The last eukaryotic common ancestor (LECA) seems to have been pretty complex. So when and where does all that random assembly of vital equipment for life from free-floating chemicals actually happen?
Question: If the last common ancestor of the bacterium had a flagellum, what do we really know about the evolution of the flagellum? Isn’t that a bit like finding a stone laptop in a Neanderthal cave? That said, it’s nice to see horizontal gene transfer getting proper recognition.
Woese as “scarred revolutionary”? He had to fight hard to get the Archaea, the third kingdom of life, accepted. He regretted that he had not succeeded in overthrowing “the hegemony of the culture of Darwin.”
Darwinian Ernst Mayr cast doubt on hybridization as an important source of change so for decades few believed it could be. Now, says one researcher, the consensus is that it “is hugely widespread and much more common than was appreciated.” But isn’t hybridization cutting into a lot of the things Darwinism supposedly did?
Kershenbaum wipes out, unfortunately, when he tries to claim that human culture is genetically based.
Didn’t we just used to call this process crossbreeding? How did it get upgraded to “assisted evolution?” If it’s crossbreeding, it isn’t unintelligent, which evolution is supposed to be.
David Klinghoffer: The paper acknowledges an “explosive increase in dinosaurian abundance.” As Dr. Bechly says, that’s the kind of observation you wouldn’t be surprised at coming from the dreaded “creationists,” and yet it’s a straightforward finding of mainstream paleontology. Watch the rest below, and enjoy.
Well then, how did a complex process like photosynthesis get the time to “evolve” by natural selection acting on random mutations (Darwinism)? Researchers (wisely, for now) state such findings without making any obvious inferences. But the number of these situations is building.
It’s anyone’s guess how much of this will hold up, but positing some numbers to dispute is a worthwhile effort at sleuthing.
Life would be simpler and more emotionally satisfying if birds were surviving dinosaurs but maybe they aren’t.
Readers may remember J. Scott Turner, author of Purpose and Desire: What Makes Something “Alive” and Why Modern Darwinism Has Failed to Explain It. He was taking a risk even putting things that way (we thought he’d been Canceled a while back) but now he has a new video series out.
Of course, one outcome of a shorter period during which oxygen is stable enough for complex life is — the obvious one — that all that bewildering complexity of life had to just sort of fall into place in a shorter period of time. If that’s unlikely, it’s an argument for underlying design.
We heard just recently about horizontal gene transfer between herring and smelt. Will we be hearing next about horizontal gene transfer involving mammals via airborne DNA? Don’t rule it out.
We don’t know that HGT is “extremely rare” in vertebrates. We know that it was unexpected so no one was looking for it. We also know that it is extremely inconvenient for a discipline that invested so heavily in natural selection acting on random mutations (Darwinism).
One senses that the reconstruction will be subject to considerable revision. It’s not entirely clear what “ancestry” means in a world of rampant horizontal gene transfer.
