Return to David's theory of evolution PART ONE (Evolution)

dhw: The discussion now moves to your theory that your God designs all new species in advance of the conditions that they are required to cope with or exploit. And once again, you turn the discussion to the human brain. There is no point in my repeating my whole theory, as summarized yesterday.

dhw: You have never found any logical flaw in this theory, which is supported by the fact that we KNOW the brain changes IN RESPONSE to new dequirements, and no one has ever recorded a brain changing IN ADVANCE of the requirement that the brain has to meet.

DAVID: Same old dodge. Your bold is totally illogical in face of sapiens' brain history. So big and so complex with little to do.

dhw: You seem to think that sapiens’ brain is the only complex one! It’s all a matter of degree, and it is manifestly absurd to say that there was “little to do”! The history of all the homos is full of new inventions and increasingly complex modes of living. Sapiens was not the first hunter-gatherer, maker of tools and weapons and clothes, user of fire etc. Do you think surviving indigenous people in the rainforest have “little to do” and have no brain complexity? Our brain would have reached its current size through some new requirement, and subsequent new requirements have resulted in further complexification – with such efficiency that it has shrunk. Do you really believe that the illiterate women's brains complexified BEFORE they learned to read?

You are seemingly blind to the concept of activities of daily living. How complex was the early sapiens life compared to ours? How vast was the knowledge to be used? The change is obviously enormous and requires full use of our brains, which came prepared for this degree of use.

DAVID: A cerebral cortex arrangement highly complex with five layers of neurons, not like the chimp's simple arrangement. We came from apes and God designed the many differences. The proof you want comes from logical analysis of known facts.

dhw: Yes, it’s complex compared to the chimp. Yes, we came from apes. How does that prove that our brains change IN ANTICIPATION of new requirements and not in RESPONSE to them???

How can you say, in the face of the evidence, it came in anticipation of the future. Erectus and sapiens lived in much the same simple way.
