dhw: It is therefore as clear as daylight that a larger brain is NOT required for those ideas, but is only required for their implementation. Hence my proposal of ideas first, implementation and larger brain second, as in the illiterate women’s “idea” of reading first, implementation and rewiring second.

The newly reading women used an already exiting larger brain to become literate. Size first use second.


DAVID: I presume end of discussion.

dhw: Except that you had dismissed my muscle analogy on the grounds that muscles already exist, and I pointed out that in your own examples legs, fins and brains already existed too. Just as muscles respond to exercise, I propose that legs, fins and brains respond to new uses under new conditions. Do you now accept the logic of that argument, even if you still adhere to your own theory?

No. I'm discussing the size of brains, not the form change of limbs. Muscles respond immediately enlarging with training. Brain size jumps are gaps in the fossil record, just as leg to flipper changes are gaps in the fossil record. The gaps created by speciation do not explain how larger brains are used. Artifacts are evidence of that. Apples and oranges.
