    Oh, they had sensory systems for sure, but not much of a brain to speak of, according to the video.

    Without looking it up, how long do you think the Ediacaran was? What fraction of that do we have signs of multicellular life from? And how well represented is the Ediacaran in the fossil record?
    I'll say 200 million years, I don't know what fraction of that we have signs of multicellular life from off the top of my head, and as I recall, there are several main sites for Ediacaran fossils, the Burgess Shale being one of them.

    The goalposts are the same, the time left for brains and cardiovascular systems to evolve, and substantially less time for this makes evolution more problematic.

    Not so, we have hundreds of millions of years. You not only have an agenda, but a poor sense of geologic time.

    It said roughly "no brains like today's brains", if i recall correctly. That does not mean "no brains". And, as Rogue said, where do you think the input from those sensory organs was going if not to a brain?

    If you have no idea how much time there was (and your answers make clear you don't), how can you possibly say there wasn't much time for evolution to act?

    Also, Burgess Shale was Cambrian.

    Check your math. The Fuxianhuia is 520 million years ago, and the recent discovery of fungus 1000 to 900 million years ago.

    Actually they said that the brains were unlike what we see today which doesn't equate to having "not much of a brain to speak of." Anywho... The brain would still have to be at least sufficient for there to be sensory organs plugged into it and working.

    And btw, the Burgess Shale is from the Middle Cambrian -- some 508 million years ago (mya) whereas the Ediacaran spans from 635 mya to 540 mya.

    I'm always still in trouble again

    Well, she said "things that led to brains today".

    The brain would still have to be at least sufficient for there to be sensory organs plugged into it and working.
    At least a central nervous system, I still don't know that we can speak of brains in the Ediacaran.

    Yes, my memory was faulty.

    Given that this was pointed out to you a week ago, why did you keep saying "no brains" for the intervening week?

    And, while we're at it, why did you keep saying that time was so short that it creates a problem when you had no idea how much time was involved?

    Explain substantially less time when we have at least 400 to 500 million years + since fungus existed.

    Well, you said the video was ambiguous on this point, I claim that "things that led to brains today" would not be a brain.

    And, while we're at it, why did you keep saying that time was so short that it creates a problem when you had no idea how much time was involved?

    I'm estimating from the end of the Ediacaran to the appearance of Fuxianhuia, so about 540 mya to 520 mya.
