	abstract = {<p>Throughout the last two decades much has been written on the possible cause of the well documented North American late glacial large mammal extinctions. An important explanation of this mass extinction phenomenon has been to single out human hunters as a primary cause. A new look at the sequence and nature of the factual evidence reveals another possibility. Also well documented are the large mammalian and human population expansions and dispersions which occurred during and immediately following the extinction process. As ecological niches were vacated and ecosystems changed, presenting new opportunities, the megafaunal extinctions were superseded by an actual population increase and dispersion of several remaining megafaunal genera, especially bison, major human resources. I suggest that the continuing and accelerating post-extinction human population expansion was more an effect of the megafaunal extinctions than a major cause. System feedback, normal in non-equilibrium systems, including ecosystems, however, likely contributed to a coup de gr\&rsquo;ce effect.</p>},
