’s law of irreversibility ????? These Darwinian clowns …

    “Dollo’s law of irreversibility also shows us that evolution cannot go in reverse, so when they lose this genetic information after speciation, they can never regain it”

    WHAT ????

    I run a blog, where Dollo’s law is falsified again and again and again and again….

    let me show you just 2 examples:

    “A family of lizards has achieved something very unexpected, evolving to give birth to live young, before going back to egg laying. Most remarkably, the zoologists who observed this think it is possible they rediscovered laying eggs multiple times.”
    https://www.iflscience.com/plants-and-animals/lizards-reevolve-to-lay-eggs-after-having-already-evolved-to-give-birth-to-live-young-/

    or

    “Can complex traits be re-evolved by lineages that have lost them? Phylogenetic study now suggests that wings may indeed have reappeared several times within the ancestrally wingless stick insects. ”

    and one more example where Dollo’s law is falsified by Darwinians who invented it !!!!

    “The re-evolution of a coiled shell, or any complex character, is considered unlikely or impossible (Dollo’s law) because the loss of the character is followed by the loss of the genetic architecture and developmental mechanisms that underlie that character. Here, we quantify the level of coiling in calyptraeids, a family of mostly uncoiled limpets, and show that coiled shells have re-evolved at least once within this family. These results are the first demonstration, to our knowledge, of the re-evolution of coiling in a gastropod, and show that the developmental features underlying coiling have not been lost during 20-100 Myr of uncoiled evolutionary history. This is the first example of the re-evolution of a complex character via a change in developmental timing (heterochrony) rather than a change in location of gene expression (heterotopy).”

    PS: to be honest, i understand, why Darwian Mr. Dollo believed that complex trait can’t be re-evolved :)))))) Darwinian Mr. Dollo obviously did not believe in miracles unlike other Darwianian clowns…

    and here is another MIRACULOUS one …

    “This type of placental structure has arisen several times during Poeciliopsis evolution (Kwan, et al. 2015) and has been subsequently lost and regained many times, making it a model for the evolution of placentation (Pollux, et al. 2014).”

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5033709/

    PS:
    lets don’t forget, a placenta is extremely complex organ, even today it is still unclear how it works … and it requires a co-operation of both, mother and child, that adds another layer of complexity.

    Martin_r,
    Excellent contributions as usual.
    Thanks.

    Did you see the list of papers that cite the one you cited?

    Jawa, thank you.
    I just had a look at the list, i do not follow…

    Martin_r,

    Just wanted to note that it’s quite a long list.

    🙂

    Watched the video of the debate. Sal caught Ron unprepared for the new material he presented so unexpectedly. Sal’s presentation was really interesting. Unfortunately he was forced to skip a substantial portion of it when the host let him know that he ran out of time.
    Is his presentation available online somewhere?
