It is this accidental drift towards ghettoisation that has had such a profound impact on places like Boston.
The collective results of these studies indicate clearly that exposure to GBHs, even at sub-lethal doses such as may occur by accidental drift, can result in significant inhibition of GS crops' physiological defence mechanisms and thereby increased disease damage of crops.
New Zealander Andrew Sharp proposed the accidental voyaging hypothesis in 1957 which argued that Oceania was too vast to have been settled by intentional voyaging, so migrations must have happened by accidental drift voyages.
That part of the fauna derived from Asia, which includes the only extant native placental mammals (rats, mice, bats, and the dingo the latter probably introduced by Aboriginals), entered Australia by island-hopping or accidental drifting.

It holds that accidental mutation, random genetic drift, and natural selection together account for evolution.
The answer that we are currently using is obvious: the line is defined post hoc so that it always includes every empirically discovered case of evolution as one that could in principle be explained by traditional accidental mutation, random genetic drift and some unquantified amount of selection.
The greatest difficulty lies in accidental injury to crop plants resulting from drift and from residues in the soil, particularly if residues enter water courses.
And everything you do, just driving from A to B or totally without a destination in mind, stacks up experience points: a little drift, a near miss, the accidental destruction of a poor old guy's picket fence.
Variations of accidental eccentricities, story shear forces and story-drift ductility demands were studied.
