WGS84 and NAD83 are not, themselves projections, but coordinate systems differing by the datum (or 'representations of the spheroidal earth, defined mathematically') that they use. Imagine two points which have almost no horizontally spacing, but one very high up in the air and one close to the ground.Originally, the difference between WGS84 as originally rolled out in 1987 and NAD83 as first introduced in 1986 coordinates was so small that transformation was unnecessary.
