Thinking about this and the thread talking about whether physical precocity goes with giftedness: surely, "giftedness" will turn out, once we understand more, to have a multitude of different causes. I expect some will turn out to go with big heads, some with early walking, some with both, some with neither... Though we should also bear in mind the human tendency to spot patterns where none exist...
