Human evolution; Arthropithicus walking on ground (Introduction)

dhw: It is a prime example of itty-bitty evolution, proven proven by the fossil record, though we have always agreed that Darwin was wrong to claim that “Natura non facit saltum”. I’m glad you now accept that Darwin’s itty-bitty theory is at least partly true, and of course you are still left with the problem of how to reconcile this with your own anthropocentric interpretation of evolution as summarized above.

DAVID: I view nothing about the Athropithicus developments as itty-bitty. The quote above specifically states "large scale evolutionary changes' come from past history. You see iity -bitty, I don't.

QUOTES: "The way that humans walk—striding bipedalism—is unique among all living mammals, an attribute resulting from myriad changes over time. (dhw’s bold)

"'The human body has been dramatically modified by evolutionary processes over the last several million years in ways that happened to make us better walkers and runners," notes Prang. (dhw’s bold)

dhw: If the fossil record shows that bipedalism and the human body reached their final form as a result of myriad changes and dramatic modifications, how can you honestly claim that this is not an itty-bitty process?

Have you forgotten, from the fossils we have the brain size jumped 200cc each time it enlarged, which then involves birth canal problems as well as skull enlargements. Not tiny steps at any point.
