Secondary use at the start will get a unfastened journey, and it doesn’t inevitably retire the unique use within the demeanour of Darwin’s instance, the fish’s swim bladder that turns, after an intermediate interval of twin use, right into a lung. (That’s the place Darwin additionally cautions approximately going overboard on variations through common choice, looking at that conversions of functionality is usually relatively vital. ) The constitution can stay multifunctional. The identify usually alterations to mirror the obvious high-order use—and because the mind is superb approximately a number of use, perhaps our high-order makes use of should be noticeable during this curb-cut context. All of this, after all, is intended as parable: i would like you to determine the evolutionary improvement of advanced notion as a parallel to the new enlargement of curb-cut makes use of. yet simply because a few secondary use is feasible doesn’t suggest it immediately occurs.
