DAVID(on a different thread that's disappeared from view): I posted an article recently re the first fossil brain found in the Cambrian:
Cambrian Explosion: early brains (Introduction)
by David Turell , Thursday, July 17, 2014, 15:35 (59 days ago) @ David Turell-A jump from no brains in the Ediacarans to simple brains is a massive leap for evolution:-http://www.sciencedaily.com/releases/2014/07/140716131628.htm-QUOTE: An international team of paleontologists has identified the exquisitely preserved brain in the fossil of one of the world's first known predators that lived in the Lower Cambrian, about 520 million years ago. The discovery revealed a brain that is surprisingly simple and less complex than those known from fossils of some of the animal's prey.-I think you have slightly misinterpreted this article. If the animal's prey already had brains, this is not the first brain. It's the first predator brain they've found, and it opens up an absolutely fascinating field of evolutionary speculation, summarized in the conclusion:-QUOTE: The fact that the brain of the earliest known predator appears much simpler in shape than the previously unearthed brains of its contemporaries begs intriguing questions, according to Strausfeld, one of which is whether it is possible that predators drove the evolution of more complex brains.
"With the evolution of dedicated and highly efficient predators, the pressure was on other animals to be able to detect and recognize potential danger and rapidly coordinate escape movements. These requirements may have driven the evolution of more complex brain circuitry," Strausfeld said.-In an earlier post on this thread(10 September at 19.44), you wrote: “Brain neurons are programmed to respond to intellectual activity, and areas of the brain grow new neurons and connections.” This ties in perfectly with the above, and with evolution.
 
DAVID: Darwin cannot explain its appearance. What nest of "cell community" invented it, when it appears from no precursor?-It's not the first brain, but somewhere along the line there must have been a first brain. According to our last exchange on the subject, you had modified your 3.7-billion-year computer programme that covered every innovation and wonder throughout the history of life, and now suggested that your God had created a system that could do a great deal of its own planning, and the system was probably a layer in the genome. I have suggested a mechanism that can do a great deal of its own planning, and the mechanism is in the cell/cell community (of which, of course the genome is a part). Perhaps you can explain why you believe in a “system” but not in a mechanism that can do its own planning.
